• Chassis ground conductor: Use two #10 AWG wires if using both chassis ground

connectors or one #6 AWG wire if using one chassis ground connector from connector(s)
to equipment rack.

Torque the nuts to 20 pound-force inches (2.2 Newton meters) maximum. Route the free end of
the chassis grounding wire to an approved office ground source. Terminate the wire at the
ground source.

Normally open (NO) and normally closed (NC) alarm contacts are provided for connecting the
circuit breaker panel to an external alarm system. Alarm connections are provided through two
single row terminal strips, each with three screws, located on the rear side of the panel. The
terminal strips can accept #16 to #30 AWG solid copper, either with crimp-on spade lugs or ring
connectors, or without lugs with insulation stripped back. Use the following procedure to
connect an external alarm system to the alarm terminals on the circuit breaker panel chassis.

1. Obtain #16 to #30 AWG wire.

2. Run four lengths of wire from the circuit breaker panel to the external alarm system.

3. Strip back the insulation approximately 0.38 inches (9.5 mm) on the ends of the wires by

the circuit breaker.

4. If using spade lug or ring connectors, crimp the connectors onto the wires and then install

the connectors on the alarm contacts (

). 

Caution:  All Vdc input wiring shall be routed away from any sharp edges and properly
secured in place to prevent chaffing and to provide strain relief. This may be achieved by
tie-wrapping the wires to the rack frame, or by equivalent means.
