PERATING NSTRUCTIONS
In the event of loss of mains, a battery fault or a GEN PSU fault, the corresponding Fault signal contacts will
open.
If the output of the PSU fails, the cause of the failure should be investigated e.g. short circuit load,
connection of a deeply discharged battery. The fault should be rectified before restoring power to the PSU. If
any of the fuses require replacing, ensure the correct fuse rating and type is used.
