PREVENTATIVE MAINTENANCE

PERIODIC MAINTENANCE

Xantrex Technology recommends that the following preventative maintenance be carried out on the PV-30208:

Monthly intervals or as required:

Aluminum Extrusion Heatsink

Accumulation of dirt and debris on the aluminum extrusion heatsink and fan shroud will de- crease the ability to transfer heat, which can cause the PV-30208 to shutdown on over-tempera- ture alarms. Inspect the aluminum extrusion heatsink and fan shroud for accumulation of dirt and debris. Remove enclosure panels and clean if debris is present.

Fan Operation

Verify proper operation of the heatsink cooling fan, located within the lower enclosure. The fan operates when the K1 contactor is closed. Remove any debris from the fan and finger guard.

Six month intervals:

(See Isolation Procedure 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-30208. 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.

Mechanical electrical connections will loosen over time. This is caused primarily by thermal cycling during normal operation. As connections loosen, electrical impedance will increase at the connection, eventually leading to fire and component damage. It is critical to check all electrical connections every six months.

Enclosure

Access the enclosure and remove any accumulated dirt and debris. Vacuum enclosure whenever dust or dirt is present.

ISOLATION PROCEDURE

The following procedure should be followed to de-energize the PV-30208 for maintenance:
