Grounding the Switch

This section provides instructions for grounding the switch.

Normally, the functional grounding of the switch is achieved through the DC input connection. If you would like to do additional grounding, follow the instructions below:

Figure 1. Grounding the Switch
 

1

Screw M4 (with washer)

2

Solder terminal lug (loop ring lug)

Grounding point
Note: Grounding wires and grounding lugs are not supplied with the product. The wire size should meet local and national installation requirements.
Note: The earth connection must not be removed unless all supply connections are disconnected.
  1. Ensure the rack is properly grounded and is in compliance with ETSI ETS 300 253.
  2. Verify that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment).
  3. Attach the solder terminal lug (not provided with the switch) to an 18 AWG minimum grounding wire (not provided with the switch), and connect it to the grounding point on the rear panel of the switch.
  4. Tighten the M4 screw to secure the lug to the grounding point.
  5. Connect the other end of the wire to the nearby grounded surface.
