Destruction of the device
Devices with a 230V mains connection must not be connected to a
three−phase 400V mains.
Possible consequences:
ƒ
The device will be destroyed
Protective measures:
ƒ
Check the voltage between the phase conductors L1 and L2. It
must not
exceed 230/240V.
The devices in the power range of 0.25kW to 2.2kW can also be connected to a three−phase
230V mains. In this case, the following conditions must be observed:
ƒ
Both mains phases L1 and L2 must be fused.
ƒ
If the drive controller is connected to the mains via a contactor or similar, both
mains phases L1 and L2 must be switched via the contactor.

Note!
The discharge current against ground is higher than when supplied via a
one−phase 230V mains. If necessary, the application of a safety switch with a
higher fault current must be observed.
