WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

NOTICE

Use copper conductors only!

Unit terminals are not designed to accept other conductor types. Failure to use copper conductors could cause equipment damage.
