WARNING: Electrical Hazard
If the power cable is jerked loose, then the ground (earth) conductor must be the last
conductor to come loose from its terminal. Make sure that the ground (earth) conductor is
longer than the phase conductors at both ends of the cable.
WARNING: Electrical Hazard
Risk of electrical shock or burn. You must connect an additional ground- (earth-) fault
protection device to the grounded (earthed) connectors if persons are likely to come into
contact with liquids that are also in contact with the pump or pumped liquid.

1. Peel off the outer jacket at the end of the cable.
2. Prepare the control element:
a) Peel the insulation jacket or plastic jacket.
b) Peel the aluminum and textile layers.
The aluminum foil is a conductive screen. Do not peel more than necessary, and
remove the peeled foil.
