How to use
To use the LUCB05BL, insert the control unit into a compatible TeSys U power base (LUB12, LUB32, or LUB38). Ensure the power base is properly mounted and wired according to the technical documentation. Connect the 24V DC control signal to the A1/A2 terminals located on the power base. Once installed, adjust the current setting dial to match the nominal current of your motor to ensure accurate overload protection. Always verify that all connections are secure before energizing the system.
What to consider before purchase
Verify compatibility with your existing TeSys U power base
Ensure the motor's nominal current falls within the 1.25-5A range
Confirm the availability of a 24V DC control supply
Check the environmental conditions to ensure IP40 protection is sufficient
Usage recommendations: Regularly inspect the control unit for signs of wear or loose connections during routine maintenance. Ensure that the current setting is correctly calibrated to the motor's nameplate data to prevent nuisance tripping or inadequate protection.
