Key specifications

• Power range: 3 to 4 kW
• Operating current: 6.6 to 8.5 A
• Control voltage: 24V DC
• Mounting type: Busbar mounting

How to use

Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The unit is designed to be mounted directly onto a compatible busbar system. Ensure that the power supply is disconnected before beginning the installation. Connect the motor leads and the 24V DC control signal wires to the designated terminals, verifying that all connections are secure and properly tightened to prevent overheating. Once installed, perform a functional test to ensure the motor starts and stops according to the control signal.

What to consider before purchase

• Verify that your motor power and current ratings fall within the specified ranges.
• Ensure your control system provides a stable 24V DC supply.
• Confirm compatibility with your existing busbar system dimensions.
• Check that the installation environment meets the required temperature and humidity standards for industrial electrical equipment.

Usage recommendations: Regularly inspect the terminal connections for tightness and check for any signs of thermal stress or debris accumulation to maintain optimal performance and safety.
