  • Page 6: Intended Use

    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.
  • Page 7 General information • Safety Danger! Risk of injury due to electric shock! If live parts are touched, there is immediate danger of fatal electric shock. If connections are connected or disconnected in the incorrect order or when the power is switched on, electric arcs can occur and persons and contacts can be damaged.
  • Page 8 General information • Safety Danger! Danger of injury due to rotating or moving elements and loads! By rotating or moving elements, body parts can be drawn in or severed or subjected to impacts. • Do not stay in the danger zone during operation and secure it against access by unauthorized persons.
