Preventative Maintenance; Isolation Procedure - Xantrex PV-15208 Operation And Maintenance Manual

SECTION 6

PREVENTATIVE MAINTENANCE

Xantrex/Trace Technologies recommends that the following preventative maintenance be carried out
on the PV-15208:
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-15208 to shutdown on over-tempera-
ture alarms. Inspect the aluminum extrusion heatsink and fan shroud for accumulation of dirt.
Clean if debris is present.
Fan Operation
Verify proper operation of the heatsink cooling fan, located within the shroud below the enclo-
sure. The fan operates when the K1 contactor is closed. Remove any debris from the fan and
finger guard.
Six month intervals:
Enclosure Seals
Inspect the enclosure door seal. If damaged, replace with equivalent closed cell foam gasket.
Call your Xantrex/Trace Technologies distributor for factory replacements or specifications.
Electrical Connections
Inspect the condition of all cables interfacing to the PV-15208. Inspect all wire crimps and
connections for damage caused from high temperature. Check for corrosion. Replace any dam-
aged wires. Verify all mechanical connections are sufficiently tightened.
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-15208 for maintenance:
The terminals of the PV input may be energized if the arrays are energized. In
addition, allow 5 minutes for all capacitors within the enclosure to discharge af-
ter shutting down the PV-15208.
1. Turn the on/off switch to the off position.
2. Open the PV array disconnect switch (if present).
3. Open the AC disconnect (if present).
4. Open the isolation transformer circuit breaker.
5. Install lockout devices on the isolation transformer circuit breaker and PV disconnect switch.
