Connecting Equipment Grounding Conductor
WARNING
Lethal electric shock when touching the
housing caused by faulty connection of
equipment grounding conductor!
⇒ Observe the mentioned notes on installation in any
case, in order to prevent danger by electric shock
when touching the housing, even in case an
equipment grounding conductor connection is
broken.
Equipment Grounding Connection between the
Components
Observe the notes on installation in chapter, section.
Connecting Equipment Grounding Conductor to Mains
According to the standards "Electronic equipment for use in power
installations" (EN 50178, 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 following requirements have to be complied with:
• cross section of equipment grounding conductor at least 10 mm
2
(reason: sufficient mechanical stability required)
• mains and current supply automatically cut off when equipment
grounding conductor interrupted (case of error)
• Routing of a second equipment grounding conductor, via separate
terminal connectors, with the same cross section as the first
equipment grounding conductor. Mounting of an additional terminal
connector for this equipment grounding conductor.
Use of Residual-Current-Operated Circuit-Breakers (RCCB, RCD) as
Additional Fusing
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)
Note: Rexroth IndraDrive drive systems can only be used with
residual-current-operated circuit-breakers to a limited extent.
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
• for switch-on processes, due to high asymmetric inrush currents and
• during operation of the installation, due to leakage currents produced
in normal operation.
