by electrostatic discharge (ESD) if
they are not grounded
correctly.
(See the other side.)

Grounding Extron Architectural Product Faceplates
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.
N 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 intro-
duce ground loops or other grounding-
related problems into the system.
N Do not tie a faceplate to a product’s circuit
ground if the product will be installed in a
grounded metal electrical box.
N Grounding is not required for plastic faceplates.
