Suitable cable types
The table below shows the suitable cable types and their applications. You can find
a list of cables and their order numbers in Appendix
A. If cables other those listed in Appendix A are used for connecting and looping
through PROFIBUS-DP, these cables must meet the specification for cable type A
as per PROFIBUS-DP.
Table 4-2 Cable types
Cable type Application
5-core cable,
shielded
Connecting and looping through PROFIBUS-DP and supply
voltage to electronics/sensors via a common cable
3-core
copper cable, flexible
Connecting supply voltage to electronics/sensors or load
voltage
1
2-core cable,
shielded (bus cable)
Connecting and looping through PROFIBUS-DP
DESINA hybrid cable
(fiber-optic cable or
RS 485, prepared
with a DESINA
connector)
Connecting and looping through PROFIBUS-DP and
non-switched and switched supply voltages via a common
cable
The DESINA hybrid cable is supplied ready for use (wired)
with DESINA connectors in various lengths. See Appendix
A.
3-, 4- or 5-core
copper cable, flexible
Connecting the actuators and sensors to the digital
inputs/outputs
2
4-core copper cable,
shielded
Connecting the actuators and sensors to the
analog inputs/outputs
2
4 or 6-core copper
cable, flexible
Connecting the motor starter
3
:
The load and brake supply voltage (with looping through)
A load
(with brake, only a 6-core cable can be used; see the
EM 300 Motor Starters manual for order number)
4-, or 8-core copper
cable, flexible,
shielded
Connecting the frequency converter
4
:
The load supply voltage
(with looping through)
A load with brake and thermistor (only an 8-core cable)
For order number see EM 148-FC frequency converter
