There are 2 terminal blocks, each with it’s own reference terminal. This allows for 2 different
types of circuits to be monitored, from 24 to 120 volts ac or dc. An example pull sheet is
included with this document.
To monitor low voltage circuits (below 60 volts) a jumper is installed on a 2 pin header in front
of the wire terminal.
To install the device, simply fasten to the box to the cartop with screws through the mounting
flanges on the outside of the box.
