Wilo Pump TOP-S80/10

8.2 Rotation direction monitoring

Check the direction of rotation indicator light on the terminal box

If the light is not green, electrically isolate the pump and interchange 2 phases in the terminal box

Restart the pump and check the direction of rotation again

Verify that the motor's direction of rotation matches the arrow on the rating plate

Check for leaks after installation

Periodically verify all connections remain leak-free during operation

Describe any leakages of hazardous fluids and actions taken to remove them

Ensure the electrical connection is made by an approved electrician.

Disconnect all poles of the power supply before working on the pump.

Wait for 5 minutes before commencing work on the module (applies only to 1~ systems).

Check that all connections are voltage-free.

Is the module/terminal box undamaged?

Verify that the current type and voltage correspond to the rating plate specifications.

Ensure the electrical connection is via a fixed line with a connector device or an all-pole switch with a contact opening width of at least 3 mm.

Check mains-side fuse protection is 10 A, slow.

Motor Protection System Verification

Verify terminal box type and corresponding protection mechanism

Is the thermal tripping setting corresponding to the maximum current of the speed stage?

Is the Wilo tripping unit SK 602(N)/SK 622(N) present and connected?

Is the thermal winding contact (WSK) connected to a motor protection system?

Perform reset based on terminal box type

7.1 Installation / 7.1.3 Insulation

Verify the following conditions for outdoor installations and cooling/air-conditioning systems

Check that condensate drain openings are clear and unobstructed

Is the insulation applied correctly, not beyond the motor separation joint?
