3.5 ELECTRICAL REQUIREMENTS.
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.
WARNING!
The default transformer is normally connected to the output.

1
Recommended magneto thermal switch: four poles with intervention threshold ≥ 10 In
2
In systems with two or more UPSs operating in a redundant or power parallel con guration.
3
Determined by the size of the terminals.
4
Protection on the external battery cabinet.
5
Caution! Use type B four-pole selective (S) 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.
