UNPACKING AND INSTALLATION
OF THE UNIT
3.4 ELECTRICAL REQUISITES.
The installation and the system must comply with national plant regulations. The electrical distribution panel must
have a protection and sectioning system installed for the input mains and the auxiliary mains. If a di erential switch
is installed on the mains power switch (optional), it must be inserted upstream from the distribution panel.
The table below show the size of the input protection devices recommended for correct installation.

Caution! Use type B selective circuit breakers. Load leakage currents are added to those generated by the UPS and during transitory phases
(power failure and power return) short current peaks may occur. If loads with high leakage current are present, adjust the di erential protection.
It is advisable in all cases to carry out a preliminary check on the earth current leakage with the UPS installed and operational with the de nitive
load, so as to prevent the sudden activation of the above switches.
This unit has been designed for connection to an ordinary AC power supply, i.e. with transient voltage
in overvoltage II category. Should it be necessary to connect the UPS to a higher overvoltage category
(e.g. at the beginning of the installation, or to primary distribution circuits), or should the UPS risk
being exposed to higher transient overvoltages, adequate external protections must be installed.
