  3. Motor connections: Connect motor to U, V, W terminals.
  4. Control wiring: Connect control signals to appropriate terminals.
  5. Grounding: Ensure proper grounding to terminal.

WARNING! High voltage present - disconnect power before installation. Ensure proper grounding to prevent electric shock.

First-Time Setup

Power on inverter; configure basic parameters.

  1. Motor parameters: Set motor rated current, voltage, and frequency.
  2. Acceleration/deceleration: Set appropriate ramp times for application.
  3. Frequency reference: Select source (digital operator, analog input, communication).
  4. Run command: Select source (digital operator, external terminals, communication).
  5. Protection settings: Configure overload protection and other safety parameters.

CAUTION! Verify all settings before starting motor. Incorrect parameters may cause equipment damage.

Specifications
