5. Storage and Maintenance
Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5 years
at 25°C ambient temperature) has been exceeded, the batteries must be replaced. In this
case, please contact your dealer.
Storage
Before storing, charge the UPS for minimum 5 hours. Store the UPS covered and upright in
a cool, dry location. During storage, recharge the battery in accordance with the following
table:
Storage Temperature
Recharge Frequency
Charging Duration
-25°C - 40°C
Every 3 months
1-2 hours
40°C - 45°C
Every 2 months
1-2 hours
Be sure to deliver the used battery to a recycling facility or ship it to your
dealer in the replacement battery packing material.

Never connect neutral line of input to neutral line of output. Otherwise, it will cause
the damage of the UPS. (see Figure 3)

l
Do not connect appliances or devices which would overload the UPS system to the
UPS output sockets.
l
Place cables in such a way that no one can step on or trip over them.
l
The UPS can be operated by any individuals with no previous experience.
l
Connect the UPS system only to an earthed shockproof outlet which must be easily
accessible and close to the UPS system.
l
Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of your
computer) to connect the UPS system to the building wiring outlet (shockproof
outlet).
l
Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS
system.
l
When installing the equipment, make sure the sum of the leakage current of the UPS
and the connected devices does not exceed 3.5mA.
1-4. Operation
l
Do not disconnect the mains cable on the UPS system or the building wiring outlet
(shockproof socket outlet) during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.
l
The UPS system features its own internal current source (batteries). The UPS output
sockets and output terminals block may be electrically live even if the UPS system is
not connected to the building wiring outlet.
l
In order to fully disconnect the UPS system, first press the OFF/Enter button to
disconnect the mains.
l
Prevent fluids and other foreign objects from entering the inside of the UPS system.
1-5. Maintenance, Service, and Faults
l
The UPS system operates with hazardous voltages. Repairs may be carried out only
by qualified maintenance personnel.
l
Caution - risk of electric shock. Even after the unit is disconnected from the mains
(building wiring outlet), components inside the UPS system are still connected to the
battery and electrically live and dangerous.
l
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.
l
Only persons adequately familiar with batteries and with the required precautionary
measures may replace batteries and supervise operations. Unauthorized persons
must be kept well away from the batteries.
