and Voltage
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.
Auto Range Select
The Auto Range Select function built into the 1200 Watt unit allows you to connect
to either low or high AC input voltages without making any adjustments to the unit.
We warrant that the unit will perform to specification at AC input voltage ranges 85
to 130 Vac and 190 to 264 Vac. See Table 2.2. Between these ranges (at 130 to
190 Vac), the unit will operate normally, although full performance to specification
cannot be guaranteed.
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.
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
!
CAUTION
When power switch is turned on, output voltage or current previously set will be
applied to loads.
!
CAUTION
To prevent damage to the power supply, turn off AC power to the unit before
changing from one AC input voltage range to another.
