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 mains.
If a RCD is required a B-type should be used.
The short circuit current (Icw) according to UL1778 is 10kA rms.

1. Circuit breaker switch recommended with magnetic intervention threshold
≥
10 In (curve D). 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. 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.
3. Use tin plated copper lugs.
CAUTION!
To reduce the risk of fire, connect only to a circuit provided with 200 A maximum branch circuit
overcurrent protection in accordance with the National Electrical Code, ANSI/NFPA 70 and the
Canadian Electrical Code, Part I, C22.1.
The UPS is designed for transient overvoltages in category II installations. If the UPS is part of the
building’s electrical circuit, or is likely to be subject to transient overvoltages in category III installa-
tions, additional external protection must be provided, either on the UPS or in the AC power supply
network powering the UPS.
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.
