10. Maintenance, Service and Repair
Regular Maintenance
Cleaning the charger air filter is the only regular maintenance
recommended.
The air filter should be inspected for dust accumulation at a 6 month
interval, more frequently if the charger is in a particularly dusty
environment.
Air Filter
The air filter may be cleaned with compressed air from the reverse
side after removal from the charger. Extremely soiled filter material
can be washed with clean soapy water and allowed to fully air dry
before refitting to the charger.
Failure to ensure the air filter is clean can lead to excessive fan
operation in order to maintain the charger module cooling during
operation. If left to operate in this way for an extended period the
risk of module fan wear increases, and charging ability is reduced
as the charger modules may de-rate output to avoid overheating.
Modules damaged by overheating due to lack of filter maintenance
will not be covered by warranty.
Blown DC Fuse
A reverse connected battery will blow the DC output fuse(s) in the
charger. A fuse blown alarm will be indicated on the front panel
display and the charger alarm logs. Fuses should be replaced only
with the same fuse as specified in the Spare Parts list.
Fuse Replacement
1. Remove the charger side panel (FS5, FS9 also remove rear
grille) and identify fuses.
FS3: Two fuses on the positive output bus bar.
FS5:
Two fuses on the rear bus bar, two on the
side bus bar.
FS9:
Same as FS5, with an additional two fuses
on the side bus bar
2. Remove each fuse and check for continuity.
3. Replace any open circuit fuses with the same fuse type.
Charger Module Fault
Charger modules found to be faulty should be removed from the
housing and returned to the Distributor for factory repair. Never
attempt to open a charger module, there are no user serviceable
parts inside and any warranty will be voided.
Charger MPC Fault
If the MPC is found to be faulty or damaged, it should be removed
from the housing and returned via the Distributor for factory repair.
A replacement controller can be factory configured with the
installation site information (battery type, capacity and voltage),
taken to site and fitted.
