4.3 Connecting the wastewater pump(s)
1 Before connecting the pump, check whether the control unit's motor
protection switch is suitable for the current consumption of the pump(s) (see
nameplate).
▶ Adjust the motor protection switch to the pump's nominal current (see
pump's nameplate)
▶ Pull the connection cable through the housing opening(s).
▶ Establish the connections in accordance with the connection diagram (in
the housing cover of the control unit).
The control unit has a terminal block in which the terminal pairs for the thermal
contact (TF 1 and TF 2) share a common terminal in the middle.
