Grounding the
PCVT-48VDC-53VDC
The PCVT-48VDC-53VDC comes equipped with grounding lugs located on the back panel. They require
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 PCVT-48VDC-53VDC
and must be provided by the customer/installer.
The electrical conducting path from the PCVT-48VDC-53VDC must:
Flow via the grounding lugs to the common bonding network (CBN) for telecom installations, or to an
alternative approved grounding system (if required) for non-telecom installations.
Be of sufficiently low impedance to conduct fault currents likely to be imposed on the PCVT-48VDC-
53VDC, and
Enable proper operation of any over-current protection devices.
The conductor may be fastened to the grounding lugs with the enclosed antirotation star-washers and
lug-nut fasteners. The applied torque required to the connector lug-nut fasteners is specified by the
connector’s manufacturer (4-5 inch-pounds typical or “recommended”). See the
more details.
