Read the manual attentively and respect the safety instructions which are
mentioned in this chapter before doing taking further steps (transport, storage,
connection, setting-up, etc.).
As UPS-systems are working with voltage and have got corresponding internal
or external energy storages (batteries with high capacity), the instructions in this
chapter are very important for all users and the whole stuff. Therefore we also
mention safety instructions for batteries and battery packs. Nevertheless you
have to respect the own instructions of external battery packs when using them.
To ensure the safety of applications in which the UPS is going to be connected
with power supply, you have to assure that the unit is installed by a qualified
electric installation company.
The UPS disposes of an intern energy source (battery). There can be voltage
on the terminal output, if the battery should be switched-on even if there is no
AC.
Ensure that the AC output is correctly grounded.
Do not open the casing, because there are just parts which are maintenance-
free. The guarantee expires by opening the casing unauthorized.
Do not try to repair the unit by yourself. Contact your retailer or your guarantee
will expire.
Ensure that input voltage of the UPS corresponds to the supplying voltage.
Use certificated mains cords with fitting plug-ins and sockets for the
corresponding voltage supplying system.
Dusty, corrosive and saline environments can damage the UPS.
Do not install the UPS close to devices which heat excessively and in very wet
environments. Do not expose to direct sunlight.
The battery pack usually unloads itself when the system has not been used for
a longer period of time.
In case of non-use the battery pack should be loaded every 2-3 months. In
case of non-observance the guarantee expires. During the installation and
operation, the batteries reload automatically and are kept in good condition.
