Attach a Ground Cable to the C150/300 DC

Chassis

WARNING: You must complete the ground connection before proceeding

with any DC PEM connection.

The AC power cord is the primary ground connection for C-Series AC chassis.

This procedure applies to the DC powered chassis only.

You must provide your own cables to connect to a remote power source (a

circuit breaker panel, for example) in your equipment rack or facility. Cables

must be sized to meet the following criteria:

•

Rated for 60A service to allow for a fully loaded C150 system per NEC in the

United States or internationally, per local safety codes.

•

Limit voltage drop across the cable length to 0.5V or less.

Apply a coat of anti-oxidant paste to unplated metal contact

NOTE:

surfaces before you make the cable connections. File unplated connectors,

braided straps, and bus bars to a shiny finish. It is not necessary to file and

coat tinned, solder plated, or silver-plated connectors or other plated

connection surfaces, such as those on the PEM studs.

Step

Locate the chassis ground connector stud on the PEM front panel. It is

the single stud below the safety cover.

Apply a coat of anti-oxidant paste to the connector stud, if required.

Install the grounding cable. This cable is typically green or green and

yellow.

Replace the washer and nut on the stud.

Secure the nut with a nut driver or torque wrench (not to exceed 4

ft/lbs).

Connect the opposite end of the grounding cable to the appropriate

nearest grounding.
