Connect to AC/HVAC/HVDC Power

You must install the PTX12008 in a restricted-access location and ensure that the chassis is always properly grounded. The PTX12008 has a two-hole protective grounding terminal on the upper right corner of the rear panel of the chassis. Under all circumstances, use this grounding terminal to ground the chassis. For AC/HVAC/HVDC-powered systems, you must also use the grounding wire in the power cord along with the two-hole grounding connection. This tested system of using the grounding wire along with the two-hole protective grounding terminal meets or exceeds all applicable EMC regulatory requirements.

Before you connect the protective grounding terminal on the router to an earth ground, ensure that a licensed electrician attaches an appropriate grounding terminal to the grounding cable you supply. Using a grounding cable with an incorrectly attached terminal lug can damage the router.

To connect the PTX12008 to AC/HVAC/HVDC power, you must do the following:

Ground the PTX12008 Router

To ground the PTX12008:

  1. Verify that a licensed electrician has attached the protective grounding terminal lug provided to the grounding cable.

  2. Connect the other end of the grounding cable to a proper earth ground.

  3. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to the ESD point on the rear panel of the chassis.
