2.4.2 AC Sensor Connections
The ACM100 sensor connections are made by connecting to the 12-pin terminal strip on the
top of the unit. First, remove the four screws at the corners of the unit detaching the splash
guard from the unit. On the bottom of the splash guard, you will find a label detailing the wire
connection to pin number assignments, which are repeated in the table below.

WARNING: The voltages present on AC circuits can cause electrocution.
Before making any electrical connections to the ACM100, ensure that power is
removed from all AC circuits that will be connected to the ACM100. Only restore
AC power after all connections have been made to the ACM100 and the splash
guard has been re-installed.
