Connecting to a Power Source
The switch can be powered by two power supplies (input range 12 to 48 V DC). Insert the
positive and negative wires (AWG 14-26) into V+ and V- contact on the terminal block and
tighten the wire-clamp screws to prevent the wires from being loosened.
Alarm Relay Connecting
The alarm relay output contacts are in the middle of the DC terminal block connector
shown as the figure below. By inserting the wires, the relay output alarm will detect any
port failures, and form a short circuit. The alarm relay out is “Normal Open”.
