2. If thermistors are included in the pump installation, and screened or auxiliary cable is
used, then connect T1(1) and T2(2) to thermistor relay, and T3(3) and T4 (4) to
MiniCAS II.
3. Connect the mains leads (L1, L2, L3, and ground (earth) ) to the starter equipment.
For information about the phase sequence and the color codes of the leads, see
