5-1. Storage
Before storing, charge the UPS for at least 7 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
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.
Only trained battery engineers who understand the required precautionary measures may replace
batteries and supervise operations.
Verify that no voltage between the battery terminals and the ground is present before
maintenance or repair. The UPS has a centre tapped battery that is connected to Neutral. Hazardous
voltages may occur between the battery terminals and the grounding/ earthing.
Batteries may cause electric shock and have a high short-circuit current. Please remove all
wristwatches, rings and other metal objects before maintenance or repair, and only use tools with
insulated grips and handles for maintaining or repairing.
When replace the batteries, install the same number and same type of batteries.
Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The
batteries must be deposed of according to local environmental regulations.
Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may
be toxic.
Please replace the fuse only with the same type and amperage in order to avoid fire hazards.
Do not disassemble the UPS system.
