EM500 Open-Loop Vector Control Inverter User Manual power. 3. After being powered on, inverter will automatically check the safety of the external strong circuit automatically. Therefore, do not touch wiring terminal U, V or W of inverter or the wiring terminal of the motor with bare hands, otherwise it will result in electric shock. Caution If you need to check parameter settings, be careful of personal safety when the motor is running so as to avoid accidents. Do not change default parameter setting without approval to avoid damage. During Operation: Danger Never touch cooling fan, heat sink or discharge resistor with bare hands for checking temperature, which may result in burning!
Only qualified technicians are allowed to detect signal during operation so as to prevent personal injury or device damage. Caution Prevent any foreign items from being dropped into the device during operation, so as to avoid damage to the device. Do not control the start/stop of inverter by ON/OFF of the contactor so as to avoid damage to the device. Maintenance: Danger Maintain and inspect the device only after inverter is powered off for at least 10 minutes to avoid electric shock. Maintain and inspect inverter only after its main circuit is powered off and CHARGE indicator is off. Otherwise, the residual electric charge of capacitor may result in personal injury.
Maintenance and inspection can be performed by well-trained technicians only, so as to avoid personal injury or device damage. Parameter setting is required if inverter has been replaced. Plug-in & plug-out should be 5
