Safety rules

Safety of persons

A UPS has its own internal power source (the battery). Consequently, the power outlets may be energized
even if the UPS is disconnected from the AC-power source.
Dangerous voltage levels are present within the UPS. It should be opened exclusively by qualified
service personnel.
The UPS must be properly earthed. If it is connected to the AC-power source via a wall outlet,
measurements are required to ensure that the total leakage current of the UPS and the protected
equipment does not exceed 3.5 mA. If the total leakage current exceeds this value, the INSTALL
version is mandatory and the earth wire must be connected to the input terminal block.
The battery supplied with the UPS contains small amounts of toxic materials. To avoid accidents,
the directives listed below must be observed.
Never operate the UPS if the ambient temperature and relative humidity are higher than the levels
specified in the documentation.
Never burn the battery (risk of explosion).
Do not attempt to open the battery (the electrolyte is dangerous for the eyes and skin).
Comply with all applicable regulations for the disposal of the battery.

Product safety

UPSs connected to the AC-power source via a wall outlet must remain in the immediate vicinity of the outlet.
The outlet must be easily accessible. For UPSs connected to the AC-power source via a terminal block,
a protection circuit breaker must be installed upstream and be easily accessible.
The UPS can be disconnected from the AC-power source by removing the power cord or the UPS
power cable.
Never install the UPS near liquids or in an excessively damp environment.
Never let a liquid or foreign body penetrate inside the UPS.
Never block the ventilation grates on the front or back 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 is positioned flat, check that not more than five modules are stacked on top of each other.
If the UPS must be stored prior to installation, storage must be in a dry place.
The admissible storage temperature range is -40° C to +50° C.
If the UPS remains de-energized for a long period, we recommend that you energize the UPS
for a period of 24 hours, at least once every month.
This charges the battery, thus avoiding possible irreversible damage.
