Installation Using DC Power

You need a tray cable that is UL recognized 14 AWG, 3 conductors, copper strand wire, electrical power and control cable, type TC: tray cable, 600 V 90°C. Alpha Wire Company No. 45443 is an example.

To connect the Dual Trunk E1 Router to DC power:

1.Place the unit on a flat surface or tray.

2.Make sure the DC power source is off.

3.Before you connect the unit to the centralized DC power source, strip 2 inches of jacket material off the tray cable and 1/2 inch of insulation off each wire.

4.Connect the -48 V wire to the positive (+) terminal using a small flat screwdriver to fasten the wire.

5.Connect the ground wire to the negative (-) terminal using the same method.

The unit is designed to operate with negative voltage; therefore, the positive terminal is connected to ground.

6.Connect a properly grounded third wire to the ground stud near the terminal block using a 1/4 inch wrench and fastening torque of 5 inch-pounds.

7.To minimize disturbance to the wires through casual contact, secure the tray cable near the rack frame using multiple cable ties.

Use at least four cable ties, a minimum of 4 inches apart. The first tie should be within 6 inches of the terminal block.

8.Connect the Dual Trunk E1 Router to a DC power source. Turn on power source.

The LEDs on the front panel flash and status messages appear on the alphanumeric display as the Dual Trunk E1 Router runs the Self Test at power up.
