Maintenance Intervals

This manual is for use by qualified personnel only
Customers should follow the maintenance intervals at a minimum, however the
environmental degree of pollution at the installation may mean that maintenance
needs to be performed more frequently.
Schneider Electric recommends that the following preventative maintenance
procedures be carried out on the Xantrex inverter.
Monthly Intervals or As Required
Visually inspect the intake air ducts and external cooling fans for accumulation of
dirt and debris. Accumulation of dirt and debris within the cooling fans will
decrease their ability to move air and thus transfer heat away from the IGBT
bridge heatsink and inductor, which may cause the Xantrex inverter to enter a
Fault state based upon an over-temperature alarm. Remove any dirt or debris
obstructing the air intake or exhaust.
Electrical switchgear will need to be maintained as per the manufacturer's
recommendation.
Six Month Intervals
Perform the following preventative maintenance tasks on a six-month basis or
as required.
Enclosure Seals Inspect the enclosure door seal. If damaged, replace with equivalent closed cell
foam gasket. Call your Schneider Electric distributor for factory replacements or
specifications.
Electrical
Connections
Inspect the condition of all wiring within and interfacing to the Xantrex inverter.
Inspect all compression-type cable terminations and box-type connections within
the AC and DC interface, and the main inverter 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 Xantrex inverter
are found to be or are suspected to be unacceptable, contact your Schneider
Electric distributor for factory replacements or recommendations. Replacement
of any damaged wires is 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 increases 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-5 on page A–5. See termination torque
specifications for DC connections in Table A-6 on page A–5.
Lightning
Protection Devices
Visually inspect the indicators on the lightning protection devices (-F30, -F31,
-F32, -F33, -F34). If the visual indicators on one of -F31, -F32, or -F33 are red then
the -F35 fuses must be inspected.
Transformer and
Inductor Enclosure
Remove the access panel on the transformer and inductors and inspect for any
accumulated dirt and debris within the enclosure. Vacuum enclosure whenever
dust or dirt is present.
