The cable layout of the external consumers must conform to the associated conditions:
● The loading by the attached consumers (also refer to the Equipment Manual for Booksize
Power Units); the concurrency factor depending on the operation of the machine may
need to be considered.
● Current carrying capacity of the conductors used and cables in normal and short-circuit
conditions
● The ambient temperature
● The bunching of the cables, e.g. laying in a single duct
● the cable types
The EN60204-1 and VDE 660 Part 500 can be used to determine the over-current protective
devices.
If required, the circuit-breakers can be equipped with additional auxiliary switches. If these
signal contacts are fed to a higher-level controller, a detailed fault diagnosis can be
performed when the circuit-breakers trip.
5.7.3 Interconnection of the voltage output for the CSM
Interconnection of the 24 VDC voltage output for the Control Supply Module
● Exclusive supply of the drive group
The appropriate jumper plugs are used to connect the secondary 24 VDC voltage output
to the 24 V busbar of the drive group. The Control Supply Module so supplies only the
drive group consisting, for example, of Line, Motor, Capacitor and Braking Module.
An additional SITOP Modular power supply must be provided to supply power to the
other external consumers.
● Supply of external components, such as CU and SMC
An appropriate connection adapter can be used to also supply power for external
consumers. For example, only a specific Control Supply Module can be used for these
consumers. This means an external power supply can be omitted.
Notice
The maximum current carrying capacity of the DC link busbars is 100 A. This must be
considered for the positioning of the CSM in the drive group. The CSM must not be
installed between or in front of the 300 mm components! In preference, the CSM should
be placed at the end of the drive group.
