C) Connect the phase A, phase B and phase C input cables to terminals (mA, mB and mC), and connect the bypass
input cables to the bypass input copper shorting bar. Connect the input N line to the neutral terminal 'N' in the
cabinet, then connect the I/O earth cables to the PE terminal in the cabinet.
d) Connect the output cable to the output copper shorting bar, and the output N line to the output N copper
shorting bar.
e) Connect the battery positive, battery N and battery negative respectively to the Bat+, N, Bat- terminals.
This concludes the power distribution changes and cable connections.
Start-up procedures
Use the following procedures to switch the UPS on when it is in the fully switched off state.
1. Ensure that the internal maintenance bypass switch Q3 is off, and that the input cables and copper bars are
connected securely. Ensure that the input cables and copper bars are connected securely according to the 3-in 1-
out power distribution mode configuration.
Warning
To avoid generating spurious fault messages, whenever it is necessary to switch the maintenance bypass switch to the on or off
position, the operation must be completed within three seconds.
2. Before switching the system on, use a multimeter to measure the voltage on the rectifier terminals (mA-mB-mC),
and make sure that there are no circuits; if so, check that the connections are correct.
3. Unplug the REPO terminal at rear of the cabinet, and then close the rectifier input switch Q1, at this point the
system is switched on.
4. Press
, and access -> Settings (default password is ‘111111’) -> Output -> Output phase No., then set the
system to ‘1 phase’. After the system is switched off, switch it on again, access this menu once more and confirm
that this setting has been applied.

5. Set the rectifier input switch Q1 to the off position to shut the UPS down completely.
6. Plug-in the REPO terminal, close the UPS bypass input switch Q2 and the rectifier input switch Q1 in that order.
At this point, the system is switched on.
7. After the rectifier starts, close the output switch Q5 and all the external output isolation switches (if any).
8. Press the power button for two seconds to start the inverter.
