Chapter 3 Hardware Overview

Use only power wires of the required diameter for connecting the Switch to a power supply.

3.1.5.1 AC Power Connection

Connect the female end of the power cord to the power socket of your Switch. Connect the other end of the cord to a power outlet.

3.1.5.2 DC Power Connection

The Switch uses a single ETB series terminal block plug with four pins which allows you to connect up to two separate power supplies. If one power supply fails the system can operate on the remaining power supply. Use two wires to connect to a single terminal pair, one wire for the positive terminal and one wire for the negative terminal.

Note: The current rating of the power wires must be greater than 20 Amps. The power supply to which the Switch connects must have a built-in circuit breaker or switch to toggle the power.

Note: When installing the power wire, push it wire firmly into the terminal as deep as possible and make sure that no exposed (bare) wire can be seen or touched.

Exposed power wire is dangerous. Use extreme care when connecting a DC power source to the device.

To connect a power supply:

1Use a screwdriver to loosen the terminal block captive screws.

2Connect one end of a power wire to the Switch’s RTN (return) pin and tighten the captive screw.

3Connect the other end of the power wire to the positive terminal on the power supply.

4Connect one end of a power wire to the Switch’s -48V(input) pin and tighten the captive screw.

5Connect the other end of the power wire to the negative terminal on the power supply.

6Insert the terminal block plug in the Switch’s terminal block header.
