CHAPTER 3 INSTALLATION PROCEDURE
1. PRECAUTIONS
1.1 Grounding Requirements
The system grounding must have a specific ground resistance and AC noise level, and is to be connected to a pre-
determined terminal in the PBX. Standard grounding requirements are as follows:
• Communication grounding: Less than 10 ohm
• Protective ground for PIM: Less than 10 ohm
Note :The AC ripple on these various grounds should be less than 0.5 Vp-p.
CAUTION:
Grounding circuit continuity is vital for safe operation of telecommunication equipment. Never
operate this equipment with the grounding conductor disconnected.
