cross section being too small!
NOTICE
Observe the current carrying capacity of the connection points for control
voltage supply at the components used.
You may only loop through the control voltage between the components,
when the sum of current consumptions ΣI
N3
of the individual components is
smaller than 10 A (current carrying capacity of the connection point X13).

has to be smaller than the specified current carrying capacity of
the connection point.

Residual-current-operated circuit breakers (RCD, RCCB) as additional fusing
General information
The following designations are used for residual-current-operated circuit
breakers:
●
RCCB (Residual-Current-Operated Circuit Breaker)
●
RCD (Residual-Current-Operated Device)
●
RCM (Residual-Current Monitoring Device)
●
Earth-leakage circuit breaker (voltage-independent)
●
Residual-current circuit breaker (voltage-dependent)
It is only to a limited extent that residual-current-operated circuit
breakers can be used with Rexroth IndraDrive Cs systems.
If these circuit breakers are to be used, the company erecting the installation
has to check the mutual compatibility of the residual-current-operated circuit
breakers and installation or machine with the drive system, in order to avoid
accidental triggering of the residual-current-operated circuit breaker. This has
to be taken into account
