Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Step 2 Turn off the DC power source at the circuit breaker, and tape the circuit breaker in the off position.
Step 3 On each DC input wire, use a wire stripping tool to strip not more than 0.35 inches (9 mm) of insulation
off the end of each wire (see Figure 3-12). The side on the Molex terminal block connector has a strip
gauge for 9 mm.

Step 4 Grasp the two-pin Molex terminal block and remove it from its mating connector on the power supply
unit. Move the Molex terminal block slightly back and forth horizontally to remove it from its mating
connector.
Step 5 Connect the two DC-input wires. Slide open the top of the connector to reveal the screw holes. Insert a
Number 2 Phillips screwdriver into the rectangular hole directly above the connector, push the wire fully
into the connector, and tighten the screw to 24 in-lb (2.7 N-m) torque with the screwdriver. The wires
should be connected in the following order:
a. Connect the return (reference) wire to the positive (+) terminal on the terminal block.
b. Connect the –48-V wire to the negative (–) terminal on the terminal block.
Note The color coding of the source DC power wire leads depends on the color coding of the site DC power
source. Typically, green or green and yellow indicates that the wire is a ground wire. Because there is no
color code standard for the source DC wiring, you must ensure that the power wires are connected to the
DC-input power supply terminal block in the proper positive (+) and negative (–) polarity.
In some cases, the source DC wire leads might have a positive (+) or negative (–) label. This is a
relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage
between the DC wire leads. When taking the measurement, the positive (+) lead and negative (–) lead
must always match the positive (+) and negative (–) labels on the DC power supply.
Caution No uninsulated part of the DC-input wire should be exposed.
Step 6 After the two input wires are connected to the Molex terminal block, plug the Molex terminal block
connector into the power connector located on the rear right-hand side of the appliance. (See location 5
in Figure 1-5 on page 1-9.)
Step 7 Connect the DC power input wires to the DC power source.
Step 8 If there is a second DC power supply, repeat Steps 3 to 7.
Step 9 After confirming that all installation steps are complete, continue with the installation of the network
and console cables. (See “Connecting the Network and Console Cables” section on page 3-18.)
