E1200i TeraScale and ExaScale DC Chassis Ground

Step Task

1 Locate the chassis ground connector nuts on the rear of the chassis.

2 Install the grounding cables to the ground nuts. The grounding cable

must comply with your local electrical codes in size and color (typically

the color is green or green with yellow stripe).

NOTE: Grounding cables must be terminated only with a UL-

listed 2-hole lug with 1/4-inch holes on 3/4-inch spacing.

Cable Connector Required for E1200i AC

Use ANSI UNC 1/4-20 x 12 bolt.

4 Tighten the bolt (torque should not exceed 25 inch/lbs).

5 Connect the opposite end of the grounding cable to the nearest

appropriate facility grounding post.

Step Task

1 Remove one outer nut and one washer from each of the six studs. One

nut should remain, tight on the stud. If the inner nut is loose, re-tighten it

to 25 inch/lbs, maximum.

Locate the chassis ground connector studs on the PEM front panel. The

two rightmost studs are the ground connection.
