Selection
The AC input connector is a 3-terminal wire clamp located on the power supply’s
rear panel. See Figure 2.2 AC Input Cover and Strain Relief. See Table 2.2 for the
input voltage ranges and frequency required to operate the power supply.
Table 2.2 Operation AC Input Voltage Range 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.

WARNING
There is a potential shock hazard if the power supply chassis and cover are not
connected to an electrical ground via the safety ground in the AC input
connector. Ensure that the power supply is connected to a grounded AC outlet
with the recommended AC input connector configured for the available line
voltage as described in this section.
WARNING
Disconnect AC power from the unit before removing the cover. Even with the
front panel power switch in the OFF position, live line voltages are exposed
when the cover is removed. Repairs must be made by experienced service
technicians only.
!
CAUTION
When power switch is turned on, output voltage or current previously set will be
applied to loads.
