Wiring - General - Xantrex GT100 Series Planning And Installation Manual

Wiring - General

153379
All wiring methods and materials shall be in accordance with the National
Electrical Code ANSI/NFPA 70, as well as all state and local code requirements..
When sizing conductors and conduits interfacing to the GT100, both shall be in
accordance with the National Electrical Code ANSI/NFPA 70, as well as all state
and local code requirements..
WARNING: Shock Hazard
The GT100 Enclosure contains exposed high-voltage conductors. The Enclosure doors
should remain closed with the latches tightened, except during installation, maintenance
or testing. These servicing instructions are for use by qualified personnel who meet all
local and state code requirements for licensing and training for the installation of
Electrical Power Systems with AC and DC voltage to 600 volts. To reduce the risk of
electric shock, do not perform any servicing other than that specified in the installation
instructions unless you are qualified to do so. Do not open the cabinet doors if extreme
moisture is present.
WARNING: Lethal Voltage
In order to remove all sources of voltage from the GT100, the incoming power must be de-
energized at the source. This may be done at the main utility circuit breaker and by
opening the AC Disconnect and the DC Disconnect Switches on the GT100. Review the
system configuration to determine all of the possible sources of energy. In addition, allow
5 minutes for the DC bus capacitors, located within the cabinet, to discharge after
removing power.
CAUTION: AC Phase Convention
When connecting external AC wires to the GT100, positive phasing sequence should be
maintained throughout the installation process. Refer to the system schematics in the unit
enclosure for proper phasing convention. The GT100 includes the ability to auto-sense
and correct for a mis-phased connection at the AC Interface terminals. In the event the
power conductors from the utility are not phased correctly at the AC Interface terminals,
the GT100 will sense the discrepancy and automatically correct for a clockwise (A-B-C)
phase rotation.
Important:
Take care to keep the wire bundles away from any sharp edges which may
damage wire insulation over time. Consult the NEC ANSI/NFPA 70 Code Book to ensure
code compliance.
The model GT100 has a three-phase, four-wire output.
Conductor size should have been pre-determined when the conduit was installed.
Prepare the appropriate length conductors for each connection.
