NOTICE:
• Thermal contacts are incorporated in the pump.
• Thermal contacts must never be exposed to voltages higher than 250 V, breaking
current maximum 4 A. It is recommended that they are connected to 24 V over
separate fuses to protect other automatic equipment.
The single phase pumps must be equipped with a starter which has start and run
capacitors.
1. If thermal contacts are included in the pump installation, connect the T1 and T2 control
conductors to the monitoring equipment.
NOTICE:
Ex-approved products must always have the thermal contacts connected irrespective
of the ambient temperature.
2. Connect the mains leads (L1, L2, L3, and earth [ground]) to the starter equipment.
