1.5.1 Establish a Ground Connection

CAUTION DO NOT operate your IPD40000E without a ground connection.

1.5.1.1 Connect a Ground Wire to the IPD4000E

Line up the 2-hole terminal lug of your ground wire with the two holes on the small, unpainted section on the back of your chassis. Secure the terminal lug to the chassis with two #10-32 screws.

1.5.1.2 Connect the Ground Wire to a Frame Ground

Ground wire connection can vary from location to location, although typically all equipment in a Central Office is grounded to a common copper bus.

1.5.2 Select a Terminal Block

Either terminal block on the back of the IPD4000E may be used to power the chassis; only one terminal block is required for operational purposes. The two terminal blocks on the IPD4000E are independent feeds. Chassis power is supplied by only one terminal block at a time; the second supply is merely back- up. Likewise, the two terminal blocks do not load-share. Each terminal block must be supplied with adequate Amps to run the chassis independently; power is not cumulative between the two.
