Safety and warning notices Note: Damage to the controller! Changing the wiring during operation may damage the controller. ► Only change the wiring in a de-energized state. After switching off, wait until the capacitors have discharged. Note: Damage to the controller due to excitation voltage of the motor! Voltage peaks during operation may damage the controller. ► Install suitable circuits (e.g., charging capacitor) that reduce voltage peaks. Note: Damage to the electronics through improper handling of ESD-sensitive components! The device contains components that are sensitive to electrostatic discharge. Improper handling can damage the device. ► Observe the basic principles of ESD protection when handling the device. Note: Damage to the electronics if the supply voltage is connected with reversed polarity! Polarity reversal results in a short-circuit between supply voltage and GND (earth) via the power diode. ► Install a line protection device (fuse) in the supply line.
