Figure 3.1 Mains connection
Incorrect connection to the mains will destroy the unit!
The excitation coils of contactors and relays connected to the same mains network as the
unit, or which are located in its proximity, must be wired with surge arresters, e.g. RC
networks.
The unit must not be operated via a current-operated earth-leakage circuit-breaker (DIN
VDE 0160).
A voltage may only be applied to the unit after connecting SIMOVERT Master Drives.
Swapping or shorting the dc link terminals will destroy the SIMOVERT Master Drives
inverter!
NOTE:
Type 6SE7036-1EE85-0RA0 double rectifiers must be grounded at both straps owing to the strap current
carrying capacity.
To avoid retroactive effects on the mains and to limit harmonics, the mains should be connected via a 2 %
commutation choke as detailed in Table 3.4. Mains plus commutation activity must be ≥ 3% u
carrying capacity of the dc link capacitors in the inverter).
The units are intended for permanent connection to the mains in conformity with DIN VDE 0160 Section
6.5.2.1. PE conductor connection: minimum cross-section 10mm
The connection cross-sections indicated in Table 3.1 are the maximum cross-sections which can be
connected. The information given is for multi-core cables. The cross-sections actually wired and the
associated connecting elements are to be selected in accordance with the regulations applicable in each
case - e.g. DIN VDE 100 Part 523, DIN VDE 0276 Part 1000, UL, CSA, . . . .
