To avoid malfunctions, if these products are not installed into a grounded

metal electrical box, ground the metal faceplates in one of two ways:

1. Ground each faceplate directly to

an earth ground. Or...

2. Tie each faceplate to its circuit

board ground via a ground pin on
one of the connectors. Refer to the
product’s manual to determine the
correct circuit ground pin.

Do not tie a product’s faceplate

to both a separate earth ground
and the circuit ground (via a
connector pin). If you tie a product to two
different ground sources, you may intro­duce ground loops or other ground
related problems into the system.

Do not tie a faceplate to a product’s circuit

ground if the product will be installed in a
grounded metal electrical box.

Grounding is not required for plastic faceplates.
