Page 8: Electrical Safety Precautions
8 Safety instructions Only a qualified electrician who has appropriate knowledge on functional, machine, and process safety is allowed to install, start up and maintain the safety circuit. All user-made changes are on the user's responsibility. WARNING! This safety function does not disconnect the voltage of the main and auxiliary circuits from the drive. - Page 9 Safety instructions 9 • Disconnect any dangerous external voltages from the control circuits. • After you disconnect power from the drive, always wait 5 minutes to let the intermediate circuit capacitors discharge before you continue. 3. Protect any other energized parts in the work location against contact. 4.

Page 15: Option Description
Option description 15 Option description Contents of this chapter This chapter describes the option +Q957, prevention of unexpected start-up, and its settings. Overview The Prevention of unexpected start-up (POUS) function disables the control voltage of the power semiconductors of the drive (inverter) output stage. This prevents the drive from generating the torque required to rotate the motor. -
