The 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. Measurements are required to ensure
that the total leakage current of the UPS and the protected equipment
does not exceed 3.5mA by checking their characteristics.
The battery supplied with the UPS contains small amounts of toxic materials. To avoid
accidents, the directives listed below must be observed:
- 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.
- Batteries constitute a danger (electrical shock, burns). The short-circuit current may be
very high. Precautions must be taken for all handing: remove watches, rings, bracelets
and any other metal objects, use tools with insulated handles.
Product Safety
The UPS connection instructions and operation described in the manual must be followed
in the indicated order.
UPS 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.
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.
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.
If the UPS must be stored prior to installation, storage must be in a dry place.
The admissible storage temperature range is –25
°C
to +55°C
Special Precautions
Once installed and connected to the AC power source for the first time, the battery will start
to charge. Full charging to obtain the rated battery backup time requires at least 8 hours.
Before and after the installation, if the UPS remains de-energized for a long period, the
UPS must be energized for a period of 24 hours, at least once every 6 months (for a normal
storage temperature less than 25
°C
). This charges the battery, thus avoiding possible
irreversible damage.
During the replacement of the battery module, it is imperative to use the same type and
number of element previously mounted in the UPS, in order to maintain an identical level of
performance and safety. In case of doubt, don’t hesitate to contact our after sales
department (for more information, refer to the web site www.mgeups.com).
