Issue 02 (2020-01-10)
Cause
 The fan
monitoring cable
is faulty.
Critical The ready switch is
OFF.
Critical  A load short-
circuit occurs.
 A short circuit
occurs inside the
module. (This
fault seldom
occurs.)
 The output is
incorrectly
grounded.
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 module is
damaged.
 The output is
incorrectly
grounded.
Minor  A large-power
RCD load is
instantly
connected, or the
output load short-
circuits.

Solution
2. Check the fan monitoring cable.
Close the ready switch.
1. Check load cable distributions.
2. Check whether the output is
grounded.
3. If the load cable connections are
normal and the output is correctly
grounded, replace the power unit
or module.
1. Rectify the fault and check
whether the alarm is cleared.
2. If the alarm is generated again,
replace the power module.
 If not all modules generate the
alarm, start the UPS, transfer it to
normal mode, and replace the
faulty module.
 If all modules 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 module power is
not derated due to a fan fault.
3. Check whether the power grid has
a large asymmetric load.
4. Check whether the output is
grounded.
5. If the alarm persists, replace the
power module.
1. Check the load.
2. If the load is normal, replace the
power module.
