WARNING: Electrocution Hazard
This chapter describes specific steps to ensure the installation of the GT100 Grid-Tied
Photovoltaic Inverter is correct and complete. Failure to adhere to these warnings could
result in severe shock or possible death. Exercise extreme caution at all times to prevent
accidents. These installation instructions are for use by those familiar and skilled with
high voltage procedures.
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. 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.
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 utility main 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
five minutes for the DC bus capacitors, located within the cabinet, to discharge after
removing power.
The following procedures are intended to verify correct installation and proper
wiring of the GT100. Prior to performing the following verification steps on the
GT100, review all safety requirements and procedures outlined in this manual and
on any cautionary markings on the components within the system.
Inspect the following items prior to completion of the installation:
1. Visually inspect all the mechanical connections. This would include both
electrical conduit fittings, as well as Enclosure anchoring and seismic bracing
if required.
2. Visually inspect the electrical connections and verify proper tightness of all
terminations.
3. Visually inspect the Isolation Transformer Wye/Wye connections and ensure
the transformer neutral connection is left disconnected.
4. Perform corrective actions if required.
