Safety Precautions

To reduce the chance of accidents, please read the safety precautions carefully before operation. The “Caution, Notice, Warning and Danger” in this manual do not represent all the safety points to be observed, and are only used as supplement to various operation safety points. Therefore, the installation and operation personnel must be strictly trained and master the correct operations and all the safety points before operation. When operating Emerson products, the safety rules in the industry, the general safety points and special safety instructions specified in this manual must be strictly observed.

Electrical Safety

I. Hazardous voltage

Danger Some components of the power system carry hazardous voltage in operation. Direct contact or indirect contact through moist objects with these components will result in fatal injury. Safety rules in the industry must be observed when installing the power system. The installation personnel must be licensed to operate high voltage and AC power. In operation, the installation personnel are not allowed to wear conductive objects such as watches, bracelets, bangles, rings. When water or moisture is found on the cabinet, turn off the power immediately. In moist environment, precautions must be taken to keep moisture out of the power system. "Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during installation.

Danger High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high voltage operations. II. Tools

Warning In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used. III. Thunderstorm

Danger

Never operate on high voltage, AC, iron tower or mast in the thunderstorm. In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be well earthed in time to avoid damage by lightning strikes.

IV. ESD

Note The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale ICs. Before touching any plug-in board, PCB or IC chip, wear ESD wrist strap to prevent body static from damaging the sensitive elements. The other end of the ESD wrist strap must be properly earthed. V. Shortcircuit

Danger

During operation, never short the positive and negative poles of the DC busbar or the non-earthing pole and the earth. The power system is constant voltage DC power equipment; short circuit will result in equipment burning and endanger human safety. Check carefully the polarity of the cable and connection terminal when performing DC live operations. As the operation space in the DC power distribution unit is very tight, please carefully select the operation space. Remove watch, bracelet, bangle, ring, or other conductive objects before operation. Use insulated tools. In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of the human body and tool is reduced to the minimum.

Battery

Danger Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery connection method. Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs, thus causing equipment damage and short circuit of PCBs. Before any operation on battery, pay attention to the following points: Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist. Use special insulated tools. Use eye protection device, and take preventive measures. Wear rubber gloves and apron to guard against electrolyte overflow. In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery upside down or slanted.

Installation Precautions

1. Only qualified technical person can perform the system installation and maintenance. 2. Avoid fire or body injuries. 3. Provide suitable AC mains supply to the system. 4. Earth the system according to the requirement. 5. Keep the environment of the system clean and dry. 6. Avoid touching the bare part of a circuit.

7. Switch off the circuit breakers in case of system failure.

Others

I. Safety requirement

Notice Always use the same model MCB to replace the old ones to comply with the safety requirement. II. Sharp object

Warning When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object. III. Cable connection

Notice Please verify the compliance of the cable and cable label with the actual installation prior to cable connection. IV. Binding the signal lines

Notice The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least 150mm.

1.3 Composition

The APM100 outdoor power supply consists of an equipment compartment and a battery compartment. The equipment compartment contains embedded power supply, heat exchanging equipment, external fan and distribution unit etc. The battery compartment has one layer, and a set of batteries that supplies backup power can be placed in the layer. In the north model system, two heaters are placed respectively in the equipment compartment and in the battery compartment. See Figure 1-2.

Figure 1-2 Composition of APM100 outdoor power supply system

Embedded power supply

The embedded power supply consists of three rectifiers, one monitoring module, one distribution subrack and one monitoring expansion board. It converts the 220V AC voltage into -48V DC voltage, and delivers the -48V DC voltage to the system distribution units and then to the load through the distribution subrack.

Heat exchanging equipment and external fan

The heat exchanging equipment dissipates the heat inside the cabinet with the external fan. It consists of an internal fan and a heat exchanger. The external fan aspirates the cold air outside and feeds it to the heat exchanger, while the internal fan expels the heat air inside the cabinet to the heat exchanger. The heat exchanger exchanges the heat between cold air and hot air in it to dissipate the heat.

Distribution unit

The distribution unit includes panel, AC/ DC SPD, connection terminals and MCBs. It is used to connect the AC input cables and load cables.

Reserved space

Reserved to place user devices.

Heaters

There are two heaters in the north model system; one is located behind the panel of the distribution unit in the equipment compartment and the other at the top of the battery compartment. The two heaters will start to work when the ambient temperature is below 5°C (due to thermostat error, the actual temperature range of startup is 0°C ~ 10°C) to ensure the normal operation of the north model system segments in low temperature environment.

Figure 1-3 Schematic diagram

The embedded power system rectifies the 220V AC power into -48V DC power and delivers it to the distribution unit. It has functions of battery management, load low voltage disconnection (LLVD), BLVD, data acquisition, alarm, and communication with the host. The distribution unit connects the AC mains to the embedded power supply. It also outputs -48Vdc to the loads through different routes.

1.5 System Function

1.5.1 Protective Function

LLVD and BLVD

When mains failure occurs, the battery will supply power. When the battery voltage drops to 47.5V (default, adjustable), the monitoring module will cut off the non- priority loads. When the battery voltage drops to the BLVD voltage (46.5V by default), the monitoring module will cut off all the loads to avoid battery overdischarge. When the mains resumes, the power system will go back to normal state.

Over- temperature protection

If the temperature of the equipment compartment exceeds the protection point (65°C by default) for 30 seconds, the monitoring module will cut off the non- priority loads until the ambient temperature drops below 45°C. If the temperature of the battery compartment remains over the protection point (53°C by default) for 30 seconds, the monitoring module will cut off the connection between system and batteries until the ambient temperature drops below 45°C. Under this condition, if AC side failure occurs, all the loads will be cut off. This function is inhibited by default, though the user can activate it through the host.

Input under-voltage protection

When the AC input voltage is over 290Vac or below 90Vac, the rectifier will perform self- protection. It can recover automatically, and the return difference is more than 5Vac.

Output over-voltage protection

When the DC output voltage is over 60.5V, the rectifier will stop exporting voltage or current. This protection cannot recover automatically.

Output current- limiting protection

The APM100 system can perform current- limiting protection. The current- limiting protection point is 61.5A ± 1.5A.

Output shortcircuit protection

The APM100 system can perform shortcircuit protection. It can be shorted for a long while and recover automatically. The shortcircuit protection current is ≤ 6A.

1.5.2 Alarm Function

The system raises alarm on the following occasions: mains failure, mains over/ under- voltage, DC output over/ under- voltage, charging overcurrent, load over- temperature protection, ambient over- temperature, module failure, module protection. The alarm levels are divided as critical alarm, observation alarm, and inhibitive alarm. Alarms that may cause load power interruption are defined as critical alarm by default, and the rest are observation alarms. Only door status sensor alarms, humidity alarms and backup equipment alarms can be set as non- alarm and be shielded. Unless otherwise stated (Battery charging overcurrent: 5 minutes; Failure of battery- compartment heater: 1 hour; Battery imbalance alarm: 30 seconds), the confirm time of the alarm is ten seconds. See Table 1-1.

(a) Installed at the lower platform of the iron tower （b） Installed inside the outdoor room

（c） Installed inside the pole- holding platform （d） Installed at the roof

Figure 2-1 Examples of site selection and installation mode

Chapter 2 Installation Preparation 7


2.2 Laying Grounding Net

To ensure the safe and reliable operation of the power supply system, the grounding devices must be installed before the cabinet installation. Requirements of the grounding equipment:

Vertical grounding equipment: Φ 50mm galvanized steel tube, 2m long;

Horizontal grounding equipment: 40 × 4mm galvanized flat steel, length as demanded;

Galvanized angle steel: 50 × 50 × 5mm, 2m long;

Grounding leading -in: 40 × 4mm galvanized flat steel, length as demanded.

2.3 Leading In Power

The power supply of the APM100 cabinet is 220Vac/ 110Vac. The AC power is usually led in on the stilts, from the secondary side of the nearby transformer through an AC MCB with capacity over 63A. The power cable of the lattermost level should be no longer than 10m and shielded by metal layer. Both ends of the metal layer should be grounded. The endurable voltage of the power cable should be larger than 300Vac and the endurable frequency should range between 40Hz to 65Hz.

2.4 Preparing Cable Tunnels

All the outside cables should be equipped with cable tube or cable tunnels for protection. Lay the cables at the cable tunnels and take moisture-proof, mouse-proof and fireproof measures.

2.5 Cable Requirements

The cables to be installed include AC power cables, DC power cable and grounding cable. The cables should be able to withstand the temperature of at least +70°C. The descriptions of different cables are as follows:

1. AC cables

Temperature rise, voltage drop and mechanical strength should be comprehensively considered when selecting the sectional areas of the AC cables. If the AC cable is shorter than 15m, it is recommended to use cables with sectional area larger than 4mm2 (larger than 12AGW cable). If the AC cable is longer than 15m, please choose the cable size according to site operation. Note: The cabinet is furnished with one piece of 10m two- core cable (2×12AWG) with jacket as accessory.

2. DC cables

The sectional area of the DC power cable is shown in Table 2-1.

Table 2-1 Sectional area of the DC power cable

Rated current Max. output current Min. sect. area Max. dual- cable length with 0.5V volt. drop and Min. sect. area 32 A 16 A 16 mm2 7 m 20 A 10 A 10 mm2 7 m 16 A 8 A 6 mm2 5.5 m 10 A 5 A 4 mm2 5.5 m

If the rated capacity of a MCB is much bigger than the actual output current, the MCB will not trip when overload happens. So the recommended MCB capacity is 1.5 to 2 times of the maximum load current (two times in the table above).

Note The maximum output current that flows in the DC power cable is calculated according to the full load of the system. If the acceptable voltage drop is not 0.5V, determine the sectional area of the DC power cable according to the following expression. A= I%L/(KΔU)

8 Chapter 2 Installation Preparation


Where: A—sectional area of a cable (m2)

I—total current that flows in the cable (A) L—cable length (m) ΔU— acceptable voltage drop in the cable (V) K—electric conduction coefficient, here K Copper=57 Please choose the cable color according to local standards. It is recommended to use black cables as positive DC cables and blue as negative DC cables.

3. Grounding cables

The sectional area of the grounding cable should be at least 16mm2. The green- yellow cables should be used as the grounding cables. Prepare the cables according to the cabling specification and quantity. Do not join two separate cables together to form one cable.

2.6 Requirements Of Laying Cables

1. Tag the AC cables and load cables should with numbers and polarities. Tag the cables at both ends. 2. The cables should be intact and have no flaw. 3. If the cables are routed outdoors, they should be put into plastic coated metal hoses or steel tubes, as shown in Figure 2-2.

Plastic tubes do not have the lightning protective function. Steel tubes should be used.

Figure 3-22 Relationship between two levels of MCBs

The embedded power supply system has LLVD and BLVD functions. When the battery voltage is less than 47.5V (default), the system will disconnect LOAD5 and LOAD6 automatically without interrupting LOAD1 ~ LOAD4. However, LOAD1 to LOAD4 will be disconnected automatically when the battery voltage is less than 46.5V (default) to avoid battery overdischarge. At this time, all loads are disconnected. The priority loads should be connected to the MCB of LOAD1 to LOAD4, that is Route1 to Route 9 in Figure 3-18. The non-priority loads should be connected to Route 10 and Route 11 in Figure 3-20. The load capacity should be no larger than the capacity of the MCB that is in the same route.

Connecting AC power cables

After confirming load distribution, you can connect AC power cables and load cables. The terminal and MCB positions are shown in Figure 3-23.

5) Fix the AC cable to the cable frame with a nylon tie, as shown in Figure 3-26.

Note 1. The grounding cable shall be connected first, then the neutral line and finally the phase lines. 2. The AC cables should be routed from the MCB in the external distribution equipment prepared by user. They should be connected to the MCB just before the system is powered on. The external distribution equipment should have some protection devices to fulfill the overcurrent, shortcircuit and lightning protection functions. 3. The AC phase line, neutral line and grounding cable should be identified with color labels. 4. The AC cables should be routed away from the DC cables. 5. It is recommended to use the 10m cable of the accessories as the AC cable. If users use their own cables as the AC cable, they should screw down the cap of the cable tunnel and use silicon sealant to seal the cable tunnels after connecting cables. If users use accessory cable as the AC cable, screw down the cap of the cable tunnel after connecting cables. 6) Place the protective cover over the cable hole after AC cable connection. 2. Cable connection for system with 110V AC input The AC transfer terminal of the systems with 110V AC input is different from that of the system with 220V AC input, as shown in Figure 3-27. 1) The procedures of step1 to step 3 are the same with those of 220V input cable connection.



2) Connect the three cables labelled ‘N’, ‘L1’ and ‘L2’ to N terminal of the AC transfer terminals, and L1 and L2 terminals of the bottom of the AC MCB, as shown in Figure 3-27. 3) Fix the AC cable to the cable frame with a nylon tie.

Make sure that the power system address set at the host is identical with the address set through the DIP switch, or the communication will fail. 2. Make sure that the rectifier number is set consistent with the actual condition. After a rectifier is added to or removed from the power system, the rectifier number parameter must be accordingly modified, or a rectifier alarm will be raised. 3. The battery string capacity setting is customized according to order requirement before delivery. If there is no specific capacity requirement in the order, the default battery string capacity is 100Ah. If the actual battery capacity is neither 100Ah nor 200Ah, reset it through the host to make the configuration consistent with the actual situation and prevent improper battery management. 4. If the battery string capacity is 100Ah or 200Ah, you can set the battery capacity by the DIP switch. The DIP switch is in the PCB board of the monitoring module, as shown in Figure 4-6. You need to pull out the monitoring module (hot pluggable) first before you can change the DIP switch settings. Refer to 5.4 Replacing Modules for the method of plugging monitoring module.

5.3 Alarm Handling

Fault 1: The rectifier quits operation automatically and a corresponding alarm is raised at the host. Solution: replace the faulty rectifier. Fault 2: Rectifier(s) is/are shut down upon over-voltage and the corresponding alarm is raised at the host. Solution: 1. Upon single rectifier shutdown: Switch off the faulty rectifier. Wait till its indicators are off, and switch it on again. If the over-voltage still exists, the rectifier may have been damaged and need replacing. 2. Upon multiple-rectifier shutdown: Pull output all rectifiers and insert them one by one to find out the faulty one. Replace the faulty rectifier after confirmation.

5.4 Replacing Modules

Upon abnormities, the rectifier may need to be pulled out and plugged in. The rectifiers and monitoring modules are all hot swappable. Do not touch the back board of the rectifier subrack. To pull out the rectifier, first you should draw out the handle at rectifier front panel to detach the latch at rectifier bottom from the distribution frame. Then you can pull the rectifier out by the handle. The handle position is shown in Figure 5-3.

Rectifier handle

Figure 5-3 Pulling out rectifier handle



To remove the monitoring module, first you need to remove the communication cable with a screwdriver and then pull out the signal cable, as shown in Figure 5-4. Otherwise you cannot pull out the monitoring module.

HandleFixing screws Figure 5-4 Pulling out monitoring module

The procedures for removing/inserting the monitoring module are the same as those for the rectifiers. After plugging in the monitoring module, you should first connect the signal cable and then connect the communication cable.

Note The rectifiers’ connecting part is a delicate device. Although the rectifiers are designed to be hot pluggable, the pull-out and plug-in operation should be gentle lest the connecting part should be damaged. Only professionals are allowed to conduct rectifier replacement.

5.5 Replacing Rectifier Fan

Dust will accumulate on the baffle plate if the rectifier works in a dusty and windy environment. To ensure long-term reliable and smooth operation of the rectifier, it is necessary to clean the fan regularly (once half a year). In addition, the fan performance will deteriorate after long-term operation. You need to replace the fan regularly. Procedures of replacing rectifier fan are described as follows. 1. Pull out the rectifier. 2. Remove the fan baffle plate. 3. Remove the screws on the down right corner of the fan, as shown in Figure 5-5. 4. Pull out the power cable of the fan, as shown in Figure 5-5.

48 Appendix 3 Common Problems


Appendix 3 Common Problems

After installation and testing, the system is ready for use. When necessary, it can be put into normal operation just by switching on the corresponding MCB. During the operation, the following issues may call your attention:

Fan speed control technology

The fan may run for a second and stop when the rectifier is powered on for the first time. If load is connected to the system, the inner temperature of the rectifier will increase after operation for a period of time, and the fan will begin running and speed up with the increase of inner temperature. That phenomenon is due to the fan speed adjusting technology, and thus absolutely normal.

Over temperature protection

A rectifier’s inner temperature may be high during operation. If you reset it by turning it off and on at that time, you may observe that the rectifier has no output but the fan is running. That is because the over temperature protection circuit within is working. The output will recover after the temperature decreases one minute later. If the fan does not run, and the rectifier has no output for more than five minutes, the rectifier may have been damaged. Please replace the faulty rectifier or contact Emerson local service center.
