SERVICE AND MAINTENANCE
10.1.
Recommended Annual Maintenance
Check all field wiring connections for electrical and mechanical integrity. Verify no corrosion or loose
hardware is present.
Verify that convection cooling vents are not blocked or clogged.
Ensure that air filter is clean and free from debris (see section 10.2).
10.2.
Air Filter
The charger is equipped with an air filter accessed by removing the field wiring cover (see Figure 1). An
alarm will indicate when the filter needs to be serviced. The filter can be cleaned with compressed air
and re-installed.
10.3.
Fans
The charger is equipped with two fans on the top side of the unit. The fans act in parallel, so that if a
fan failure occurs, the unit can continue to operate, though output power may be reduced depending
on continuous loads and ambient temperature. An alarm will indicate if a fan needs to be serviced or
replaced. See Figure 13 for fan servicing details. Contact SENS for replacement components and
detailed service instructions.

Supplemental Surge Protectors
If the charger was ordered with the optional supplemental surge protection (see Figure 1), these
devices may need to be replaced if operated under extensive surge conditions. Should the device need
to be replaced, indication will be provided on the LEDs, display, and alarms. Contact SENS for
replacement components and detailed service instructions.
