2.4 Protection Against Electric Shock by Protective Low
Voltage (PELV)
All connections and terminals with voltages between 5 and 50 Volt at
Rexroth products are protective extra-low voltage systems which are
provided with touch guard according to the product standards.
WARNING
High electric voltage by incorrect connection!
Risk of death or bodily injury by electric shock!
⇒
To all connections and terminals with voltages
between 0 and 50 Volt, only devices, electrical
components, and conductors may be connected
which are equipped with a PELV (Protective Extra-
Low Voltage) system.
⇒
Connect only voltages and circuits which are safely
isolated from dangerous voltages. Safe isolation is
achieved for example by isolating transformers, safe
optocouplers or battery operation without mains
connection.
2.5 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
Dangerous movements 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 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.
