2.4 Earth Ground Connection
The Reader 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 Reader 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.
