Grounding - backplate only - AWS810

Cable cutters Cable stripper

WARNING When installing the backplate without the enclosure, ground the backplate to the local grounding connector with a low impedance connection. Vaisala recommends 6 mm2 (10 AWG) or heavier copper wire.

WARNING A long cable between units (sensors, transmitters, power supplies, and displays) can cause a lethal lightning-induced current surge. Always ground the enclosure to a suitable grounded location with a short, low-resistance cable.

1. Connect the grounding cable to the grounding point located at the bottom of the backplate.

   

2. Strip a 10 … 15-mm (0.39 ... 0.59 in) sheath from the cable end and solder it, or use a cable ferrule.
3. Connect the other end of the cable to a suitable grounded location using an applicable adapter, cable lug, or similar.
