3.4. Input Wiring
The AC Source is designed to work from a single utility supply. The IEC 320 input connector
will accept a standard IEC line cord with the appropriate mating connector for the utility outlet.
The utility outlet must be properly grounded and be capable of supplying at least 1725 VA at
120V to 240V in order to deliver full output power in the 1251RP.
Note: When using less than 120 V line input, the 1251RP should be used at no more
than 1000 VA output power to limit the input line current to less than 15A.

3.5.1. Output Wiring
Front Panel
When the low voltage range is selected, only the single US NEMA 5-15R output socket will
be active. If the high voltage range is selected, only the European CEE7/7 socket will be
active.
Either voltage will be present on the output terminals at the rear panel. There is only one
output terminal on the rear panel marked HIGH and LOW. This output carries the output of
the AC Source in both high and low voltage range. The HIGH and LOW label on the rear
panel refer to output high side and output low side (return) respectively, not to the voltage
range selected.
Note: Do not connect these outputs together as this will cause the unit to fault.
