Battery problem:
1. When applicable, check that the external battery connections have been made correctly.
2. Measure the battery voltage to ensure it is charged and in good condition.
Recharge battery for 8 hours if necessary.
3. Simulate a utility supply outage to establish that UPS is able to provide DC back-up.
4. Seek advice from your local service agent if you find no problem with the above.
06
Emergency Power Off (EPO):
1. If the external EPO mechanism has been intentionally operated, investigate the reason and rectify any external
problems before you restore the UPS operation.
2. If the external EPO mechanism has not been intentionally operated, investigate the external EPO circuit to trace
the source of the erroneous EPO command. The external circuit applies a short circuit to the EPO connector on
the back of the UPS to effect an EPO shut down.
3. If the external EPO circuit is not faulty, seek advice from your local service agent.
Overload:
1. Disconnect any non critical loads from the UPS output until the overload ceases.
2. Check the condition of the output cables and connectors to determine that they are undamaged and the insulation
is sound. Replace the output cables if necessary.
3. Seek advice from your local service agent if you find no problem with the above.
11
UPS Over temperature:
1. Remove any objects obstructing the ventilation louvres.
2. Check to ensure that the cooling fans are working properly (see also buzzer code
14
), and contact your local
service support centre to replace the fans if necessary.
3. Seek advice from your local service agent if you find no problem with the above.
