3. ELECTRICAL INSTALLATION
NOTE!
Before carrying out any operations on the unit read the Safety standards chapter carefully.
3.1. ELECTRICAL
REQUIREMENTS
The installation and system must comply with national plant regulations.
The electrical distribution panel must have a sectioning and protection system installed for input and auxiliary mains.
RCD is not necessary when the UPS is installed in a TN-S system.
RCD is not allowed on TN-C systems.
If a RCD is required a B-type should be used.

1. Circuit breaker switch recommended with magnetic intervention threshold ≥10 In (curve C). It is necessary to use a D curve selective breaker
if an optional external transformer is used. The min value depends on the size of the power cables in the installation, while the max value is
limited by the UPS cabinet.
2. Determined by the size of the terminals.
3. Caution! Use type B four-pole selective (S) residual current detectors. Load leakage currents are to be added to those generated by the UPS
and during transitory phases (power failures and power returns) short current peaks may occur. If loads with high leakage current are present,
adjust the residual current 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 RCD tipping over.
4. The conditional short circuit current (Icc) according to IEC 62040-1 is 50KA rms, provided that the UPS is protected by a MCCB with adequate
breaking capability and current limiting capability under short circuit conditions. Contact SOCOMEC for detailed information.
NOTE!
To ensure the integrity of the bypass thyristors I2t must be lower than 400 kA2s and peak current must be lower
than 9 kA for 20 ms. Contact SOCOMEC for detailed information.
The UPS is designed for transient overvoltages in category II installations. If the UPS is part of the building’s elec-
trical circuit, or is likely to be subject to transient overvoltages in category III installations, additional external
protection must be provided, either on the UPS or in the AC power supply network powering the UPS.
WARNING!
As specified in 62040-3 Appendix 3: Non-linear Load Reference, in the event of three-phase non-linear loads
connected downstream of the UPS, the neutral current on the load can be 1.5 - 2 times higher than the phase
current. This must be considered when estimating the correct size of the output and the auxiliary neutral cables.
WARNING!
Protective earthing conductor (PE) must have sufficient current-carrying capacity. The PE cable core size must be
chosen according to the PROTECTIVE CURRENT RATING of the earth circuit which depends on the provision and
location of protective overcurrent devices.
NOTE!
3-Phase 4 –Wire Input Power is required. The unit can be installed in TN, TT and IT AC distribution systems (IEC 60364-3).
