Protection Against Contact with Electrical Parts
Relevant for controls and control components with voltages above 50 V:
Making contact with parts conducting voltages above 50 V can be
dangerous to personnel. When operating electrical equipment, it is
unavoidable that some parts of the unit conduct dangerous voltages.
DANGER
Live parts (voltages higher than 50 V) on the power
supply and power section
Electric shock by touching. Risk of death or serious bodily
injury.
⇒
Construction and design according to the following
standards:
•
Follow general construction and safety regulations
when working on electrical installations.
•
After the installation, the ground wire must be
permanently connected to all electrical units according
to the connection diagram.
•
Do not operate electrical equipment at any time if the
ground wire is not permanently connected, even for
brief measurements or tests.
•
Before working with electrical parts with voltage
potentials higher than 50 V, the equipment must be
disconnected from the mains voltage or power supply.
Make sure the equipment is not switched back on.
•
Never touch the electrical connection points of a
component while power is turned on.
•
Before turning on the equipment, shield live parts to
prevent contact.
•
A residual-current-operated protective device must
not be used on an AC drive! Indirect contact must be
prevented by other means, for example, by an
overcurrent protective device (in accordance with EN
501787/ 1994, section 5.3.2.3).
•
Equipment that is built into machines must be secured
against direct contact. Use appropriate housings such
as a control cabinet, for example (in accordance with
EN 501787/ 1994).
