General Information
WARNING
Observe the mentioned notes on installation in any case, in order to exclude
danger by electric shock when touching the housing, even in case an equip‐
ment grounding conductor connection is broken.
Observe the notes on installation.
Siehe chapter 13.1.4 "Connection Point of Equipment Grounding Conductor
and Equipment Grounding Connections" on page
According to the standards "Electronic equipment for use in power installa‐
tions" (EN50178, chapter 5.3.2.1) and "Adjustable speed electrical power
drive systems" (EN 61800-5-1, chapter 4.2.5.4.2), a stationary connection of
the equipment grounding conductor is required and one or more of the follow‐
ing requirements have to be complied with:
● Cross section of equipment grounding conductor at least 10 mm (rea‐
son: sufficient mechanical stability required)
● Mains and current supply automatically cut off when equipment ground‐
ing conductor interrupted (case of error)
● Routing of a second equipment grounding conductor, via separate ter‐
minal connectors, with the same cross section as the first equipment
grounding conductor. Mounting of an additional terminal connector for
this equipment grounding conductor.
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 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
