Detector Grounding - Prosense PC3 Series Installation And User Manual

Detector Grounding

Internal Ground connection: Each detector has grounding screw which utilizes grounding for
detector main PCB to detector body. The screw should be located correctly and fixed for all
times. In case of any maintenance activity this screw should be checked and fixed to make
sure for proper grounding.
External Ground Connection: It is recommended to utilize a No 14 AWG copper, (Stranded or
Solid), wire. Loosen the screw sufficiently to enable 'wrapping the wire around the screw in a
"U" shape. Raise the clamp and place the wire between the clamp and ground base, lower the
clamp and tighten the screw to 10.4lb-in torque.
