Supplement to Installation and Operating Instructions
1.
Replacement/shortening of motor cable
The submersible drop cable must be complete and without cable joint from the motor to the converter.
A previously connected cable must be fitted with a new cable kit before it can be reused. See 3. Shortening
of motor cable.

Replacement of motor cable
Slacken and remove the screw, pos. 215a, together with the strainer,
pos. 215. See fig. 1.
Screw the pump housing, pos. 201a, (right-hand thread) off the suction
interconnector, pos. 214. Pull the pump housing and the impeller
assembly, pos. 200, off the motor shaft.
Push the impeller assembly out of the pump housing from the
discharge side.
Slacken the screw, pos. 20k, for the earth lead and pull it off the
screw, pos. 222a, together with the earth lead and the washers, pos.
20d and 20f.
Slacken and remove the screws, pos. 222 and 222a
Pull the suction interconnector, pos. 214, off the motor.
Slacken and remove the screws, pos. 20b, holding the motor cable.
Pull the motor cable off the motor.
Screw positions 20d and 20e out of the motor using a small screwdriver
and precision electronic pliers.
Before fitting the motor cable, clean the holes in the motor.
Pull positions 20b, 20d and 20e on the three leads (phases) of the motor
cable. On the earth lead (yellow/green), the order is pos. 20k, 20d and 20f.
See fig. 1.
Bend the stripped end of the earth lead. See fig. 1.
When fitting the plugs in the motor, the first plug can be fitted arbitrarily.
Then it is very important that the colour sequence is correct. Clockwise the
order is black - blue - brown. See fig. 2.
Push the plug of the lead into the plug of the stator. Then press positions 20e and 20d around the lead and
tighten by means of the screw, pos 20b.
Fit the suction interconnector, pos. 214, to the shaft and secure it to the motor with the screws, pos. 222 and
222a.
