Emergency Stop Circuit
For immediate shutdown and to prevent unexpected startup, an emergency stop circuit must be used.
The design of a suitable safety concept for operation of a machine with the described controller is the
responsibility of the operator.
NOTICE
Electrostatic sensitive devices (ESDs) are individual components, integrated circuits, or modules that may be dama-
ged by either electrostatic fields or electrostatic discharge.
Regulations for handling ESD components:
When handling electronic components, make sure that personnel, workstations, and pakkaging are well grounded!
Personnel may only come into contact with electronic components, if
•
they are grounded with an ESD wrist band, or
•
they are in ESD areas with conductive flooring, ESD shoes or ESD grounding straps.
Electronic modules should only be touched if absolutely necessary.
They must only be handled on the front panel or, in the case of circuit boards, at the edge.
Electronic modules must not come into contact with plastics or items of clothing containing synthetic fibres.
Electronic modules must only be placed on conductive surfaces (work surfaces with ESD surface, conductive ESD
foam, ESD packing bag, ESD transport container).
Do not place electronic modules near display units, monitors, or television sets (minimum distance from screen > 10
cm).
Measurements can only be taken on electronic modules when the measuring device is grounded (e.g. via protective
conductors) or, in the case of an isolated measuring device, when the measuring probe is briefly discharged before
measurements are taken (e.g. by touching a bare metal housing).
NOTICE
The components must be protected against conductive contamination, for example:
- Compliance with the standards (chapter 12 „Standards and approvals“ on page 149)
- Inspection of the safety equipment
- Installation in a cabinet with a degree of protection IP54B according to EN 60529
Under the circumstances that conductive contamination at the installation site can definitely be excluded, a lower
degree of cabinet protection may be permitted.
