. These industrial devices are used to control the speed and torque of AC motors in various automation applications. HNC Electric Ltd. Quick Setup Guide Safety First

: Ensure the power supply is disconnected before wiring. For the -03 model (typically three-phase 380-440V), verify your input voltage matches the marking label. Basic Connections Input (L1, L2, L3) : Connect to the mains power supply. Output (U, V, W) : Connect to the motor.

: Always connect the grounding terminal to prevent electrical shock. Initial Power-on

: Once powered, the double-line digital display will illuminate, showing the current frequency or status. Parameter Setting

: Use the keypad (KB2 for copy functions) to navigate parameters. Key parameters include: Motor Rated Power : Set according to your motor's nameplate. Control Mode

: Choose between Open loop vector control (SVC) or V/F control. Macro Function

: Use one-key settings to save debugging time for common applications. HNC Electric Ltd.
