Preventative Maintenance
5–6 152379 Rev C
Periodic Maintenance
Xantrex Technology recommends that the following preventative maintenance
procedures be carried out on the PV100S.
Monthly Intervals or As Required
Perform the following preventative maintenance tasks on a monthly basis or as
required.
Aluminum Extrusion Heatsink
❐
Inspect the aluminum extrusion heatsink and external cooling fan for
accumulation of dirt and debris. Accumulation of dirt and debris on the
aluminum extrusion heatsink and external cooling fan will decrease their
ability to transfer heat, which may cause the PV100S
to enter a fault state
based upon an over-temperature alarm. Remove and clean if debris is present.
Fan Operation
❐
Verify proper operation of the external cooling fan, located above the matrix
aluminum extrusion heatsink. This fan operates when the K1 contactor is
closed. If present, remove any debris from the fan.
Internal Circulation Fan
❐
Verify the internal circulation fan (B2) is operating whenever there is utility
power applied to the PV100S.
Inductor Enclosure Cooling Fan
❐
Verify the inductor enclosure cooling fan operates whenever the PV100S is
processing power. The airflow direction should be from the outside, forcing
air into the enclosure. If present, remove any debris from the fan.
