4.1.3 Grounding Lugs
The CPSMC19xx-100 comes equipped with grounding lugs, which are provided for
a grounding conductor wire terminated with a two-hole, compression-type, ground-
ing connector. The grounding wire -- which must be a copper conductor -- is not
included with the chassis and must be provided by the customer/installer.
The electrical conducting path from the chassis must:
• Flow via the grounding lugs to the Common Bonding Network (CBN) for tele-
com installations; or to an alternate approved grounding system (if required) for
non-telecom installations,
• Be of sufficiently low impedance to conduct fault currents likely to be imposed
on the chassis, and
• Enable proper operation of any over-current protection devices.
The two-hole, compression-type, grounding connector must be fastened to the
grounding lugs with the enclosed, anti-rotation star-washers and lug-nut fasteners.
The required torque to the fasteners is specified by the connector’s manufacturer.
To properly ground the CPSMC19xx-100 chassis:
1. Obtain one (1) properly-terminated, grounding conductor (12 AWG copper
wire gauge or larger) with a two-hole, compression-type, grounding connector.
Note the manufacturer's applied torque that is required for the connector.
2. Attach the grounding conductor to the chassis by placing the two-hole, com-
pression-type connector onto the grounding lugs and fasten with appropriate
lock-washers and lug-nuts at the proper torque.
3. Attach the opposite end of the properly-terminated grounding conductor to the
Common Bonding Network (CBN) for telecom installations, or to an approved
grounding system (if required) for non-telecom installations.
