PERIODIC MAINTENANCE
Xantrex Technology recommends that the following preventative maintenance be carried out on the
PV-100208:
Monthly intervals or as required:
Visually inspect the exterior surfaces for any damage (nicks, chips, exposed base
metal and scratches). Touch up or recoat using White NISSEN Feltip Paint Marker,
or equivalent to prevent rust or corrosion.
NOTE
Aluminum Extrusion Heatsink
Accumulation of dirt and debris on the aluminum extrusion heatsink and fan will decrease the
ability to transfer heat, which can cause the PV-100208 to shutdown on over-temperature alarms.
Inspect the aluminum extrusion heatsink and fan for accumulation of dirt and debris. Clean if
debris is present.
Fan Operation
Verify proper operation of the heatsink cooling fan, located above the matrix heatsink. The fan
operates when the K1 contactor is closed. Remove any debris from the fan.
Internal Circulation Fan:
Verify the internal circulation fan is operating whenever there is utility power applied to the
PV-100208.
Inductor Enclosure Cooling Fan:
Verify this fan operates whenever the PV-100208 is processing power.
Six month intervals:
(See Isolation Procedure located on page 6-2, and perform prior to the following)
Enclosure Seals
Inspect the enclosure access panel seal. If damaged, replace with equivalent closed cell foam
gasket. Call your Xantrex Technology distributor for factory replacements or specifications.
Electrical Connections
Inspect the condition of all wiring within the PV-100208. Inspect all wire crimps and connec-
tions for damage caused from high temperature. Check for corrosion. Replace any damaged
wires. Verify all mechanical connections are sufficiently tightened. Verify all conduction sur-
faces are clean and free of corrosion.
