● The total length of the shielded power cables in the drive line-up (motor cables incl. line
supply cables from line filters to the connecting terminals of the line module) must be less
than 350 m.
● Only recommended line filters must be used during operation.
● Only one residual-current circuit-breaker may be connected in series (cascading is not
possible).
● Switching elements (main power switch, contactor) for connecting and disconnecting the
drive group have max. 35 ms delay time time between the closing/opening of the
individual main contacts.
Recommendation
SIEMENS selectively switching AC/DC-sensitive residual-current circuit-breaker in
accordance with EN 61800-5-1 of the 5SM series, e.g. 5SM36465 or 5SM36465+5SW3300
with auxiliary separation switch (1 break contact / 1 make contact) for 63 A rated current,
0.3 A rated residual current (see "BETA Installation Built-in Devices - ET B1" catalog).
Notice
AC or pulse-sensitive RCCBs are not suitable.
