MGE UPS Systems EX 7RT - Manual (Page 3)

Installation and User Manual
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.
◗ The UPS must be properly grounded.
◗ 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.
Product Safety
◗ A protection circuit breaker must be installed upstream and be easily accessible..
◗ The UPS can be disconnected from the AC power source by opening the input circuit breaker.
◗ UPS must be connected to a nearby power source that is easily accessible.
◗ Never block the ventilation grates of the UPS.
◗ The UPS must be installed in a controlled environment.
Special Precautions
◗ The UPS connection instructions and operation described in the manual must be followed in the indicated order.
◗ Check that the indications on the rating plate correspond to your AC powered system and to the actual electrical consumption of all the equipment
to be connected to the UPS.
◗ 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.
