1-4. Operation

Never disconnect the ground conductor cable on the UPS or the building wiring terminals as this

would cancel the protective ground of the UPS system and to all connected loads.
The UPS system features its own, internal current supply (batteries). The UPS output sockets or

output terminal blocks may be electrically live even if the UPS system is not connected to the
mains outlet.
In order to fully disconnect the UPS system, first press the "OFF" button and then disconnect the

mains.
Ensure that no liquid or other foreign objects can enter the UPS system.


1-5. Maintenance, servicing and faults

The UPS system operates with hazardous voltages. Repairs may only be carried out by qualified

maintenance personnel.
Caution - Risk of electric shock. Even after the unit is disconnected from the mains (mains outlet)
components inside the UPS system are still connected to the battery and electrically live and
dangerous.

terminals such as BUS-capacitors.
Only people who are familiar with batteries and with the required precautionary measures may

replace the batteries and supervise operations. Unauthorized persons must be kept well away
from the batteries.
Caution - Risk of electric shock. The battery circuit is not isolated from the input voltage. Hazardous
voltages may occur between the battery terminals and the ground. Before touching, please check that
no voltage is present!

Do not dismantle the UPS system.


1-6. About batteries:

It is recommended that a qualified technician changes the battery.

Do not open or damage the battery! The electrolyte, fundamentally sulphuric acid, can be toxic

and harmful to the skin and eyes. If you come into contact with it, wash the affected body parts
thoroughly with water and clean the soiled clothes.
Do not throw the battery into a fire. It may explode. It has to be disposed of separately at the end

of its useful life. Refer to the local legislation and regulations.
The UPS contains large-capacity batteries. To avoid any danger of electric shock do not open

it/them. If a battery needs servicing or has to be replaced, please contact the distributor.
Servicing should be performed or supervised by able personnel who will take the necessary

precautions. Keep unauthorized personnel away from batteries.
