8. Maintenance
All operations inside the unit must be performed only by a service engineer from the
manufacturer or from an agent, authorised by the manufacturer.
The troubleshooting procedure gives simple remedial if a malfunction occurs in the UPS. The
operator should start the trouble shooting if there is an active alarm indicated on the LCD
screen. Service should be contacted if the active alarm is abnormal and displayed as a service
code.
Call service if you are not able to solve the problem.
Table 41. Typical alarms displayed in the LCD screen of the UPS unit.
Scrapping
Before scrapping UPS or its battery cabinet, the battery bank must be removed. Local
requirements must be followed in battery recycling or discard. The removal of batteries is
allowed only by authorised service personnel due to high energy and voltage.
Regular service/intervals
The UPS requires very little maintenance if installed in an appropriate environment.
Table 42. Routine maintenance intervals recommended by the manufacturer.
Batteries
The condition of the batteries is crucial for operation. The UPS will indicate by audible and
visual alarms if the capacity of the battery bank has decreased. The UPS units are provided with
the automatic battery test and ABM management function to continuously monitor the
condition of the battery bank.
