Safety Statements (continued)

· Circuit Breakers and Fuses: Installing fuses or circuit breakers not specified for use in this

equipment may result in injury to service personnel or equipment damage.

· Fuses/circuit breakers may not be provided with the equipment. Refer to the Galaxy Power

System documentation for the proper hardware. Use only those specified in the equipment

ordering guide.

· Size as required by the National Electric Code (NEC) and/or local codes. Safety Tested Limits

- Refer to the equipment ratings to assure current does not exceed: Maximum Load – 80% of

protector rating.

· GMT Style Fuses – Use only fuses provided with safety caps.

· Compression Connectors – 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.

· 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.

· Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations.

· Select wire insulation rated for a minimum of 90°C. Select wire size using NEC ampacity

table for AC field-wiring conductors rated for 75°C.

· Select DC filed-wiring conductors using NEC ampacity table for 90°C ampacity that are

equal to or greater than the circuit breaker/fuse rating.

· Provide an accessible AC and DC disconnect/protection device to remove input 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.

· Alarm Signals – Provide external current limiting protection. Rating 60V, 0.5A unless otherwise

noted.

· Grounding – Connect the equipment chassis directly to ground. In enclosed equipment cabinets

connect to the cabinet AC service ground bus. In huts, vaults, and central offices connect to the

system bonding network.
