Connections and cables
The following block diagrams and tables describe the details and limitations of the
connections on the converter.
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.
The maximum cable lengths for all the converters are shown in the following table.
Table 4- 4 Maximum cable lengths
Digital outputs Unscreened 15 m (49 ft)
Motor cable with Wall Mount Kit
The maximum cable lengths for communications 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:
