conditions stated in Section 8.1.3 "EMC of device". In this case, additional interference suppression
measures must be provided.
Size 2 devices can in principle be operated in TN/TT networks. The device must be appropriately
configured for operation in an IT network. This configuration can also be carried out at a later date;
however it can only be carried out by the manufacturer. With the operation a device which is
configured for an IT network, compliance with the EMC limit value class B cannot be ensured under
the conditions stated in Section 8.1.3 "EMC of device". In this case, additional interference
suppression measures must be provided.
Use with differing supply networks or network types
The frequency inverter may only be connect to and operated in supply networks which are explicitly
stated in this section (

Section 2.3.2.1 "Mains supply (L1, L2, L3, PE)")). Operation in deviating
network types
may be possible, but must be
explicitly checked and approved by the
manufacturer in advance .
2.3.2.2 Motor cable (U, V, W, PE)
The motor cable must be connected properly.
2.3.2.3 Electromechanical brake
The device generates an output voltage at terminals 79 / 80 (MB+ / MB-) for actuating an
electromagnetic brake. This is dependent on the supply voltage that is present in the device. The
allocation is as follows:
Mains voltage / AC voltage Brake coil voltage (DC)
230 V ~ 105 V =
400 V ~ 180 V =
460 V ~ / 480 V ~ 205 V =
500 V ~ 225 V =
The assignment of the correct brake and brake coil voltage must be taken into consideration in the
design with regard to the mains voltage of the device.
Information
Parameters P107 / P114
For the connection of an electro-mechanical brake to the terminals of the device, parameters P107 / P114 (brake
application time / release time ) must be adjusted. In order to prevent damage to the brake control, parameter
(P107) must contain a non-zero value.
