6.4 Fitting the cable plug to the motor 

The cable plug supplied with the motor is factory-
greased. Check that the plug is greased correctly. 

To fit the cable plug, proceed as follows:

1. Check that the cable is of the correct type, cross-

section and length.

2. Check that the mains on the location has correct 

connection to earth.

3. Check that the motor socket is clean and dry.

Make sure that the loose gasket has been fitted.

4. Press the cable plug onto the motor socket. 

The plug cannot be fitted wrongly. See fig. 8.

Fig. 8

5. Fit and tighten the four screws (1 - 1.5 Nm). 

See fig. 8

When the plug has been fitted, there must not be a 
clearance between the motor and the cable plug.

6.5 Fitting the cable guard

To fit the cable guard, proceed as follows:

1. Make sure that the submersible drop cable lies 

flat in the cable guard.

2. Place the cable guard in the groove in the cable 

plug. The two flaps of the cable guard must 
engage with the upper edge of the pump sleeve. 
See fig. 9.

Fig. 9

3. Fasten the cable guard to the pump suction 

strainer with the two self-tapping screws 
supplied. See fig. 10.
