2.2 Safety Precaution

DANGER ● DANGER due to electrical shock and high voltage.

● Do not touch the operating component of the inverter; it might result in

burning or death.

● To prevent risk of electric shock during installation and maintenance,

please make sure that all AC and DC terminals are plugged out.

● Do not touch the surface of the inverter while the housing is wet, it might

lead to electrical shock.

● Do not stay close to the inverters while there are severe weather

conditions including storm, lighting, etc.

● Before opening the housing, the CPS inverter must be disconnected from

the Grid and PV generator; you must wait at least five minutes to let the

energy storage capacitors fully discharged after disconnecting from power

source.

WARNING ● The installation, service, recycling and disposal of the inverters must be

performed by qualified personnel only in compliance with national and local

standards and regulations.

● Any unauthorized actions including modification of product functionality

of any form may cause lethal hazard to the operator, third parties, the units

or their property. CPS is not responsible for the loss and deny these

warranty claims.

● CPS inverters must only be operated with PV generator. Do not connect

any other source of energy to the inverters.

● Be sure that the PV generator and inverter are well grounded in order to

protect properties and persons.

4.2 Mounting Instructions

● Mounting on a solid surface out door or indoor.

● Site altitude is less than 2,000m above the sea level.

● The mounting location must be clear and safely accessible at all times without the use of additional aids such as scaffolding or lifting platforms. If this is not the case, service work may be restricted.

● Mount vertically or tilted backwards by max. 15°

● The connection area must point downwards.

● Never install the inverter forward tilt, sideways tilt, horizontally or even upside down.

Install the inverter at eye level for convenience checking the LCD display and possible maintenance activities.

● Given the weight of the device, this will facilitate disassembly for service work.

● The ambient temperature should be below 45°C to ensure optimum operation. Choose locations with sufficient air exchange. Ensure additional ventilation, when necessary.

● Do not expose the inverter to direct solar irradiation as this could cause power derating due to overheating.

● In order to avoid audible vibrations in living areas, do not mount the unit on plasterboard walls or similar.

● Observe the recommended clearances to walls, other inverters or other objects, as shown in the follow diagram. That ensures sufficient heat dissipation and gives you enough space to unplug the PV Connector, communication port and operate the DC-switch.

Note: The cable loss due to the cross section and the length, to avoid too much power loss, user can select the proper cable according the actual situation. The below chart specific the relationship among the Cable Loss, cross section, cable length.

24 25


4) Use a screw driver and loose the three screws at the side of the straight plug. Then insert the stripped N, L and PE cable according to the corresponding position and fully tighten the screws.

NOTE: ● The PE conductor must be 5 mm longer than the L

and N conductor.

● L and N must not be swapped. Reverse connection

may cause the inverter can not work normally or

even damage the inverter.

5) Aim the terminals on the straight plug to the holes of the grommet, and then compress them together.

5.5 DC connection procedure

5.5.1 Conditions for DC Connection

CPS SCJ1KTL, CPS SCJ1KTL, CPS SCJ2KTL Single MPPT, one DC input connection set per MPPT.

CPS SCJ3KTL, CPS SCJ4KTL, CPS SCJ5KTL:Dual MPPT(PV1 and PV2), one DC input connection set per MPPT. The default setting of Double MPPT is independent mode.So you can install two Solar panels that are in different numbers or directions .The system is more flexible.

5.4 AC connection procedure

1) Strip the cable with the length 0.276 inches (9/32″) - (7mm) and please be careful NOT to nick conductors.

2) Screw off and separate each component of AC connector as follows.

3) Pass the cable through each component from right to the left as follows.

Tighten the screws with 3.0N·m torque.

26 27


3) Insert stripped cable into contact barrel and insure all conductor strands are captured in the contact barrel and the conductors are visible in the contact barrel observation hole.

Barrel observation hole Conductor should be visible

Ethernet :

The inverter can get an IP address from router by using DHCP (Dynamic host

configuration protocol) or user can set a fixed IP.

If user manually set an IP address, the inverter will use it all the time until reset a new one or use DHCP model to get an IP addr.

Change Password:

User can change the password by the “Change Password” menu.

Clear Errors

Be caution that this operation will clear up all the history error records.

If user wants to clear up the history error records, move the cursor and press ENT to enter the sub-items, press ENT to confirm the setting when the below menu occurs. Press ESC or ENT to exit when “Set Complete!” appears.

Clear Energy:

Be caution that this operation will clear up the generated energy data of E-Today

、E-Month、E-Year、E-total、T-Today、T-Total etc. If user wants to clear up the generated energy record, move the cursor to “clear energy” and press “ENT” to enter the sub-items, press “ENT” to confirm the setting when the below menu occurs. Press ESC or ENT to exit when “Set complete!” appears.

Factory Setting:

Note: This operation will erase all history data record, such as generated energy, error logs etc. And the password and Grid Compliance will be set back to default

settings.

Enter “Factory Setting” menu to enter the password, the system will required

users to re-confirm “Factory Setting”. Press “ENT” button to confirm. You can

see “Set complete” to finished the “ Factory setting” and press “ESC” or “ENT”to exit the “ Set complete”

7.9 Set-Param

Note: Every parameter is effective after the below menus have been confirmed.

Date :

This setting includes year, month and date”. Press “▼ ” or “▲ ” button to

choose one of the items: year/ month/date, press ENT to make the cursor “^”

point to the selected item. Then press “▼” or “▲” button to set the parameter.

Press ENT to confirm this item setting, then it automatically points to the next

item setting. Repeat the operation steps to set other item.

When the three items have been set, “Are you sure to set it?” will appear; press

ENT to confirm it. Then press ESC or ENT to exit when “Set Complete!”

appears.

Time :

This setting includes “hour, minute and second”.

Please refer to the operation steps of “Date Setting”.

Grid Compliance:

The Gird Compliance may be different in the different countries. If the chosen

country of “Grid Compliance” is incorrect, we can modify it.

Set complete!Are you sure to set it?

8. Product maintenance procedures

In order to reduce the risk, inverter should not be exposed in harsh environment such as rainy day,frosting day,science, in fog,greasy and large amounts of dust;Do not install the inverter in the sealed space;Don’t cover and block the vents, or the inverter will be damaged by the overheating.

The inverter should avoid fire and lightning strikes. Any unqualified wire may damage the inverter.

Because the inverter itself can produce arc components, so it can not be installed in the flammable, explosive environment where including batteries and inflammable materials and without protection equipment side that including: the component system of gasoline engine, fuel cylinder or other in the fuel side.

You should keep the inverter in the proper preventive maintenance and maintenance. Using wet cloth to clearn the external of the nverter and stains. At the same time you should tight the DC input terminal screws; Clean the dust of the inverter surface by using a high pressure gun .

You should close the inverter before cleaning and maintaining the machine.

9. Devanning

1、Unscrew the screws that on the four sides of the rear panel.

3、When the machine is pushed to the top of the screen, you can remove the machine from the front.

10. RECYCLING AND DISPOSAL

WARNING This device shall not be disposed of in residential waste.

To comply with European Directive 2002/96/EC on waste Electrical and

Electronic Equipment and its implementation as national law, electrical

equipment that has reached the end of its life must be collected separately and

returned to an approved recycling facility. Any device that you no longer

required must be returned to your dealer or you must find an approved

collection and recycling facility in your area.

Ignoring this EU Directive may have severe affects on the environment and

your health.

11. TROUBLESHOOTING
