Possible cause
Loose parallel communication
cable or incorrect parallel
operation.
Remedy
For parallel system, make sure
parallel communication cable is
connected tightly and also
check if the PRA ID number is
right after turning on input
breakers one by one. If all the
number displays are correct,
it's ok to turn on UPSs after
disabling the warning message
by pressing 'UP' and 'DOWN'
button together. Otherwise,
please do NOT turn on UPSs
and contact your dealer for
help.
For single UPS, since there is
no communication cable and
parallel output cable
connection, simply ignore this
warning message by pressing
'UP' and 'DOWN' button to
disable and turning on UPS for
continuous operation.
