CAUTION
If primary powers isolators are installed in other area from UPS area.
You must stick the following warning label on them.
“ISOLATE UNINTERRUPTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON
THIS CIRCUIT”
Dangerous voltage levels are present within the UPS. It should be opened
exclusively by qualified service personnel.
Warning, after the UPS shut-down, a dangerous voltage will be present on the
battery selector BCB.
The UPS must be properly earthed.
The battery supplied with the UPS contains small amounts of toxic materials.
To avoid accidents, the directives listed below must be observed.
w 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).
w Do not attempt to open the battery (the electrolyte is dangerous for the eyes
and skin).
w Comply with all applicable regulations for the disposal of the battery.
1.2.2 Product safety
A protection circuit breaker must be installed upstream and be easily accessible.
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 of the UPS.
Never expose the UPS to direct sunlight or a source of heat.
1.2.3 Special precautions
w The UPS connection instructions contained in this manual must be followed in the
indicated order.
w 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.
w If the UPS must be stored prior to installation, storage must be in a dry place.
w The admissible storage temperature range is -10° C to +45° C.
w If the UPS remains de-energised for a long period, we recommend that you
energise the UPS for a period of 24 hours, at least once every month. This charges the
battery, thus avoiding possible irreversible damage.
w The UPS is designed for normal climatic and environmental operating conditions as
defined in the "appendices" chapter: altitude, ambient operating temperature, relative
humidity and ambient transport and storage conditions.
w Using the UPS within the given limits guarantees its operation, but may affect the
service life of certain components, particularly that of the battery and its autonomy. The
maximum storage time of the UPS is limited due to the need to recharge its integrated
battery.
