CAUTIONS and WARNINGS
Before installing or using the AC Modules, read all instructions, cautions, and warnings in this
Manual and on the equipment, the PV array, and in this Installation Guide.
WARNING!
Hazardous voltages are present inside AC Modules and within
circuits that connect to the AC Modules. Contact with high voltage may cause
death or serious injury. To prevent electrical shock, always disconnect all
power to unit(s) prior to servicing, and
NEVER
operate this equipment with
the covers removed.
CAUTION!
Risk of electrical shock. Do not remove inverter cover. No
installer, user or operator serviceable parts exist inside. Refer all service to a
factory service technician or qualified service personnel.
NOTE!
AC Modules are bonded to protective earth (safety ground) through
the utility ground. No other ground connection is needed. The utility ground
connection must be established prior to operating the units. The ground wire
at the service entry should be #14 AWG copper or larger, or sized as
appropriate within your local jurisdiction electrical code. If uncertain, check
with your local code enforcement office for their requirements. Input and
output circuits are isolated from the enclosure, and system grounding, when
required by the National Electric Code Sections 690.41, 690.42, and 690.43,
are the responsibility of the installer. AC output neutral is not bonded to
ground within the AC Module.
NOTE!
For domestic US installations, all electrical work must be done in
compliance with local electrical codes and the NFPA 70 National Electrical
Code.
NOTE!
Contact your electric utility company before connecting AC Modules
to the commercial electrical grid. Connections to the utility grid must be made
only by qualified personnel.
NOTE!
AC Modules are provided with fixed trip limits and shall not be
aggregated above 30 kW on a single Point of Common Connection.
NOTE!
Do not connect AC Modules into any AC circuit containing
ground-fault protective devices. Ground-fault protection devices are not
designed for back-fed power and may be damaged.
