Page 7: Safety Instructions
Overview This chapter states the general safety instructions that must be followed when installing and operating the FEN-11. 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.
