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 pos-
itive terminal and one wire for the negative terminal.
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.
WARNING:
Exposed power wire is dangerous. Use extreme care when connecting a DC power source to the device.
To connect a power supply:
1. Use a screwdriver to loosen the terminal block captive screws.
2. Connect one end of a power wire to the switch's RTN (return) pin and tighten the captive screw.
3. Connect the other end of the power wire to the positive terminal on the power supply.
4. Connect one end of a power wire to the switch's -48V (input) pin and tighten the captive screw.
5. Connect the other end of the power wire to the negative terminal on the power supply.
6. Insert the terminal block plug in the switch's terminal block header.
