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 diff 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.
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 external protection must be provided, either on the UPS or in the AC power
supply network to the UPS. In addition, the “Surge arrestor” option, specially designed to protect
against residual overvoltages in category III installations, can be installed in the external manual
bypass cabinet. If used, the distance between the UPS and the centralised 4 kV SPD protections
type 1 must be Up ≤ 4kV is ≥ 15m.
In the event of three-phase distorting loads connected in output, the current on the neutral con-
ductor 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.

Recommended magneto thermal switch: four poles with intervention threshold ≥ 10 In

In installations with two UPSs operating in a redundant or power parallel confi guration.
3
Quadrupole protection on external battery cabinet.

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 diff 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
defi nitive load, so as to prevent the sudden activation of the above switches.

Determined by the size of the terminals.

Recommended magneto thermal switch: four poles with intervention threshold ≥ 3 In
