As NEWMAR Power Systems are state of the art electronic systems, very little routine
maintenance is required
System
During normal operation the cable entries to the MCB's may loosen over time due to movement
in the cable strands.
To avoid damage to the MCB's and cable entries due to heat build-up and arching, it is
recommended that the retaining torque is periodically checked at least annually.
MCB's should be maintained at a torque of 2Nm
All other connections should also be checked at this time.
Monitor
The monitor can give a good indication of the condition of the system. Alarm logs can show
issues with the system and rectifiers and should be regularly checked.
As a minimum check ensure the float voltage and load current is as expected.
If the batteries are fully charged, check the battery current is zero or near to zero amps.
Rectifiers
During normal operation some dust will build-up on the front of the rectifiers. This should be kept
to a minimum by regularly wiping the rectifiers to avoid accumulation within the rectifiers and
blocking the airflow to the units. The positioning of the system and surroundings will determine
the regularity of this requirement.
In extremely dusty positions it is recommended that the units are removed and cleaned with
compressed air to prevent airflow blockages.
Batteries
Battery maintenance will depend on the individual manufacturer's specification, please contact
the battery supplier for recommendations.
