TCX1000-RDM20 Chassis Grounding Cable and Lug Specifications
For installations that require a separate grounding conductor to the chassis, the
TCX1000-RDM20 must be adequately grounded before power is connected to ensure
proper operation and to meet safety and electromagnetic interference (EMI) requirements.
To ground a TCX1000-RDM20, connect a grounding cable to earth ground and then
attach it to the chassis grounding points.
WARNING: The device is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
provided on the chassis in addition to the grounding pin of the power supply
cord. This separate protective earthing terminal must be permanently
connected to earth ground for installations that require a separate grounding
conductor to the chassis.
CAUTION: Before device installation begins, a licensed electrician must
attach a cable lug to the grounding cables that you supply. See “Connecting
the TCX1000-RDM20 Grounding Cable” on page 70 . A cable with an
incorrectly attached lug can damage the TCX1000-RDM20.
Before connecting the TCX1000-RDM20 to earth ground, review the following information:
• A protective earthing terminal bracket is required for connecting the TCX1000-RDM20
to earth ground. This bracket is attached to the rear of the TCX1000-RDM20 chassis
and provides a protective earthing terminal for the device. The grounding points require
two #10-32 UNF screws. The grounding points are spaced at 0.63 in. (16 mm).
• The grounding lug required is a Panduit LCA10-10F-L or equivalent (provided). The
grounding lug accommodates 14–10 AWG (2–5.3 mm²) stranded wire (not provided).
•
The grounding cable that you provide for a TCX1000-RDM20 must be the same size
or heavier than the input wire of each power supply. Minimum recommendations are
14–10 AWG (2–5.3 mm²) stranded wire, 60° C wire, or as permitted by local code.
