Operating Instructions
In the event of loss of mains, a battery fault or a GEN fault, the
corresponding fault signal contacts will open (see Fault Diagnostic Table for
LED indicator status).
If the output of the PSU fails, the cause of the failure should be investigated
(for example, short circuit load, connection of a deeply discharged battery).
Rectify the fault before restoring power to the PSU. Replace any fuses with
the correct fuse rating and type as needed.
Maintenance
This unit is intended for use by Service Personnel only. There are NO USER
SERVICEABLE parts inside.
There is no regular maintenance required of the PSU other than periodic
testing and replacement of the standby batteries. Reference should be made
to the battery manufacturer's documentation to determine typical/expected
battery life with a view to periodic replacement of the battery.
