Connecting the VX Encore to 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 degree C. An Alpha
Wire Company No. 45443. is an example of a suitable cable.
To connect the VX Encore to DC power:
1. Make sure the DC power is off.
2. Strip 2" of jacket material off the cable and 1/2" of insulation off each
wire.
3. Connect the _48V wire to the negative terminal using a small ßat-blade
screw driver to fasten the wire. See Figure 2-5.
4. Connect the ground wire to the positive terminal the same way.
5. The DSU/CSU is designed to operate with negative voltage, therefore, the
positive terminal is connected to ground.
WARNING: Observe caution when you connect the VX Encore to DC power. If you
connect it improperly, you may damage the DSU/CSU and/or harm yourself.
