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.

Before carrying out any servicing and/or maintenance, disconnect the batteries and check that
there is no current and no hazardous voltage in the high capability capacitor 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!

Only replace the fuse with the same type and amperage in order to avoid fire hazards.

Do not dismantle the UPS system.

1-6. About batteries


It is recommended that a qualified technician change the battery.

Do not dispose of the battery in a fire as it may explode.

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 thoroughly with water and
clean dirtied 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 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 competent personnel who take the necessary
precautions. Keep unauthorized personnel away from batteries.
