Connecting to a Power Source

The switch can be powered by two power supplies (input range 12 to 58 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 and set the DIP switch of the respective
Port Alarm to "ON", the relay output alarm will detect any port failures, and form a short
circuit. The alarm relay out is "Normal Open".
