26 Connecting Interface Cables to a Device
Connecting Interface Cables to a Device
To connect interface cables to a device, perform the following steps:
1. Have ready a length of the type of cable used by the interface.
2. Insert the cable connector into the cable-connector port on the interface
faceplate.
3. Arrange the cable as follows to prevent it from dislodging or developing stress
points:
a. Secure the cable so that it is not supporting its own weight as it hangs to
the floor.
b. Place excess cable out of the way in a neatly coiled loop.
c. Use fasteners to maintain the shape of cable loops.
Chassis Grounding
To meet safety and electromagnetic interference (EMI) requirements, and to ensure
proper operation, the device must be adequately grounded before power is
connected. A two-hole grounding lug is provided on the rear of the chassis to
connect the device to earth ground (see Figure 13 on page 20).
The grounding cable must be American Wire Gauge (AWG) number-14
single-strand wire cable and must be able to handle up to 6 ampere (A).
To ground the device before connecting power, you connect the grounding cable to
earth ground and then attach the cable to the lug on the rear of the chassis.
Connecting the Power
This section provides instructions for connecting AC and DC power to a device.
AC Power
The AC power cord shipped with the device connects the device to earth ground
when plugged into an AC grounding-type power outlet. The device must be
connected to earth ground during normal operation.
To connect AC power to the device, perform the following steps:
1. Locate the power cord or cords shipped with the device, which has a plug
appropriate for your geographical location.
CAUTION: Before device installation begins, a licensed electrician must attach a
cable lug to the grounding cable that you supply. A cable with an incorrectly
attached lug can damage the device (for example, by causing a short circuit).
