WARNING
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!
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
2
.
The units must be fused on the mains side with semiconductor fuses as
detailed in Table 3.2. 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 3.3. Mains plus commutation activity must be
≥
3% u
k
(ac
load carrying capacity of the dc link capacitors in the inverter). See Table 3.2
for details of order numbers for fuses.
The connection cross-sections given in Table 3.1 were determined for copper
cables at 40
°
C (104 °F) ambient temperature. Data applies to multiple-wire
cables.
The terminals accept the following range of cables:
Type B: 2,5mm

to 16mm

/ AWG 14 to AWG 6
Type C: 10mm

to 50mm
