3.6 System Grounding
Both the PI source and the remote have internal surge suppression devices, which shunt
common mode power surge power that may be induced in the hybrid cable to ground. Transient
voltage suppression is part of the circuit, but the base plates at both ends of a circuit must
be grounded to facilitate surge voltage protection. Proper installation ensures that the surge
suppression will operate as intended.
The installer must mount the OneReach units such that the base plates are connected to local
ground. This is done by using grounding screws (not supplied) to secure the metal base of the
PI source or remote to a mounting plate connected to an approved ground.
If the PI source or remote cannot be connected directly to a grounded plate, a ground wire with
grounding lug (not supplied) must be used. The ground lug and wire must be installed between
the base plate and the ground screw, and tightened securely. The other end of the ground wire
is connected to an approved earth ground. Use a copper ground wire, minimum 12AWG
(not supplied). Be sure the OneReach system is properly grounded prior to applying power.
