Pump start and cable check

Check the cable for damage and that there is no water or corrosion in the connecting plug. 

 

Test the insulation between cable end / plug and earth.

 

Check if the pump starts by connecting it to the power supply.

2.3 

Dismantling cover

Unscrew and lift off the cover and disconnect the power cables from the contactor/terminal block. 
If the water has penetrated through the cable gland and the cable seal, the cable gland and the cable seal should be re-

placed. Remove strain relief clamp prior to unscrewing cable gland body. Pull out cable, cable gland, washer and unscrew 

the cable seal.
