ROUTINE INSPECTION AND MAINTENANCE
The unit should be inspected and cleaned at least annually or more frequently if it is in an excessively warm,
salty, or dusty environment.
Overall: Perform a visual inspection checking for things such as discolored wires or terminals, evidence of
arcing, loose mounting screws, physical damage to the enclosure, etc.
Power terminals: Inspect for loose connections and tighten to specifications in .
Capacitors: Check for leakage or deformation.
Fans and heatsinks: Excessive dust buildup on the heatsink and cooling fan impellers may lead to
overheating. Lightly brush and vacuum clean. Contact Customer Service for assistance in replacing the
cooling fan in the event it should fail. Use only fans approved by Phase Technologies. Unapproved fans may
fail to cool the unit properly, risking component damage.
Battery
The drive is equipped with a battery that provides power to a real-time clock. The clock allows faults to be
stamped with time and date. The battery is located on the control printed circuit board. It is a button cell lithium
battery rated at 3.0V, type CR2032. The battery should last many years under normal operating conditions. If
the battery fails, the drive will continue to operate normally; losing only the ability to timestamp faults and
provide timed operation of programmable relays.
