How to Install

• The first thing to do during installation is to select an appropriate site. It should be clean and dry, and frequent temperature extremes will not be good for the AFD. Installation should allow for forced cooling and good airflow around the adapter.
• Next, prepare the electrical connection by shutting off the main power, as any accident will damage the user or the equipment. Then, connect the input power wires to the designated terminals on the AFD.
• Afterward, connect the output wires by connecting the motor leads from the frequency converter to the designated terminals. Users should ensure they are using the correct wiring diagram to achieve a proper connection.
• For optional users, install a remote potentiometer or control panel if the frequency converter will be operated remotely. This should be done before doing the main adjustment since it will be easier to adjust control settings.
• Finally, power up the frequency converter and set the output frequency to zero. This will prevent any sudden motor from starting up.

How to Use

• The first step to using a frequency inverter is to power the unit on by turning the main power switch. This will allow the user to set required frequency and voltage parameters.
• The next step is to connect the input power wires to the terminals designated at the AFD.
• Using the control interface, the user can set motor specifications such as rated voltage and frequency. He can also set other parameters such as acceleration and deceleration time to ensure smooth motor operation.
• The user should jog the motor at low speed to confirm that all the connections are correct and everything is working as expected. After the motor is properly connected and all set, the output frequency can be gradually increased to operate the connected load.
• While in operation, users are advised to periodically check the AFD for overheating or any other abnormal signs. Proper and regular checking prolongs the drive and equipment's life while ensuring reliable operation.
