For other line supply types, a trans-former with separate windings in vector group yn on the secondary side must beconnected upstream (refer to Chapter 7 for the dimensioning).Table 6-8 Supply voltage and frequencyNE-Module S1.1, S1.4 = OFFUn = 3AC 400 VS1.1 = ONUn = 3AC 415 VS1.4 = ONUn = 3AC 480 VLine voltage: U1, V1, W1 3AC 400 V 10% 3AC 415 V 10% 3AC 480 V + 6% –10%With derating Prated and Pmax1) 3AC 380 V 15%DC link voltage DC 600 V DC 625 V DC 580...710 VFrequency 45...65 Hz 55...65 Hz1) See Table 6-9, Technical data I/R modulesThis means that the operational reliability is increased even when connected to weak line supplies!Supply voltageand frequency6 Infeed Modules 02.12
