Connecting the pump(s)
Before connecting the pump, check whether the motor
protection switch of the control unit is suitable for the
power consumption of the pump(s) (see type plate).
If necessary, set the motor protection switch to the nomi-
nal current of the pump (see type plate of the pump).
Pull the connection cable through the cable passage(s)
and tighten in the same way as the mains cable gland.
Make connections as shown in the connection diagram.
The control unit is equipped with a terminal block. The ter-
minal pairs for the thermal contact (TF 1 and TF 2) share a
joint, middle terminal.
