2.4 Operation
1. Do not disconnect the mains cable on the UPS system or the building wiring
socket outlet during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.
2. The UPS has its own internal power source (batteries). The output terminals
may be live even when the UPS is not connected to the AC supply.
3. Ensure that no fluids or other foreign objects can enter the UPS system.
2.5 Maintenance and Service
1. Caution - risk of electric shock.
Even after the unit is disconnected from the mains power supply (building
wiring socket outlet), components inside the UPS system are still connected
to the battery and are still electrically live and dangerous. Before carrying out
any kind of servicing and/or maintenance, disconnect the batteries and verify
that no current is present.
2. Only persons adequately familiar with batteries and with the required
precautionary measures may exchange batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
3. Batteries may cause electric shock and have a high short-circuit current.
Please take the precautionary measures specified below and any other
measures necessary when working with batteries:
- remove wristwatches, rings and other metal objects
- use only tools with insulated grips and handles.
4. When changing batteries, install the same number and same type of
batteries.
5. Do not attempt to dispose of batteries by burning them. This could cause
battery explosion.
6. Do not open or destroy batteries. Escaping electrolyte can cause injury to
the skin and eyes.

3.1 Inspection
1. The system may be installed and wired only by qualified electricians in
accordance with applicable safety regulations.
2. When installing the electrical wiring, please note the nominal amperage of
your incoming feeder.
3. Inspect the packaging carton and its contents for damage. Please inform
the transport agency immediately should you find signs of damage.
Please keep the packaging in a safe place for future use.
4. Please ensure that the incoming feeder is isolated and secured to prevent
it from being switched back on again.
3.2 Connection

If the UPS is connected via the power cord, please use a proper socket with
protection against electric current, and pay attention to the capacity of the
socket.
2. UPS Output Connection
The output of this model is with socket-types only (NEMA or IEC). Simply plug
