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.
