Severity Cause
 The fan monitoring
cable for the power
unit is not working
properly.
Critical The ready switch is OFF.
Critical  A load short-circuit
occurs.
 A short circuit occurs
inside the unit. (This
fault seldom occurs.)
Minor  The I2C bus is not
normal.
 The E2PROM is
faulty.
Minor The bypass waveform is
not normal.
Critical  The load is excessive.
 Derating reduces the
rated system power.
 The unit is damaged.
Minor  A large-power RCD
load is instantly
connected, or the
output load short-
circuits.
 The inverter bridge
short-circuits.
Minor  The load is excessive.
 Derating reduces the
rated system power.

B Alarm List
Solution
Close the ready switch.
1. Check load cable
distributions.
2. If load cable distributions
are normal, replace the
power unit.
1. Rectify the fault and check
whether the alarm is
cleared.
2. If the alarm is generated
again, replace the power
unit.

If not all units generate the
alarm, start the UPS,
transfer it to normal mode
and replace the faulty unit.
 If all units generate the
alarm, open the bypass
input circuit breaker. After
the inverter relay is closed,
close the bypass input
circuit breaker 10 seconds
later.
1. Check that there is no
overload.
2. Check that the unit power
is not derated due to a fan
fault.
3. If the alarm persists,
replace the power unit.
1. Check the load.
2. If the load is normal,
replace the power unit.
1. Check that there is no
overload.
