Please note the following
● It is only permissible to use a delayed tripping, selective AC/DC-sensitive residual-
current circuit-breakers, Type B.
● The max. permitted grounding resistance of the "selective protective equipment" is
included (83 Ω max. for residual-current circuit-breakers with 0.3 A rated differential
current).
● Accessible parts of the Power Drive System and the machine are connected to the
system's protective ground conductor.
● 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-breakers in
accordance with EN 61009-1 of the 5SM series (e.g. 5SM3646-4 or 5SM3646-4+5SW3300
with an auxiliary disconnector (1 NC contact/1 NO contact) for a rated current of 63 A and
rated fault current of 0.3 A (see catalog "BETA Modular Installation Devices - ET B1")).
NOTICE
AC or pulse-sensitive RCCBs are not suitable.
