with basic insulation (such as programming devices, PCs, notebooks, display
units) to these connections.
WARNING
Danger to life, risk of injury by electric shock! High electrical voltage by
incorrect connection!
If extra-low voltage circuits of devices containing voltages and circuits of more
than 50 volts (e.g., the mains connection) are connected to Bosch Rexroth
products, the connected extra-low voltage circuits must comply with the re‐
quirements for PELV ("Protective Extra-Low Voltage").
3.3.3
Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of connected motors.
Some common examples are:
●
Improper or wrong wiring or cable connection
●
Operator errors
●
Wrong input of parameters before commissioning
●
Malfunction of sensors and encoders
●
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 functions in the components of the drive and control system will
normally be sufficient to avoid malfunction in the connected drives. Regarding
personal safety, especially the danger of injury and/or property 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 de‐
pends upon the type of control and the state of operation.
