2.5 AC Input Power Connection
WARNING
Ensure the power supply is connected to a grounded AC outlet with the
recommended AC input connector configured for the available line voltage
as set out in this section. There is a 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.
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.
2.5.1 AC Input Connector and Voltage Selection
The AC input connector is a 3-terminal wire clamp located on the power supply's rear panel. See
Figure 2.5-1.
Auto Range Select
CAUTION
To prevent damage to the power supply, turn off AC power to the unit before
changing from one AC input power range to another.
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 130Vac and 190 to 264Vac. See Table 2.5-1. Between these ranges (at 130 to
190Vac), the unit will operate normally, although full performance to specification cannot be guaranteed.
Table 2.5-1 AC Input Voltage Ranges and Frequency
AC Voltage Range Frequency
85-130Vac 1 1 (20A maximum at 120Vac) 47-63Hz
190-264Vac 1 1 (10A maximum at 230Vac) 47-63Hz
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 goes off when the input voltage is within the range.
2.5.2 AC Input Cord
The AC input cord we recommend is specified in Table 2.5-2. Add a plug suitable for use in the country in
which you are operating. If you require a special cord, call us.
