Every explosion protected motor is identified uniquely with its article code (AC) and serial number (SN) (also see chapter 3.2 "Identification plate").
About this manual MRS/MMSE/ARS/TPM Safety symbols The following safety symbols are used to indicate possible hazards, prohibitions, and important information: General danger Hot surface Suspended loads Entanglement Electrostatic sensitive Information Explosion Electric voltage device Crushing hazard Pacemaker ban Design of the safety instructions The safety instructions of these instructions are designed according to the following pattern: A = Safety symbol (see Chapter 1.2 "Safety symbols") B = Signal word (see Chapter 1.1 "Signal words")
MRS/MMSE/ARS/TPM Safety Safety This instruction, in particular the safety notes, and the rules and regulations applicable at the usage site are to be observed by all individuals working with the motor. In addition to the safety instructions in this manual, also observe any (legal and otherwise) applicable environmental and accident prevention rules and regulations (e.g.
- Operation of the motor with defective protection devices and mechanisms - Operation of a severely soiled motor - Changes or modifications that have been realized without the written approval of WITTENSTEIN cyber motor GmbH Other applicable documents You have already received the following documents for your specific motor: - Customer drawing (5007–...)
