MR006E Frequency Control Speed Regulation Experiment System Chapter I Profile I. Precautions 1. Please read this training instruction manual and related materials carefully before proceeding. This training device is equipped with dangerous voltage. It must be operated in strict accordance with the “Electrical Safety Operation Regulations" and equipment manuals specified by the State to avoid personal injury. Equipment accidents occur. 2. Although the device has multi-level protection measures, it is not allowed to short-circuit the output terminals of the power supply during operation. The current input terminals of the ammeter, power meter and power factor meter must be used in series with the load; when the load is energized, the terminal should be noted. Label the data and the range of each meter. 3. The emergency stop button is set to disconnect the total power output of the device in an emergency. Under normal circumstances, it should not be used as the power cutoff. When the emergency stop button is not reset, the total power switch of the device is not allowed to be closed. II.
