Figure 4.1 illustrates the True On-Line Double Conversion architecture
of the UPS system. The major modules consist of:
1) An AC-to-DC power converter (rectifier) with PFC control circuit
2) A DC-to-AC high frequency inverter
3) An intelligent battery charger
4) A bank of stationary, maintenance-free batteries
5) A DC-to-DC push/pull converter control circuit
6) A static bypass loop
7) Input and output EMI filters

If the UPS malfunctions during operation please check that all lines are
connected properly and that the utility specifications are correct. Then
check the table below for solutions. Should the problem persist please
contact your local dealer for assistance.
Situation
Check Items
Solution
Fault LED
Read the error code
(see next page)
displayed by the
combination of LEDs,
and verify the fault as
follows.
1. Er05,Er39
1. Check for proper battery
connection. Measure battery
voltage to ensure that batteries
are charged and healthy.
Recharge batteries for 8 hours
if necessary. Simulate utility
outage to verify that UPS is
able to provide DC backup.
Otherwise consult your local
dealer right away.
2. Overload
2. Disconnect some non-critical
loads from the UPS output until
the overload ceases. Check if
there is any short circuit
between cables due to broken
cable
insulation. Replace the cables if
necessary.
3. Er11 (UPS Over
Temperature)
3. Remove any objects
obstructing the ventilation
louvers. Verify that the cooling
fans are working properly.
Contact your local dealer to
replace the fans if necessary.
4. Site wiring/Ground
fault
4. Check if the “L” and “N”
phases of the utility AC source
have been wrongly wired or if
the Ground- Neutral voltage
exceeds the
limits.

yourself. Contact your local
dealer for replacement.
6.Other error codes
6. Consult your local dealer for
assistance.
UPS fails to provide
battery backup or its
backup time is shorter
than its intended
performance.
If the backup time remains
unsatisfactory after 8 hours of
charging please contact your
local dealer for battery
replacement.
UPS is normal, but
there is no output to
the load.
Check that all power
cords are properly
connected.
If the problem persists consult
your local dealer for technical
assistance.
The UPS switches into
battery mode and then
back into utility mode
when a connected
device is turned on, or
the UPS
switches back and
forth between battery
and utility modes.
1. A power strip is
connected to the
UPS.
See if there is any
damage to the utility
wall receptacle or if
the cord plug is faulty.
1. Do not use the power strip.
2. Replace the wall
receptacle/cord plug.
Strange noise or smell
Immediately shut down the
whole system. Disconnect the
power from the UPS and call
for service
UPS is unable to
provide backup power.
Check that the battery
connectors are fully engaged.
Allow the batteries to recharge
if they are weak. If the problem
persists after recharging
replace the batteries. If the
problem still persists consult
your local dealer for technical
assistance.
Error Codes
When the Fault LED is lit press the ON button ‘ ’ briefly to check the
error code. The error codes 1, 2, 4, 8, and 16 are represented by the four
bar LEDs 25%, 50%, 75%, and 100%, and the Overload LED . Each
LED represents a number as shown in the figure below. For example, the
figure below shows the 25%, 50%, and 100% bar LEDs lit. The error code
is therefore 8 + 2 + 1 = 11, or Er11, which indicates that the UPS is over-
temperature.
