PERIODIC MAINTENANCE
Xantrex Technology recommends that the following preventative maintenance be carried out on the
PV-225208:
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 heatsinks and fans will decrease the ability
to transfer heat, which can cause the PV-225208 to shutdown on over-temperature alarms. Inspect
the aluminum extrusion heatsinks and fans for accumulation of dirt and debris. Clean if debris is present.
Fan Operation
Verify proper operation of the heatsink cooling fans, located above the matrix heatsinks. The fans
operate when the K1 contactor is closed. Remove any debris from the fans.
Internal Circulation Fan:
Verify the internal circulation fan is operating whenever there is utility power applied to the
PV-225208.
Inductor Enclosure Cooling Fans:
Verify these fans operate whenever the PV-225208 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-225208. Inspect all wire crimps and connections for
damage caused from high temperature. Check for corrosion. Replace any damaged wires. Verify all
mechanical connections are sufficiently tightened. Verify all conduction surfaces are clean and free of
corrosion.
