SECTION 6: ROUTINE MAINTENANCE
GENERAL
1 Routine maintenance should be carried out on a six monthly and annual basis as detailed below.
SIX MONTHLY CHECK
2The following must be carried out every six months:
2.1Check that the unit output voltage is within the normal operating limits of the external power system (refer to the power system manufacturer's handbook).
Note
Voltages outside the normal operating range may be attributed to a recent interruption of the dc supply.
2.2Check that the LVD PCA LED is lit.
2.3Make a visual inspection for mechanical damage, signs of overheating and damaged cables, terminals and insulation.
2.4Check that all electrical connections and mechanical fixings are secure.
3Record any faults in the service log.
ANNUAL CHECK
4As well as the six monthly checks listed in Para 2, it is recommended that a battery discharge test is carried out on a battery connected to the unit output. For details, refer to the battery manufacturer's documentation.
