Measured value: ____
Vac
Measure the voltage between Neutral and Ground at the bypass input. The value should be
no greater than 2 Vac.
Use a calibrated voltmeter to measure the rectifier input voltages. Record the readings in the table below. Compare
your readings with the console display of the rectifier input voltage.
If the readings differ, the UPS’s input voltage
measurement may require calibration (
“Setup > Module config. > AC CALIBRATION”, or on touch screen “Main menu > Setup >
Modules > AC INPUT VOLTAGE CALIBRATION”
).

12. Input Isolation transformer
For UPS’s with an
input
isolation transformer: does the output of
each transformer phase within the expected range?
YES
NO
Perform a visual inspection of the interior and exterior of the input
transformer.
