Wiring the Power Input
Connector

The input power connector, provided with the barrier, is
field-wireable with screw terminals.

Wiring the Power Output
Connectors

The output connectors all have power on pin 2. Pins 1,
3, and 5 are all connected to ground. Pins 4 and 6 are
not connected. NOTE: If you are making your own cable
connections, the wire colors may differ.

Use a Class 2 Power Supply only.
