Maintenance Safety
Never work alone when servicing this equipment. A team of two is required until
the equipment is properly de-energized, locked-out and tagged-out, and verified
de-energized with a meter. See “Maintenance Intervals” on page 6–2. Thoroughly
inspect the equipment prior to energizing. Verify that no tools or equipment have
inadvertently been left inside the equipment.
Maintenance Intervals
Maintenance intervals must be adhered to in order to ensure that the Xantrex
inverter continues to operate in a way that is as safe and reliable as possible. The
basis for these maintenance intervals is installation in an environment with an
average annual ambient temperature of +20 °C, with cooling air maintained
within the temperature limits stated in the Specifications.
WARNING: Risk of electric shock, explosion, and arc
flash
Before performing maintenance on the Xantrex inverter read all instructions,
cautionary markings, and all other appropriate sections of this manual. Exercise
extreme caution at all times to prevent accidents.
Failure to follow these instructions will result in death or serious injury.
WARNING: Risk of electric shock, explosion, and arc
flash
The Xantrex inverter enclosures contain exposed conductors and parts operating
at lethal voltage and at high enough energy to create an arc flash. Electrocution or
severe burns may result. The enclosure doors should remain closed with the
latches tightened, except during installation, maintenance or testing. These
instructions are for use by qualified personnel. To reduce the risk of electric shock
or arc flash, do not open any doors or remove any covers unless you are qualified
to do so, are properly equipped with appropriate personal protective equipment,
and have followed “Lock-out and Tag-out” on page viii to lock-out and tag-out all
sources of energy and verified that the inverter is de-energized. Do not open the
cabinet doors if moisture is present (rain or heavy dew).
WARNING: Risk of electric shock, explosion, and arc
flash
The Xantrex inverter is energized from the PV array, from the AC grid, and from
an auxiliary AC source (backed up with a Xantrex UPS for Xantrex GT500 E &
Xantrex GT630 E units with low-voltage ride-through capability). All 3 sources
(4 including a Xantrex UPS) must be disconnected, locked-out and tagged-out,
and all circuits tested to verify that the inverter is fully de-energized, before
servicing or maintenance, as described on page viii. Opening the AC and DC
disconnect switches on the inverter does not remove all power from the inverter.
Wait 20 minutes for the DC bus capacitors, located within the cabinet, to
discharge after removing power.
