General information • Safety Chapter 1 • General information 1 Manual history Version Date Notes 1.00 2019-06-11 First edition Information: B&R makes every effort to keep user's manuals as current as possible. New versions are available in electronic form on the B&R website (www.br-automation.com). Check regularly to determine if you have the latest version.
General information • Safety 3.2 Intended use B&R motors and gear motors are components designed for installation in electrical systems or machines. They were designed, developed and manufactured for general industrial use. They are intended to be operated in covered rooms and under normal climatic conditions, which is usually the case in modern production halls.
