Step 2 Use a multimeter to measure the resistance between the NEG (-) and RTN (+) wiring terminal
sockets.
If the resistance is greater than or equal to 10 ohms, the power cables are connected properly.
If the resistance is less than 10 ohms, a short circuit is occurring. In this case, locate the cause
and reconnect the power cables to the wiring terminal sockets.
Step 3 Connect the other end of the power cables to the power supply device in the equipment room.
Step 4 Check the output voltage of the power supply device and turn on the power switch of the
device.
Step 5 Check whether the following conditions are met:

Connecting a Power Cable to an AC Power Module
The AC power module provides a power socket in the lower left corner of its front panel. The
power socket uses an International Electrotechnical Commission (IEC) C14 inlet and has a
power plug lock.
Step 1 Pull upward on the power plug lock on the left of the power socket, as shown in

The difference between the power supply device's output voltage and the voltage
between the RTN (+) and NEG (-) wiring terminal sockets is less than 2 V.
The power cables are correctly connected to positive and negative terminals of the power
module.
