Power Wiring Interconnections
NOTICE Improper installation could cause damage to the circuit boards and shorten their life. Installing circuit boards in live circuits will damage the board and is not covered by warranty. ALWAYS disconnect ALL sources of power prior to servicing.
• Remove all power prior to installing this equipment. Failure to do so could cause internal damage to the board when making electrical connections.
• Turn generator to OFF position.
• Turn off utility power to the standby generator and transfer switch.
NOTICE All wiring must be the proper gauge, properly supported and protected by conduit. All wiring should be done per applicable federal, state and local codes, standards and regulations. Obey wire type and torque specifications printed on the terminal blocks, neutral/ground connectors, and installation instructions. Approved for copper and aluminum conductors.
