WARNING
High housing voltage and high leakage current! Danger to life, risk of
injury by electric shock!
● Before switching on and before commissioning, ground or connect the
components of the electric drive and control system to the equipment
grounding conductor at the grounding points.
● Connect the equipment grounding conductor of the components of the
electric drive and control system permanently to the main power supply at
all times. The leakage current is greater than 3.5 mA.
● Establish an equipment grounding connection with a copper wire of a
cross section of at least 10 mm
2
(8 AWG) or additionally run a second
equipment grounding conductor of the same cross section as the original
equipment grounding conductor.
1.1.3 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
Dangerous movements 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 electric 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 dam‐
age, 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 move‐
ments depends upon the type of control and the state of operation.
