TCX1000 Programmable ROADM Hardware Guide
Connecting the TCX1000-RDM20 Grounding Cable
70
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to earth ground before you connect it to
power. For installations that require a separate grounding conductor to the chassis, use
the protective earthing terminal on the TCX1000-RDM20 chassis to connect to the earth
ground.
NOTE:
An AC-powered TCX1000-RDM20 gains additional grounding when
you plug the power supply in the device into a grounded AC power outlet by
using an AC power cord appropriate for your geographical location.
CAUTION:
Before you connect power to the TCX1000-RDM20, a licensed
electrician must attach a cable lug to the grounding and power cables that
you supply. A cable with an incorrectly attached lug can damage the
TCX1000-RDM20 (for example, by causing a short circuit).
NOTE:
Mount the TCX1000-RDM20 in the rack or cabinet before attaching
the grounding lug to the TCX1000-RDM20.
Ensure that you have the following parts and tools available:
NOTE:
The grounding point is located on the back of the TCX1000-RDM20
and is a #10-32 threaded stud.
Grounding lug—Panduit LCA10-10F-L (provided) that accommodates 14-10 AWG
standard wire (not provided).
Two #10 external tooth lock washers and one #10 hex nut (provided).
Screwdriver appropriate for the screws (not provided).
Electrostatic discharge (ESD) grounding wrist strap (not provided).
To connect a grounding cable to the TCX1000-RDM20:
Attach an ESD grounding strap to your bare wrist, and connect the strap to an approved
1.
site ESD grounding point. See the instructions for your site.
Connect one end of the grounding cable to a proper site earth ground, such as the
2.
rack in which the TCX1000-RDM20 is mounted.
