2. Safety notices
2.1 Intended use
Programmable logic controllers (PLCs), operating and monitoring devices (industrial PCs, Power
Panels, Mobile Panels, etc.), and B&R uninterruptible power supplies have been designed,
developed, and manufactured for conventional use in industry. They were not designed,
developed, and manufactured for any use involving serious risks or hazards that could lead to
death, injury, serious physical damage, or loss of any kind without the implementation of
exceptionally stringent safety precautions. In particular, such risks and hazards include the use
of these devices to monitor nuclear reactions in nuclear power plants, as well as flight control
systems, flight safety, the control of mass transit systems, medical life support systems, and the
control of weapons systems.
2.2 Protection against electrostatic discharges
Electrical components that are vulnerable to electrostatic discharge (ESD) must be handled
accordingly.
2.2.1 Packaging
• Electrical components with housing
… do not require special ESD packaging, but must be handled properly
(see "Electrical components with housing").
• Electrical components without housing
… must be protected by ESD-suitable packaging.
2.2.2 Guidelines for proper ESD handling
Electrical components with housing
• Do not touch the contacts of connectors on connected cables.
• Do not touch the contact tips on the circuit boards.
Electrical components without housing
In addition to "Electrical components with housing", the following also applies:
• Any persons handling electrical components or devices that will be installed in the
electrical components must be grounded.
• Components can only be touched on the small sides or on the front plate.
• Components should always be stored in a suitable medium (ESD packaging, conductive
foam, etc.).
Metallic surfaces are not suitable storage surfaces!
