Ground Connection
CAUTION:
• Proper grounding (connection to ground) is very important to reduce the risk of elec-
trocution to the user or protect the PBX from bad effects of external noise in case of a
lightning strike.
• A permanent connection between ground and the ground terminal of the PBX must be
made.
1. Tighten the provided screw stud into the Grounding port on PBX.
2. Insert an 18AWG grounding wire (user supplied).
3. Tighten the provided screw nut.
4. Attach the grounding wire to the grounding terminal.
