Operational AC Input Voltage Ranges and Frequency
AC Fail LED
The AC Fail (ACF) LED turns on when the input voltage is outside
of the range specified for the power supply. The LED turns off when the input
voltage is within the range.
AC Input
Cord
The AC input cord we recommend is specified in Table 2.3, “AC Wire
Specification”. Add a non-locking plug suitable for use in the country in which you
are operating. If you require a special cord, call us.

AC Wire Specification
AC Input Wire
Connection
1. Strip the outside insulation on the AC cable approximately 4 in. (100 mm). Trim
the wires so that the ground wire is 0.5 in. (12 mm) longer than the other wires.
Strip 0.55" (14 mm) at the end of each of the wires. See Figure 2.2 detail (top).
2. 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.
