1. Safety Guidelines

1.1 Introduction

Programmable logic controllers (e.g. PLCs, etc.), operating and monitoring devices (e.g.
Industrial PCs, Power Panels, Mobile Panels, etc.) as well as the 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 without the implementation of exceptionally stringent safety precautions could lead
to death, injury, serious physical damage or loss of any other kind. Such risks and hazards
include in particular the use of these devices in the monitoring of nuclear reactions in nuclear
power plants and of flight control systems, in flight safety, in the control of mass transportation
systems, in medical life support systems, and in the control of weapons systems.
Both when using programmable logic controllers and when using operating and monitoring
devices as control systems in conjunction with a Soft PLC (e.g. B&R Automation Runtime or
comparable products) or a Slot PLC (e.g. B&R LS251 or comparable products), the safety
precautions applying to industrial control systems (e.g. the provision of safety devices such as
emergency stop circuits, etc.) in accordance with applicable national and international
regulations must be observed. The same applies for all other devices connected to the system,
such as drives.
All tasks such as installation, commissioning and service may only be carried out by qualified
personnel. Qualified personnel are persons who are familiar with transport, mounting,
installation, commissioning and operation of the product and have the appropriate qualifications
(e.g. IEC 60364). National accident prevention guidelines must be followed. The safety
guidelines, connection descriptions (rating plate and documentation) and limit values listed in the
technical data must be read carefully before installation and commissioning and must be
observed.

1.2 Intended Use

Electronic devices are generally not fail-safe. In the event of a failure on the programmable
control system, operating or monitoring device or uninterruptible power supply, the user is
responsible for ensuring that other devices that may be connected, such as motors, are made
safe

1.3 Transport and Storage

During transport and storage, the devices must be protected from excessive stress (mechanical
load, temperature, humidity, aggressive atmosphere).
