The display will sequence to the first summary screen indicating the following input and output
information: frequency, voltage, current, and apparent power. The screen also includes the unit
status (OK, WARNING, or FAILURE) and operating range (1:1, BOOST1, BOOST2 or
BOOST3).
Verify that the input voltage and frequency are displayed are the expected values. Also, ensure
that the load is within the unit ratings. Monitor the input voltage and current levels with load
applied. Refer to published rating curves for maximum current, kVA and kW levels.
NOTE:
It is normal under no load conditions to have up to 2 Amps of input current flowing.
This current does not degrade the unit power rating.
After 5 seconds the display will sequence to the second summary screen indicating the following
input and output information: frequency, real power, power factor, and load level.
The display will continue alternating between the two summary screens every 5 seconds.
