5. Storage and maintenance
5-1. Storage
Charge the UPS for at least 7 hours before storing the unit. Cover the UPS, and place it upright in a cool, dry location. During
storage, recharge the battery in accordance with the following table:
5-2. Maintenance
The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel.
Even after the unit is disconnected from the mains, components inside the UPS system are still connected to the battery
packs which are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current is present and
no hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and the required
precautions. Keep unauthorized personnel away from batteries.
Verify that no voltage between the battery terminals and the ground is present before maintenance or repair. In this product,
the battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the
ground.
A battery can present a risk of electric shock and high short circuit current. The following precaution should be observed
when working on batteries:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
Replace batteries with the same type and number of units.
Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The batteries must be properly
deposed according to local regulation.
Do not open or destroy batteries. Released electrolyte is highly poisonous and harmful to the skin and eyes.
Replace the fuse only with the same type and amperage in order to avoid fire hazards.
Do not disassemble the UPS system.

Even though the mains supply is normal,
and there are no status indicators or
alarms.
The icon and the warning code blink
on the LCD display and the alarm starts
beeping once every second.
The and icons blink on the LCD
display and the alarm starts beeping once
every second.
The and icons blink on the LCD
display and the alarm beeps twice every

Fault code 43 becomes illuminated along
with the icon on the LCD display,
and the alarm starts beeping continuously.
Fault code 14 becomes illuminated along
with the icon on the LCD display,
and the alarm starts beeping continuously.
Fault codes 01, 02, 03, 04, 11, 12, 13,
14,1A, 21, 24, 35, 36, 41, 42 or 43 become
illuminated on the LCD display, and the
alarm starts beeping continuously.
Battery backup time is shorter than its
nominal value.
The and icons become illuminated
on the LCD display, and the alarm starts
beeping once every second.
The AC input power is not properly
connected.
EPO function is enabled.
The external or internal battery is
incorrectly connected.
UPS is overloaded.
UPS is overloaded. Devices connected to
the UPS are fed directly by the electrical
network via the bypass.
After repetitive overloads, the UPS is
locked in the Bypass mode. Connected
devices are fed directly by the mains.
The UPS shuts down automatically upon
detecting an overload on the UPS output.
The UPS shuts down automatically upon
detecting a short circuit on the UPS
output.
A UPS internal fault has occurred. There
are two possible causes:
1. Power is continued to be supplied to
the load, but is done directly from the AC
grid via a bypass.
2. Power is no longer supplied to the load.
Batteries are not fully charged.
Defective batteries.
Fan is either locked, has stopped
working, or the UPS temperature is too
high.
Check to make sure the power cord is
firmly connected to an AC wall socket.
Set the circuit in closed position to
disable EPO function.
Check if all batteries are properly
connected.
Remove excess loads from the UPS
output.
Remove excess loads from the UPS
output.
Remove excess loads from UPS output
first. Then shut down the UPS and restart
it.
Remove excess loads from the UPS
output and restart the unit once again.
Check the output wiring and if the
connected devices are short-circuited.
Please contact the dealer or service
center.
Charge the batteries for at least 7 hours
and then check their capacity. If the
problem still persists, consult your dealer.
Contact your dealer for a replacement.
Check fans and notify dealer.
