Safety Statements, continued
• Fuses/circuit breakers may not be provided with the equipment.
Refer to the Galaxy Power System documentation for the proper
hardware. Use only the parts specified in the Galaxy Power
System (GPS) documentation. Installing fuses or circuit breakers
not specified for use in this equipment may result in injury to
service personnel or equipment damage.
• For installations in the U. S. or Canada, use Listed/Certified
compression connectors to terminate Listed/Certified field-wire
conductors where required. For all installations, apply the
appropriate connector to the correct size conductor as specified by
the connector manufacturer, using only the connector
manufacturer’s recommended tooling or tooling approved for that
connector. If the proper connector for the country of installation is
not provided, obtain appropriate connectors and follow
manufacturer’s and all local requirements for proper connections.
Follow all national and local rules and regulations when making
field connections.
• Torque electrical connections to the values specified on labels or in
the product documentation.
• Battery input cables must be dressed to avoid damage to the
conductors (caused by routing around sharp edges or routing in
areas where wires could get pinched) and undue stress on the
connectors.
• Either external fuses or external circuit breakers must be sized as
required by the National Electric Code (NEC) and/or local codes.
Refer to the equipment ratings to assure rating of equipment will
not exceed 80% of the value of the protector chosen. Refer to the
system T-drawing (wiring diagram) for recommended circuit
protection for the different options.
• The ac input distribution has been evaluated for connection of
minimum 90°C conductors sized according to the US National
Electrical Code using the 90°C ampacity tables. Torque electrical
connections to the values specified on labels or in the product
documentation.
• Provide an accessible ac disconnect/protection device to remove ac
power from the equipment in the event of an emergency. This
device must open all poles and be connected together. When
connecting to 3-wire plus neutral supply systems, the neutral must
be readily earthed at the supply, i.e., this equipment is not intended
to be connected to IT supply systems.
