Grounding Lugs
The CPSMC18xx-xxx comes equipped with grounding lugs, which are provided for
a grounding conductor wire terminated with a
two-hole, compression-type,
grounding 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
telecom 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 CPSMC18xx-xxx 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,
compression-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.
