The AC input cord we recommend is specified in the table below. Add a non-locking
plug suitable for use in the country in which you are operating. If you require a
special cord, please contact the manufacturer.
AC Input Wire
Connection
The power supply is shipped with a protective cover for the AC input connector. As
long as the screw-holes on the AC input cover and the standoffs on the unit align, the
cover may be installed at any orientation. To prepare and connect the AC input
wiring, follow these steps:
1. Use a gloved finger or a blunt tool to push in the circular knockout on the cover
that is preferred for your system setup. After you push in the knockout, twist it
until it detaches from the cover, and throw it away.
2. Strip the outside insulation on the AC cable approximately 2 in. (5 cm). Strip
0.25 in. (6 mm) at the end of each of the wires. See Figure 2.2, on page 34 for
details.
3. Unscrew the base of the strain relief from the helix-shaped body. Insert the base
through the outside opening in the AC input cover and, from the inside, screw
the locknut securely onto the base.
4. Slide the helix-shaped body onto the AC cable. Insert the stripped wires through
the strain relief base until the outer cable jacket is flush with the edge of the base.
Tighten the body to the base while holding the cable in place. The cable is now
securely fastened inside the strain relief.
5. Route the AC wires to the input connector terminals as required. For input
connector terminal locations, see the label on the rear panel of the unit and Table
2.2, on page 34 . To connect the wiring, loosen the terminal screw, insert the
stripped wire into the terminal, and tighten the screw securely.
