Connecting An Earth Ground - Irritrol IBOCPlus Guide D'utilisation

Note: Although the battery and the SPC-2 share the same input
terminals, only one power source can be connected to the IBOC
Plus at any given time. If using the SPC-2, connect the Orange
6-Volt (+) wire and Black negative (–) wire to the IBOC's battery
input terminals.

the rain sensor for additional information.

CONNECTING AN EARTH GROUND

A power surge is a sudden rise in voltage on the power main line. It is
then often followed by a drop in voltage as the power line equipment
tries to protect area users. A lightning strike on the power grid is the
most common cause of power surges and can be damaging to the
controller. Surge protection is built into the IBOC Plus terminal board
to help protect the controller from surge damage by shunting the
voltage to earth ground.
