6.2 Wiring Terminal
6.2.1 2-Pin DC Power Terminal
Description
A 2-pin DC power cable consists of a 2-pin DC terminal block and power wires made onsite.
Make the power wires according to the power supply requirements and connect them to the
power supply system.
The 2-pin DC terminal block can prevent damages to the industrial switching router caused by
reverse connection of the power wires. Once the positive and negative wires are reversely
connected to power terminals, the industrial switching router will not be powered on.
The AR530 series and AR550 series use 2-pin DC power cables with different wire
sequences. Select the appropriate 2-pin DC power cable for the router you use.
