 Operation
Danger Danger
 Power supply can only be connected after the wiring is completed and the cover is
installed. It is forbidden to remove the cover in live condition; otherwise, electric shock
may happen.
 When automatic fault reset function or restart function is enabled, isolation measures
shall be taken for the mechanical equipment, otherwise, personal injury may be caused.
 When the inverter is power on, its terminals are still live even when in stop state. Do not
touch the inverter terminals; otherwise electric shock may happen.
 The fault and alarm signal can only be reset after the run command has been cut off.
Otherwise, personal injury may be caused.
Note Note
 Do not start or shut down the inverter by switch on or off the power supply, otherwise,
the inverter may be damaged.
 Before operation, please confirm whether the motor and equipment are in the allowable
use range, otherwise, the equipment may be damaged.
 The heat-sink and the braking resistor have high temperature. Please do not touch such
device; otherwise, you may be burnt.
 When it is used in the application of crane or lifting equipment, mechanical brake should
also be equipped.
 Please do not change the inverter parameters randomly. Most of the factory settings
can meet the requirement, and the user only needs to set some necessary parameters.
Any random change of the parameter may cause the damage of the mechanical
equipment.
 In the applications of changeover between power frequency and variable frequency, the
two contactors for controlling the changeover between power frequency and variable
frequency must be interlocked.
 Maintenance, Inspection
Danger Danger
 In the power−on state, please do not touch the inverter terminals; otherwise, electric
shock may happen.
 If the cover is to be removed, the power supply must be disconnected first.
 Waiting for at least T0 minutes after power off or confirm that the CHARGE LED is off
before maintenance and inspection to prevent the human injury caused by the residual
voltage of the electrolytic capacitor in main circuit.
 The components shall be maintained, inspected or replaced by qualified electricians.
