Important Safety Instructions
SAVE THESE INSTRUCTIONS - DO NOT DISCARD
This manual contains important safety instructions for the GT Series
Three Phase Ethernet Communications Kit that must be followed during
installation and maintenance procedures.
WARNING: Shock Hazard
Read and keep this Installation Guide for future reference.
Before operating and maintaining the Ethernet Communications Kit, read all
instructions, cautionary markings, and all other appropriate sections of this
manual. Failure to adhere to these warnings could result in severe shock or
possible death. Exercise extreme caution at all times to prevent accidents.
WARNING: Shock Hazard
The Inverter Enclosures contain exposed high voltage conductors. The Inverter
enclosure doors should remain closed with the latches tightened, except during
maintenance or testing. These servicing instructions are for use by qualified
personnel who meet all local and governmental 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
(rain or heavy dew).
WARNING: Lethal Voltage
In order to remove all sources of voltage from the Inverter, 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 Switch on the
Ethernet Communications Kit. Review the system configuration to determine all
of the possible sources of energy. In addition, allow five minutes for the DC bus
capacitors to discharge after removing power. Follow the “Lockout and Tag”
procedure on page viii to de-energize the Ethernet Communications Kit.
WARNING: Shock hazard
If a ground fault has occurred, there may be potential between TB4 and GND.
The normally grounded pole may be energized and ungrounded.
