If this led is OFF it signifies a problem either with the incoming mains supply or the rectifier section. See accompanying alarm messages.

Check the following:

a)Input isolator is closed.

b)Input supply voltage is within 20% of nominal

c)Input fuses are O.K.

d)Power supply fuses are OK (Note: LS1 and LS2 on the AC Power Supply Board will be OFF if either of these fuses are ruptured).

e)Mains sensing fuses on the High Voltage Interface board F4, F5, F6 are OK.

f)Check that slide switch I2 on the UPS Logic Board is closed.

If the above checks prove satisfactory then seek qualified assistance.

If this led is OFF it signifies that either the battery circuit breaker is open or that the dc busbar voltage is below 320V dc. (For 80kVA to 125kVA models, this voltage is 330V dc ).

The battery circuit breaker will open automatically if the dc voltage falls below this level.

Check the following:

a)Battery circuit breaker is closed.

b)DC busbar voltage – if not above 320V then carry out checks as per LS1 (mains failure) above. If the dc busbar voltage is greater than 320V ( and 330V dc for 80-125kVA models); If you are unable to close the battery circuit breaker, then seek qualified assistance.

c)If the battery circuit breaker trips as soon as mains power is disconnected then check the dc power supply fuses.

If this led is OFF it signifies either that the bypass supply is not within acceptable tolerances or that the bypass supply isolator is open.

Check that the bypass supply isolator is closed, the supply is available and within specifications.
