Introduction
CAUTION: Safety of persons
◗ 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 3.5 mA by checking their characteristics (maximum leakage current of the UPS = 2 mA).
◗ 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 handling: remove watches, rings, bracelets and any other metal objects, use tools with insulated handles.
- Do not lay tools or metal parts on top of batteries.
CAUTION: 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 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 -25ºC to +55ºC.
Special precautions
◗ All handling operations will require at least two people (unpacking, installation in rack system).
◗ 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).
