1. The cable routing such as cable tunnel and so on.

2. The conditions required for the normal operation of the system, such as AC mains supply, earth cable and so on.

2.2.2 Distributing Goods

The user needs to distribute the goods if several systems with same model are purchased at the same time. Everysystem has been tested and gone through the burn-in test strictly before delivery. In order to ensure the optimizedoperation and track the product quality conveniently, the components should be installed in their corresponding cabinet,even though these components can be installed in other systems.

Ensure that all components in the same system have the same No. that is marked on the packing case.

2.2.3 Unpacking

Inspect the equipment strictly after unpacking to ensure successful installation.

Unpack and inspect the equipment only after it arrives at the installation site. The user representative and therepresentative from Emerson Network Power Co., Ltd. shall inspect the equipment together.

Open the packing case with a packing list in it first, take out the packing list, and inspect according to the packing list,including customer name, customer address, machine No., quantity, case No., contract No., and others.

Check the goods one by one according to the packing list after unpacking. The procedures are as follows.

Step 1: Check the quantity and serial number marked on the packing cases according to the actual quantity of the

packing cases.Step 2: Check the correctness of the equipment packing according to the packing list.

Step 3: Check the quantity and model of the accessories according to the packing list.

Step 4: Check the correctness of equipment configuration according to the system configuration.

Step 5: Check the goods visually. For example, check if the cabinet or enclosure is distorted or affected with damp;shake gently the rectifier and the monitoring module to see if there is any loose component or connection caused byshipment.

6 Chapter 2 Installation


2.2.5 Preparing Cables

The cables to be installed include AC power cables, DC power cable and grounding cable.

RVVZ cables such as flame retardant PVC insulation or jacket soft cable with copper conductors are recommended.

The cables should be able to withstand at least +70C temperature. The colors of AC phase cable, neutral cable andgrounding cable shall be red, Cambridge blue and green and yellow respectively. If the cables have the same color,

they should be identified with IDs or color labels.The sectional area of the AC power cable depends on the current, temperature rise, voltage drop and mechanicalstrength of the cable. The 2.5A/mm 2 current density is recommended to estimate the sectional area of the AC powercables and the cable with less than 10mm 2 sectional area is not recommended.

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. cable l. with 0.5V voltage drop and Min. sect. area50 A 50 A 2 10 mm 2 14 m40 A 40 A 10 mm 2 14 m25 A 12.5 A 6 mm 2 11 m16 A 8 A 4 mm 2 11 m

If the rated capacity of a MCB is much bigger than the actual output current, the MCB will not trip when overloadhappens. So the recommended MCB capacity is 1.5 to 2 times of the maximum load current.

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 thefollowing expression.

A= I L/(K U)

Where:

Asectional area of a cable (m 2)

Itotal current that flows in the cable (A)Lcable length (m)

U acceptable voltage drop in the cable (V)

Kelectric conduction coefficient, here K Copper =57

Recommended color labels for the positive and negative DC power cables:

Positive cable black

Negative cable blue

The sectional area of the grounding cable should be at least 16mm 2. A green and yellow cable should be used as thegrounding cable.

Prepare the cables according to the cabling specification and quantity. Do not join two separate cables together toform one cable. The blue and black cables should be used as DC power cables. If the cables are routed outside, theyshould be inserted into a corrugation sleeve.

The embedded power supply system has LLVD and BLVD functions. When the battery voltage is less than 47.5V(default), the embedded power supply system will disconnect the load connected to the LOAD2 ~ LOAD6 MCBsautomatically without interrupting the power to the load connected to the LOAD1 MCB. LOAD1 will be disconnectedautomatically when the battery voltage is less than 46.5V (default) to avoid battery overdischarge. At this time, allloads are disconnected.

So the priority loads should be connected to the MCB of LOAD1, that is the Route1 to Route 3 in Figure 2-12. The

normal loads should be connected to the Route 4 to Route 11 in Figure 2-12.

Step 3: Connect l oads

As shown in Figure 2-13, connect the negative polarity of every load to the lower terminal of the MCB with a negativecable, and connect the positive polarity of the load to the bolt on the positive busbar that has one M6 bolt and sevenM4 bolts.

When setting system parameters through the host, please note that:

1. Make sure that the power system address set at the host is identical with the address set through the DIP switch, orthe communication will fail.

2. Make sure that the rectifier number is set consistent with the actual condition. After a rectifier is added to or removedfrom 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 nospecific capacity requirement in the order, the default battery string capacity is 100Ah. If the actual battery capacity isdifferent from that, reset it through the host to make the configuration consistent with the actual situation and preventimproper battery management. Note: the battery string capacity (200Ah and 100Ah) can be set by DIP switch.

4. The DIP switch is in the PCB board of the monitoring module, as shown in Figure 3-2. Pull out the monitoringmodule (hot pluggable) before changing the DIP switch settings. Then you can change the DIP switch settings.

Description of DIP switch settings are given in Table 3-3.

3.4.2 System Function Test

After setting the system parameters, you can go on to carry out the system function test.

For the requirements of the test on system AC over/under-voltage alarm and protection are rather strict, you do notneed to do them. After all, the system has passed strict tests before delivery.

Battery auto-management test

Cut off AC mains supply and power the load with the battery for above 15 minutes ( 1 minute), then recover the ACmains, all rectifiers will be in current-limiting BC status.

During the current-limiting BC status, it is normal that the rectifier output voltage is sometimes below 53.5V.

For the test of battery auto-management has strict requirements for the system, it is not necessary to carry out this testif your test conditions are limited.

Rectifier on /off test

Set the control mode to background control through the host software and try turning on/off each module. Thecorresponding module should act correctly.

Note to change the control mode to automatic control after the test is finished.

Under-voltage alarm and L LVD/BLVD test

Cut off the AC power and power the load with batteries. Set the DC under-voltage alarm point, LLVD and BLVD voltageto higher values to shorten the test duration. Then observe the battery under-voltage alarm, LLVD and BLVD situation.The monitoring module should send out the corresponding alarms one by one. The red indicator on the front panel ofmonitoring module should be on, and the dry contact controlling the external audible/visual alarm equipment shouldoutput alarm signal.

Recover the AC power, restore the settings of under voltage alarm point, LLVD and BLVD voltage, and the abovealarms should disappear.

Rectifier on po sition test

Set the power system address and rectifier number correctly, insert and pull out the rectifiers one by one, and the hostshould display the communication state of corresponding rectifiers correctly.

Battery MCB off alarm test

Connect the battery to the system, and switch off its MCB. There should be a corresponding battery MCB off alarmraised at the host. The alarm will disappear when the MCB is turned on.

Load MCB off alarm test

Connect a load to the system and switch off its MCB. There should be a corresponding load MCB off alarm raised atthe host. The alarm will disappear when the MCB is turned on.

Note

1. If the terminal of corresponding load and battery route is not connected with load or battery during the test, but is suspended,the MCB Off Alarm for corresponding load or battery may not be reported accurately.2. Make sure that system configurations are restored to normal status after the test.

Viewing o peration in formation

After the system power on, you can get simple operation information through the indicators on the monitoring modulefront panel. For detailed information, you must query through the host.

Canceling b attery pr otection

If you think it more important powering the loads than protecting the battery, thus do not want the battery protection inthe case of mains failure, you can set the LLVD and BLVD status to Disabled through the host.

Note

When the battery is discharged to the BLVD voltage, the battery backup time is very short. It is impossible to obtain long timeoperation of loads by sacrificing the battery.

4.1.3 Routine Maintenance

Fan maintenance

Dust will accumulate on the baffle plate if the rectifier works in a dusty and windy environment. To ensure long-termreliable and smooth operation of the rectifier, it is necessary to clean the fan regularly (once 6 months).

In addition, the fan performance will deteriorate after long-term operation. You need to replace the fan regularly (onceevery 3-5 years).

Fan replacing method:

1. Remove the fan baffle plate

2. Remove the screws on the top right corner of the fan

3. Pull out the power cable

4. Replace the fan with a new one

5. Connect the power cable, and fix the fan with the screw on the top right corner

6. Mount the baffle plate back

26/39



4.1.4 Common Faults Handling

Fault Symptom1:

The rectifier quits operation automatically and a corresponding alarm is raised at the host.

Solution: replace the faulty rectifier.

Fault Symptom2:

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 onagain. If the over-voltage still exists, the rectifier may have been damaged and need replacing. 2) Uponmultiple-rectifier shutdown: Pull output all rectifiers and insert them one by one to find out the real faulty one. Replacethe faulty rectifier after confirmation.
