 To ground the Gateway or ATA:

1. Acquire a grounding cable of 18 AWG or greater gauge. For the PSTN Gateway, use the supplied grounding cable.

2. Locate the device near the building ground point, usually located at the electrical breaker box. The PSTN Gateway must

be within three feet (91.4 centimeters) of the building ground point.

3. Loosen the grounding terminal screw on the back of the device, as identified in Figure 18 and Figure 19.

4. Insert the end of the grounding cable under the grounding terminal.

5. Tighten the screw.

6. Connect the other end of the grounding cable to the building ground point, usually located at the electrical breaker box.
