Powering On a DC Powered Chassis
This section describes how to power on a DC powered AT-CV5000 chassis.
Warning
As a safety precaution, a 15 Amp circuit breaker should be installed at
the supply end of the cable to be used with this LAN equipment.
ALWAYS connect the wiring to the LAN equipment first before
connecting the wiring to the breaker. To avoid the danger of physical
injury from electrical shock, do not work with HOT feeds. Always be
sure that the breaker is in the OFF position before connecting the wiring
to the breaker.
Note
A tray cable is required to connect the power source if the chassis is
powered by centralized DC power. The tray cable must be an UL listed
Type TC tray cable and rated at 600 V and 90 degree C, with three
conductors, minimum 14 AWG.
1. Make sure that the ON/OFF power switch is in the OFF position.
2. Locate the two DC terminal blocks, labeled A and B, on the rear panel of
the chassis.
3. Starting from the left side of a terminal block, identify the positive, power
supply ground and negative terminals using the symbols below the
terminal block in Figure 6.
Figure 6. DC Terminal Block
4. With a 14-gauge wire-stripping tool, strip the three wires in the tray cable
coming from the DC input power source to 8mm ± 1mm (0.31 in., ± 0.039
in.), as shown in Figure 7.

40-60VDC
Warning
Do not strip more than the recommended amount of wire. Stripping
more than the recommended amount can create a safety hazard by
leaving exposed wire on the terminal block after installation.
Figure 7. Stripped Wire
5. Connect the power supply ground wire into the middle of the three
terminals; this is the terminal marked with the ground symbol. Inserting the
wire into the terminal and tightening the connection with a flathead
screwdriver, as shown in Figure 8.
Warning
When installing this equipment, always ensure that the power supply
ground connection is installed first and disconnected last.

6. Connect the +48 VDC (RTN) feed wire to the terminal block marked
+ (plus).
7. Connect the -48 VDC feed wire to the terminal block marked - (minus).
