3.
Once the inverter has started successfully, set the SBCB
bypass switch to ‘On’ when indicated by the screen to do
so. The control logic will check the accuracy of the bypass
phase sequence and the RMS voltage value.

4.
Set the BCB switch of the batteries to ‘On’ when indicated
by the screen to do so.

Battery startup.
BCB switch operation.
The BCB switch, located in the external cabinet, can
only be closed if the DC voltage is within tolerance. Serious
damage to both the batteries and device can occur if the switch
is closed before indicated by the control panel.
5.
Set the UPS’s OCB output switch to ‘On’ to connect the
device to the loads bus. After this operation, the startup will
be complete and the screen will show the final diagram.

Basic troubleshooting.
PROBLEM
SOLUTION
After closing the RCB, the LCD remains switched off
1) Check the phase rotation of the supply voltage.
2) Verify that the input voltage and frequency are within tolerance.
3) Check rectifier protection fuses F1-F2-F3 (located inside the UPS).
After step 1, the UPS stops the startup sequence and displays one or more alarm
messages
1) Check the alarms indicated on the screen and eliminate the causes.
2) Close the RCB and try to restart the UPS.
After step 8, alarm A15 (bypass failure) appears
1) Verify that the SBCB switch is set to ‘On.’
2) Check the protection fuses of the static bypass switch (located inside the UPS).
3) Check the phase rotation of the bypass voltage.
4) Verify that the voltage and frequency are within tolerance.
After step 10, alarm A7 (BCB open) appears
1) Verify that the battery switch has been turned ‘On’; the switch and fuse holder are
located on the outside of the UPS.
2) Check the battery fuses.
3) Check the interconnection between the auxiliary contacts of the batteries (in the
external cabinet) and terminals X10-9/10.
