Connection and cables

Connections and cables
The following block diagrams and tables describe the details and limitations of the
connections on the converter.
Wiring stripping
The following components are delivered with pre-prepared cables and no wire stripping is
necessary:
● Internal 24 V DC power supply
● Internal braking resistor for FSA
● Internal braking resistor for FSB
● Motor EM brake
● The motor terminals for the terminal housing (for connection to the motor terminals).
All other connections to the Phoenix mains and motor connectors need to be stripped to a
length of 10 mm, with a maximum torque of 0.8 Nm.
Cable lengths
The maximum cable lengths for all the converters are shown in the following table.

The maximum cable lengths for USS, PROFIBUS and PROFINET are determined by a
number of factors, for example, the maximum length of the cable for USS and PROFIBUS
are dependent on the data transfer rate being utilized by the network.
In some cases, it is possible to extend the cable length by the use of appropriate repeaters.
The maximum cable lengths for the various communications protocols are given in the
following table:
