1 L EDB9300EN-V004 EN 4.0 1 Preface and general information 1.1 Principle of operation The V004 variant of the 9300 range of controllers supports the ”Safe standstill” safety function and protects against unexpected start-up according to the requirements of EN 954-1 “Control category 3” and EN 1037. The controllers are therefore equipped with an integrated safety relay with feedback contact. The safety relay isolates ...

1.3 Safety and application notes for Lenze controllers (in conformity with Low-Voltage Directive 73/23/EEC) General Lenze controllers (frequency inverters, servo inverters, DC controllers) can include live and rotating parts - depending on their type of protection - during operation. Surfaces can be hot. Non-authorized removal of the required cover, inappropriate use, incorrect installation or operation, creates ...

Electrical connection When working on live drive controllers, the applicable national regulations for the prevention of accidents (e.g. VBG 4) must be observed. The electrical installation must be carried out according to the appropriate regulations (e.g. cable cross-sections, fuses, PE connection). Additional information can be obtained from the documentation. The documentation contains information about instal ...

1.4 Additional safety notes for the “Safe standstill” function • Only qualified personnel are permitted to install and set up the “Safe standstill” function. • All safety-relevant external cables (e.g. control cable for the safety relay, feedback contact) must be protected, for instance by a cable duct. Short circuits between signal and ground and between signal cables must be avoided. • In the eve ...
