Earth Ground Connection
The Analog Output Expander has a connection for earth ground. For best results a cold water pipe should be
used with a pipe wiring clamp. If a cold water pipe is not available, connect to a suitable ground connection in
the installation. A minimum 14AWG solid copper wire shall be used from the Analog Output Expander's earth
connection point to the clamp on the cold water pipe. If other earth clamps are present at the same connection
point connect the clamp below the existing units.
