Technical data

DANGER
High housing voltage and high leakage current! Risk of death or bodily
injury by electric shock!
⇒ Before switching on, the housings of all electrical equipment and motors must
be connected or grounded with the equipment grounding conductor to the
grounding points. This is also applicable before short tests.
⇒ The equipment grounding conductor of the electrical equipment and the de-
vices must be non-detachably and permanently connected to the power supply
unit at all times. The leakage current is greater than 3.5 mA.
⇒ Over the total length, use copper wire of a cross section of a minimum of
10 mm
2
for this equipment grounding connection!
⇒ Before commissioning, also in trial runs, always attach the equipment ground-
ing conductor or connect to the ground wire. Otherwise, high voltages may
occur at the housing causing electric shock.
3.5 Protection Against Electric Shock by Protective Extra-Low
Voltage
All connections and terminal connectors with a voltage of 5 to 50 Volt on Rexroth
Indramat products are protective extra-low voltages, which are performed safe
from touch according to the product standards
WARNING
High electric voltage by incorrect connection! Risk of death or bodily
injury by electric shock!
⇒ Connect only devices with connectors and terminal connectors with a voltage
of 0 to 50 volt, which have a protective extra-low voltage (PELV).
⇒ Connect only voltages and circuits, which have a safe disconnection to dan-
gerous voltages. A safe disconnection can be done, for example, by isolating
transformers, safe optocouplers or operation from battery.
3.6 Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of connected motors.
Some common examples are:
● improper or wrong wiring of cable connections
● incorrect operation of the equipment components
● wrong input of parameters before operation
● malfunction of sensors, encoders and monitoring devices
● defective components
● software or firmware errors
These errors can occur immediately after equipment is switched on or even
after an unspecified time of trouble-free operation.
The monitoring in the drive components will normally be sufficient to avoid faulty
operation in the connected drives. Regarding personal safety, especially the
danger of bodily harm and/or material damage, this alone cannot be relied upon
to ensure complete safety. Until the integrated monitoring functions become
effective, it must be assumed in any case that faulty drive movements will occur.
The extent of faulty drive movements depends upon the type of control and the
state of operation.
