Error
Cause
Solution
MOD TH
Module thermal fault
(check the air flow,
ambient, refer to
Module Status Description
to check the internal
temperature sensor)
Check that the fan(s)
is (are) working correctly
and/or that the ambient
temperature is not too high
or whether there is poor
natural ventilation to the
charger.
If all modules
are in thermal fault,
a TH fault will follow.
MOD FUS
Module output fuse
damaged

7.3. Maintenance and service
7.3.1. WARNING: THERE ARE DANGEROUS VOLTAGES WITHIN THE
BATTERY CHARGER CABINET. ONLY A QUALIFIED PERSON SHOULD
ATTEMPT TO ADJUST OR SERVICE THIS BATTERY CHARGER.
7.3.2.
The charger requires minimal maintenance. Connections and
terminals should be kept clean and tight. The unit (especially the
heatsink) should be periodically cleaned with a low pressure air to
prevent any excessive dirt build up on components. Care should be
taken not to bump or move any adjustments during cleaning. Make
sure that both the AC lines and the battery are disconnected before
cleaning. The frequency of this type of maintenance depends on the
environment in which this unit is installed.
