Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Caution We recommend grounding the chassis, even if the rack is already grounded.

Note If the rack is less than 25-in. (635 mm) deep, the slider rails will cover the grounding hole. Therefore, the rack must either be grounded or at least 25-in. (635 mm) deep.

Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.

Note The grounding lug must be NRTL listed and compatible with copper conductors. Only copper conductors (wires) must be used and the copper conductor must comply with National Electrical Code (NEC) for ampacity.
