3.2 Hardware Installation
3.2.1 Wiring the DC Power Inputs
Before installing the power input, make sure the DC power supply complies with standard power supply certifications.
NOTE: Suitable wire gauge is from 12 to 24 AWG.
Follow these steps to wire the DC power cable to the connector:
1. Insert the positive and negative wires into the V+ and V- contacts on the terminal block connector.
2. Tighten the wire clamp screws to prevent the DC wires from loosening.

3.2.2 Wiring the Alarm Relay
The switch provides one dry relay output for a power or port link event. The alarm relay default is “open” and forms a closed
circuit when the event occurs. The relay conductor has a maximum of 24 Watts. When it connects with a 24-VDC power source,
the maximum current is 1 Amp. The following diagram shows how to create an alarm circuit.
WARNING: Do not connect to AC line.
