Periodic Maintenance
152379 Rev C
5–7
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.
