As delivered, the device is configured for operation in TN or TT networks. For operation in IT
networks, simple adaptations must be made. However, these impair the suppression of radio
interference.
Adaptation is carried out via two screw connections. The two screws must be removed from the
housing to enable IT network operation.
1) Motor output 2) Mains input
Adaptation to HRG networks
The device may also be operated in supply networks with a high resistance earthed star point ( H igh
R esistance G rounding) (typical for the US American region). For this, the same conditions and
modifications must be taken into account as for operation in an IT network (see above).
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 (Chap. 2.5.3.2 "Mains connection (PE, L1, L2/N, L3)")). Operation in differing
network types may be possible, but must be
explicitly checked and approved by the manufacturer
in advance .
2.5.3.3 Motor cable
The motor cable may have a total length of 100 m if it is a standard cable type (observe EMC). If a
shielded motor cable is used or if the cable is installed in a metallic and well grounded duct, the total
length should not exceed
30 m (connect cable shield to PE at both ends).
For longer cable lengths an additional motor choke (accessory) must be used.
Information
Multiple motor operation
Multiple motor operation is the parallel operation of several motors by a frequency inverter.
For multiple motor operation the frequency inverter must be changed to a linear voltage/frequency
characteristic curve (

P211 = 0 and P212 = 0 ).
For multiple motor operation the total motor cable length consists of the sum of the individual motor
cable lengths.
