GB SAFETY GB
This part of the manual contains precautions that must be adhered to strictly since they
regard SAFETY.
a) THE UPS MUST NOT OPERATE WITHOUT AN EARTH CONNECTION. The first connection to
be carried out is the earth conductor, which has to be connected to the terminal marked .
b) Avoid connecting the output neutral to the input neutral or to earth as this could cause malfunctions.
c) DANGEROUS electrical voltages are generated inside the UPS. All installation and maintenance
operations must be carried out EXCLUSIVELY by authorized personnel.
d) The UPS contains an internal power source: the batteries. The terminals and the output sockets may be
powered even when the UPS is not connected to the mains.
e) The total battery voltage can generate an electric shock. Replaced batteries should be considered as
TOXIC WASTE and treated as such. Do not throw the battery packs into fire: they may explode. Do
not try to open the battery packs: they do not require any maintenance. Furthermore the electrolyte is
dangerous if it comes into contact with the skin or the eyes and may be toxic.
f) Do not switch the UPS on if there is any leak of liquid, or if a residual white powder is noted.
g) Do not allow water, liquids in general and/or other foreign bodies to get into the UPS.
h) In the event of dangerous conditions switch the UPS off with the switch located on the front panel and
open the magneto-thermal protection installed upstream of the UPS. Isolate the battery by removing the
lower part of the front panel and disconnecting the two battery pack connectors.
i) The UPS generates a leakage current of less than 2 mA.
Warning: the leakage current of the load is added to that of the UPS on the earth protection conductor.
j) For battery expansion use exclusively connectors supplied by or authorized by the manufacturers.
k) The UPSs of this series have been designed for professional use and are therefore not suitable for use in
a domestic environment.
