MASTERYS GP4 60-160 kVA - Ref.: IOMMASGPXX07-EN 05
NOTE:
To ensure the integrity of the 60-80 kVA bypass thyristors, I
2
t must be lower than 120 kA
2
s and
peak current must be lower than 5 kA for 20 ms.
To ensure the integrity of the 100-160 kVA bypass thyristors, I
2
t must be lower than 400 kA
2
s 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 electrical 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.
The UPS is designed for indoor environmental service conditions according to IEC 60721-3-3
with pollution degree lower or equal to 2 (non-conductive pollution).
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-C, TN-S, TT and IT AC distribution systems (IEC 60364-3).
