2.6.3 Protective extra-low voltage
for protection against electric
shock
All connections and terminals with voltages
of 5 to 50 V on Rexroth products are pro-
tective extra-low voltages which are de-
signed to be safe to touch in accordance
with the product standards.
WARNING
High voltage due to improper
connection!
Danger to life, risk of injury due to elec-
tric shock!

Only devices, electrical components,
and cables with protective extra-low
voltage (PELV) may be connected to
connections and terminals with volt-
ages of 0 to 50 V.

Only connect voltages and electric
circuits that are safely isolated from
dangerous voltages. Safe isolation is
obtained by means of isolating trans-
formers, safe opto-couplers, or bat-
tery operation disconnected from the
mains.

2.6.4 Protection against dangerous
movements
Dangerous movements can be caused by
improper actuation of connected motors.
Causes can be any of the following:
• Careless or improper wiring
• Errors while operating the components
• Incorrect input of parameters prior to
commissioning
• Error in the measurement transducer or
signal transducer
• Defective components
• Software errors
These errors can occur immediately after
the system has been switched on or after an
indefinite operating time.
The monitoring devices in the drive compo-
nents almost completely eliminate malfunc-
tions in the connected drives. However, in
view of personal safety, especially that in-
volving risk of injury and/or damage to
equipment, this alone is not sufficient. Until
the installed monitoring devices reach full
effectivity, faulty drive movements, whose
magnitude depends on the controller type
and the operating condition, must be antic-
ipated.
