PREVENTATIVE MAINTENANCE

PERIODIC MAINTENANCE

Xantrex Technology recommends that the following preventative maintenance be carried out on the PV-225208:

Monthly intervals or as required:

NOTE

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.

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.
