4.8.4 Mains fuse
In the mains power supply cable, an automatic circuit breaker is installed for protection of the line:
Motor controller
Phases Mains fuse
1)
CMMP-AS-C2-3A-M0 1 B10
CMMP-AS-C5-3A-M0 1 B16
CMMP-AS-C5-11A-P3-M0 3 B16
CMMP-AS-C10-11A-P3-M0 3 B16
1) The required fuse is dependent, among other things, on the cable cross section, ambient temperature and laying procedure.
Observe the following instructions!
Tab. 4.19 Required mains fuses
In designing the fuses, also observe the following standards:
EN 60204-1 “Safety of machinery – Electrical equipment of machines – Part 1:
General requirements”
Take into consideration the legal regulations applicable for the destination as well as:
– Regulations and standards,
– Regulations of the testing organisations and insurers,
– national specifications.
4.8.5 AC supply
Switch-on behaviour:
– As soon as the motor controller CMMP-AS-...-M0 is provided with mains voltage, the intermediate
circuit is charged ( 1 s) via the braking resistors, with the intermediate circuit relay deactivated.
– After the intermediate circuit has been pre-charged, the relay engages and the intermediate circuit
without resistors is connected directly to the mains supply.
AC supply with active PFC
The PFC step is available only for 1-phase motor controllers (CMMP-AS-...-3A-M0).
Note
Operation with mains line choke is not permissible, since the control circuit could be
stimulated to oscillate.
Note
Operation with isolating transformer is not permissible as no reference potential (N) is
available.
