It is the intent of this document to provide guidance for wiring and board mounting of the CNI Battery Monitor. This accessory to the CNI product line adds utility by permitting the user to monitor the voltage level of the main supply. If this voltage level should drop below a defined point, then an alarm will be triggered, causing the CNI to call-in and report the event. Figure-1 illustrates the board layout of the CNI Battery Monitor.

Aside from the board itself, two additional parts are also included with the kit as shown in Figure-2.

Board Mounting & Wiring:
Figure-3 illustrates the proper mounting position for the board onto the enclosure boss. Only a single self-tapping screw is required for securing the board.

Wiring connections are straightforward with the green wire feeding into the alarm input on the CNI terminal block. To minimize wiring congestion, it is recommended that the red and black wires be routed underneath the CNI board as shown in Figures 3 & 4.
