Chapter 2 • Intended use
These products are developed and produced exclusively for training and development in the area of automation.
Any use beyond this is not permitted, in particular the integration of these products or parts thereof in machines,
systems or other devices and processes. B&R does not assume liability for damages of any kind that occur when
using the products outside of training and development or for harm that results from modifying the products. Ex-
pansions using products from the ETA system or ETA light system series are permitted.
In addition, the products are only permitted to be used in closed rooms (such as laboratories, offices and class-
rooms) that do not require separate protective equipment. Trainers shall inform the trainees of the relevant safety
guidelines and precautions before using the product.
1 Protection against electrostatic discharge
Electrical assemblies that can be damaged by electrostatic discharge (ESD) must be handled accordingly.
1.1 Packaging
•
Electrical assemblies with housing:
Do not require special ESD packaging but must be handled properly (see "Electrical assemblies with hous-
ing").
•
Electrical assemblies without housing:
Are protected by ESD-suitable packaging.
1.2 Regulations for proper ESD handling
Electrical assemblies with housing
•
Do not touch the connector contacts of connected cables.
•
Do not touch the contact tips on circuit boards.
Electrical assemblies without housing
The following applies in addition to "Electrical assemblies with housing":
•
All persons handling electrical assemblies and devices in which electrical assemblies are installed must
be grounded.
•
Assemblies are only permitted to be touched on the narrow sides or front plate.
•
Always place assemblies on suitable surfaces (ESD packaging, conductive foam, etc.). Metallic surfaces
are not suitable surfaces!
•
Assemblies must not be subjected to electrostatic discharges (e.g. due to charged plastics).
•
A minimum distance of 10 cm from monitors or television sets must be maintained.
•
Measuring instruments and devices must be grounded.
•
Test probes of floating potential measuring instruments must be discharged briefly on suitable grounded
surfaces before measurement.
Individual components
•
ESD protective measures for individual components are implemented throughout B&R (conductive floors,
shoes, wrist straps, etc.).
•
The increased ESD protective measures for individual components are not required for handling B&R
products at customer locations.
2 Regulations and measures
Electronic devices are generally not failsafe. If the programmable logic controller, operating or control device or
uninterruptible power supply fails, the user is responsible for ensuring that connected devices (such as motors)
are brought to a safe state.
