Protection of Safety-Separated Extra Low Voltages
The connections and interfaces for signal voltages from 5 to 50 V are
safety separated electrical circuits that have shock-hazard protection.
WARNING
High electrical voltage due to wrong connections
Risk of death or serious bodily injury.
⇒
Construction and design according to the following
standards:
•
Only equipment, electrical components or cabling that
is sufficiently safety-separated from the connected
power circuits in accordance with IEC 364-4-41, 413.5
or DIN EN 50178, 12.94, section 5.2.18 may be
connected to the signal voltage connectors and
interfaces of this equipment.
Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of the motors or
other moving elements that are connected to this control.
DANGER
Malfunction in the control of motors and moving
elements
Equipment damage can occur.
⇒
Construction and design according to the following
standards:
The causes can be as follows:
•
software errors
•
defects in parts of the components
•
wiring or cabling errors
•
malfunction of measuring and signaling encoders
•
inappropriate or incorrect operation of equipment
Dangerous movements can occur immediately after
equipment is switched on or even after an unspecified
period of trouble-free operation. The monitoring systems
in this control make malfunctions in the connected drives
very unlikely. For protection of personnel, however, one
cannot depend solely on this functionality. Until the built-
in monitoring systems become active and effective, it
must always be assumed, in any case, that some faulty
drive movements will occur. The extent of these faulty
drive movements depends upon the type of fault and the
operating state.
For the above reasons, personnel safety must be
ensured by means of monitoring or measures
implemented at the facility in which the drives are used.
These monitoring systems or measures are planned by
the machine builder in accordance with the specific
conditions of the facility, following a risk and fault
analysis. All the valid safety regulations that apply to the
machine are taken into consideration.
