Xantrex Technology PV100S-208 manual Six-month Intervals, Enclosure Seals, Electrical Connections

Periodic Maintenance

Six-month Intervals

Perform the following preventative maintenance tasks on a six-month basis or as required.

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 and interfacing to the PV100S.

❐Inspect all compression-type cable terminations and box-type connections within the AC and DC Interface Enclosures, Main Inverter Enclosure, and Transformer Enclosure for damage caused from high temperature.

❐Also check these terminations and connections for signs of corrosion. If any cabling or wiring within and interfacing to the PV100S are found to be or are suspected to be unacceptable, contact your Xantrex Technology distributor for factory replacements or recommendations. Replacement of any damaged wires will be necessary.

❐Verify all mechanical connections are sufficiently tightened. Verify all conduction surfaces are clean and free of corrosion. Mechanical electrical connections may loosen over time primarily due to thermal cycling during normal operation. As electrical connections loosen, impedance will increase at the connection, eventually leading to possible fire and component damage. It is critical to check all electrical connections every six months.

See termination torque specifications for AC connections in Table A-4 on

page A–4.See termination torque specifications for DC connections in Table A-5 on page A–4.

Inductor Enclosure

❐Remove the access panels on the inductor enclosure and inspect for any accumulated dirt and debris within the enclosure. Vacuum enclosure whenever dust or dirt is present.
