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.
The table below show the size of the input protection devices recommended for correct installation.

1. Recommended magneto thermal switch: four poles with intervention threshold ≥ 10 In
2. Caution! Use type B four-pole selective (S) type differentials. load leakage currents are added to those generated by the UPS and during transi-
tory phases (power failure and power return) short current peaks may occur. If loads with high leakage current are present, adjust the differential
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
definitive load, so as to prevent the sudden activation of the above switches.
3. Minimum section acceptable for the UPS's sockets. Use the same section also for rigid cables.
4. Maximum section acceptable for the UPS's sockets is 95 mm
The UPS is designed for transitory overvoltages in category II installations. If the UPS is part of the building's
electric circuit or if it is likely to be subject to transitory overvoltages in category III installations, further exter-
nal protection must be provided, either on the UPS or in the AC power supply network to the UPS.
In the event of three-phase distorting loads connected in output, the current on the neutral conductor may have
a value that is 1.5 - 2 times the phase value (also for the input bypass). In this case, size the neutral cables and the
input/output protection adequately.
