Connection for the Equipment Grounding Conductor
General Information
Lethal electric shock when touching the hous‐
ing caused by faulty connection of equipment
grounding conductor!
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.
Equipment Grounding Connection Between the Components
Observe the notes on installation.

Connecting Equipment Grounding Conductor to Mains
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.

Residual-Current-Operated Circuit Breakers (RCD, RCCB) as Addi‐
tional 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 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
