Safety rules
When the batteries are connected to the UPS, the outlets may be energised even if the UPS is disconnected from the AC
input source.
Dangerous voltage levels are present within the UPS. It should be opened exclusively by qualified service
personnel.
The UPS must be properly earthed. Measurements are required to ensure that the total leakage current of the UPS
and the protected equipment does not exceed 3.5 mA.
Product safety
UPSs must be connected to a nearby wall outlet that is easily accessible.
The UPS can be disconnected from the AC-power source by removing the power cord.
◗
Never install the UPS near liquids or in an excessively damp environment.
◗
Never let a foreign body penetrate inside the UPS.
◗
Never block the ventilation grates of the UPS.
◗
Never expose the UPS to direct sunlight or a source of heat.
Special precautions
The UPS connection instructions contained in this manual must be followed in the indicated order.
Check that the indications on the rating plate correspond to your AC-power system and to the actual electrical consumption
of all the equipment to be connected to the UPS.
If the UPS must be stored prior to installation, storage must be in a dry place.
The admissible storage temperature range is -20
°
C to +45
°
C.
If the UPS remains de-energised for a long period, we recommend that you energise the UPS for a period of 48 hours, at
least once every month. This charges the battery, thus avoiding possible irreversible damage.
Prior to handling the battery:
◗
remove all watches, rings, bracelets and any other metal objects;
◗
use tools with insulated handles.
