  • Page 7: Safety Instructions

    Overview This chapter states the general safety instructions that must be followed when installing and operating the FEN-01. In addition to the safety instructions given below, read the complete safety instructions of the specific drive you are working on.
  • Page 8 8 Safety instructions The motor cable terminals of the drive are at a dangerously high voltage when mains power is applied, regardless of motor operation. There can be dangerous voltages inside the drive from external control circuits even when the drive mains power is shut off. Exercise appropriate care when working on the unit.

  • Page 9: Introduction

    Intended audience The manual is intended for the people who are responsible for commissioning and using the FEN-01. The reader is expected to have a basic knowledge of electrical fundamentals, electrical wiring practices and how to operate the drive. Before you start It is assumed that the drive is installed and the drive power supply is switched off before starting the installation of the extension module.
