Connecting the TCX1000-RDM20 Grounding Cable


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.


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.


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).


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:


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:

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
  2. Connect one end of the grounding cable to a proper site earth ground, such as the rack in which the TCX1000-RDM20 is mounted.
  3. Strip the appropriate length of wire for the ground lug type used, and verify that a licensed electrician has attached the cable lug provided with the TCX1000-RDM20 to the grounding cable.
  4. Attach the grounding lug, lock washers, and hex nut as shown in Figure 1.

  5. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.
