User Manual of EM760 High-Performance Inverter After power-on: Δ Danger 1. Never touch the inverter and surrounding circuits with wet hands; otherwise, electric shock may occur! 2. If the indicator is not ON and the keyboard has no response after power-on, immediately turn off the power supply. Never touch the inverter terminals (R, S, T) and the terminals on the terminal block with your hands or screwdriver; otherwise, electric shock maybe caused. Upon turning offthe power supply, contact our customer service personnel. 3. At the beginning ofpower-on, the inverter automatically performs a safety test to external strong current circuits.
Do not touch the inverter terminals (U, V, W) or motor terminals; otherwise, electric shock maybe caused! 4. Do not disassemble any parts of the inverter while it is powered on. Attention 1. When parameter identification is required, please pay attention to the danger ofinjury during motor rotation; otherwise, an accident may occur! Do not change the parameters set by the inverter manufacturer without permission; otherwise, the inverter maybe damaged! 2. During operation: Δ Danger 1. Do not touch the cooling fan, radiator and discharge resistor to feel the temperature; otherwise, burns may be caused! 2.
Non-professional technicians must not test signals when the controller is in operation; otherwise, personal injury or equipment damage maybe caused! Attention 1. Prevent any object from falling into the inverter in operation; otherwise, the inverter maybe damaged! 2. Do not start or stop the inverter by turning on or off the contactor; otherwise, the inverter maybe damaged! During maintenance: Δ Danger 1. Never carry out repair and maintenance in the live state; otherwise, electric shock maybe caused! 2.
Maintenance of the inverter must be carried out 10 min after the main circuit is powered off and the display interface of the keyboard is disabled; otherwise, the residual charge in the capacitor will do harm to the human body! 3. Personnel without professional training are not allowed to repair and maintain the inverter; otherwise, personal injury or inverter damage maybe caused! 4. The parameters must be set after the inverter is replaced. Plugs in all interfaces must be operated in the power- off status! 5. The synchronous motor generates electricity while rotating.
Inverter maintenance and repair must be performed 10 min after the power supply is turned offand the motor stops running; otherwise, electric shock maybe caused! 5
