Connect Earth Ground to ACX710 Routers


To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be adequately grounded before power is connected.

You need a protective earthing terminal bracket for connecting the chassis to earth ground. This two-holed bracket is attached on the side of the chassis through the mounting rail, and provides a protective earthing terminal for the router. The grounding points are in the form of studs that are sized for M6 screws. (You need to provide these screws with integrated washers as we do not ship them in the accessory kit).

To ground the ACX710 router:

  1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the other end of the strap to an approved site ESD grounding point. See the instructions for your site.
  3. Ensure that all grounding surfaces are clean and are brought to a bright finish before you make grounding connections.
  4. Connect the grounding cable to a proper earth ground.
  5. Place the grounding cable lug over the grounding points on the side of the chassis (see Figure 1).

  6. Secure the grounding cable lug with the screws.
  7. Dress the grounding cable, and verify that it does not touch or block access to router components, and that it does not drape where people could trip on it.
  • Bare connectors and all grounding surfaces must be brought to a bright finish and coated with an antioxidant before crimp connections are made.

  • Non-conductive coatings on equipment that is to be bonded or grounded should be removed from threads and other contact surfaces to assure electrical continuity. To screw the box to its rack, use the thread-forming type unit mounting screws that remove any paint or non-conductive coatings to establish metal-to-metal contact.
