1. Installation

Before the installation, please remove the internal panel, right panel, control panel, top panel of parallel UPS units. Please install the kit components for parallel UPS units as the following steps.

Install parallel control board:

If the model is EP10-40KVA UPS, please accord [1] to install parallel board; If the model is EP60-80KVA UPS, please accord [2] to install parallel board;

[1] Pull out 26P cable from J3 on system control board. Use nylon PCB support, Screw 1, Nut 1 to fix parallel board at the 4 holes before system control board, J1 and J2 of parallel board is on the left. The fixed-hole on upper right corner is grounding terminal of parallel board, use Screw 1 to connect it, use two units of Nut 1 to support between the rack and PCB board, then use one unit of Nut 1 to fix PCB board.

Parallel cable 2 is used to connect J3 of system control board to J1 of parallel board. The pulled out 26P cable from J3 of system control board is connected to J2 of parallel board.

Cable 1 Cable 2 System board Parallel board Cable 3

26P cable pulled out from J3 of system control board is connected to J2 of parallel board.

[2] Pull out 26P cable from J7 on inverter control board. Use Screw 3 to fix parallel board at the 4 fixed legs before inverter control board, J1 and J2 of parallel board is on the left.

Parallel cable 2 is used to connect J7 of inverter control board to J2 of parallel board. The pulled out 26P cable from J7 of inverter control board is connected to J1 of parallel board.

2. Install other parallel cable:

Parallel cable 1 male terminal is connected to parallel control board J4. Use Screw 2 and Nut 2 to mount supporting bracket on the bottom which is under RS232 communication port.

1) 2*4P terminal of parallel cable 3 is connected to J5 of parallel board.

2) Remove the 12 pole terminal J7 of the interface board, connect it to 5557HP/2*6P needle Cable 2 is connected J3 of system

control board to J1 of parallel board.

Connect 9 pole male side of cable 1 to J4 of parallel board.

block of parallel cable 3 .

3) 2*6P terminal of parallel cable 3 is connected to needle block J7 on interface board.

4) Bridge the cables that originate from the auxiliary of the SWMB switch using the nylon terminal. Substitute the originate cables bridged above with the two cables of parallel cable 3.

Connect the two separate terminal of cable 3 to SWMB auxiliary switch. Connect 2*4P terminal of

cable 3 to J5 of parallel board.

J7 of interface board Removed J7 terminal and 2*6P

needle block of cable 3 _{J7 of interface board} Removed J7 terminal and 2*6P

needle block of cable 3

Connect 2*4P terminal of cable 3 to J5 of parallel board.

J7 of interface board Removed J7 terminal and 2*6P

5) Substitute the connecting cable between J1 of auxiliary power supply board and J3 of SCR bypass board with parallel cable 4.

2*3P terminal (five wires) of parallel cable 4 is connected to J3 of SCR bypass board.

2*3P terminal (four wires) of parallel cable 4 is connected to J1 of auxiliary power supply board.

Remove the top cover of inverter output contactor TLI, install the auxiliary contact to TLI contactor.

Connect the two terminals that originate from SWMB auxiliary switch using the nylon terminal (10A/1P transparent)

Substitute the original cable connecting J1 of power supply board with J3 of SCR bypass board with cable 4.

2*3P terminal (five wires) of Cable 4 <——> J3 of SCR bypass board

2*3P terminal (four wires) of Cable 4 <——> J1 of power supply board

Remove the cover of TLI, install auxiliary contact to TLI contactor.

J1-1 (cable 4) is connected to the self-owned auxiliary contact 54, 62

6) Install the connection between UPS and other parts: Install short block 1 on JP3 of system control board.

Insert a male plug terminal (or female plug terminal) into the parallel terminal of first UPS unit; Use parallel connecting cable to connect the first UPS unit terminal to the second UPS unit terminal;

Use parallel connecting cable to connect the second UPS unit terminal to the third UPS unit terminal;

Insert a female plug terminal (or male plug terminal) into the parallel terminal of last UPS unit. 7) Parallel all the input and output of parallel UPS units by cables.

J3-1 (cable 4) is connected to the self-owned auxiliary contact 53 (NO) J3-3 (cable 4) is connected to the self-owned auxiliary contact 61 (NC)

3. Check the connection:

· Input / output cable is connected correctly and firmly

· Parallel connecting cable is firm, enter the UPS from the back or side · Terminal connection is firm

· Internal signal cable is connected correctly and firmly

After checking the electrical connections and internal connections, install the right panel, control panel, top cover of all the parallel UPS, internal panel is not installed temporarily.

Start up

Before starting up, please confirm that the parallel UPS units share the battery pack or use a separate battery pack for each UPS. If share the battery pack, please install a short block at JP1 on rectifier control board of all the parallel UPS units.

1. Close SWBY of first UPS unit, you can see the UPS model "RT10, P" displayed on control panel (if the UPS model is EP10K). It means the UPS unit is EP10K parallel, and this UPS is defaulted as the Master UPS of all parallel UPS units.

2. If the parallel UPS units share battery pack, get into the control panel menu: 3 -> 5, input the code: 467123. At this time you will see the UPS model "RT10, B" displays on control panel (if the UPS is EP10K). It means the parallel EP10K UPS units share the battery pack, and this UPS is defaulted as the Master UPS of all parallel UPS units.

3. Close SWIN and SWOUT of the first UPS unit, wait the UPS into normal operating mode (NOMAL OPERATION).

4. Close SWBY of the second UPS unit, you will see the UPS model "RT10, p" dispalys on control panel (if the UPS model is EP10K), it means the UPS unit is EP10K parallel, and this UPS is defaulted as the Slave UPS of all parallel UPS units.

If the parallel UPS units share battery pack, you will see the UPS model “RT10, b” displays on control panel (if the UPS is EP10K). It means the parallel EP10KUPS units share the battery pack, and this UPS is defaulted as the Slave UPS of all parallel UPS units.

Close SWIN of the second UPS unit, get into the control panel menu 2―>2 and wait till displaying I=220V. Close SWMB and then open, then all the started up UPS units switch to bypass mode. When the first UPS switches back to inverter mode, measure the voltage difference V1 of SWOUT upper and lower R, S, T phases on second UPS unit with multimeter AC posotion, if V1 <20v, then close SWOUT of the second UPS unit. Wait the second UPS into normal operating mode (NOMAL OPERATION).

Note: If the number of parallel UPS units is more than 2, other UPS starting up procedures

can repeat Step 3. When all the UPS units is on normal operating mode (NOMAL OPERATION), then the starting up of all parallel UPS units are finished.

5. Open SWBY, SWIN, SWOUT of all the parallel UPS units. Install the internal panel and start up each UPS as single UPS starting up procedure.
