After you have connected the motor cable to the pump, connect the motor cable and the
control cable to the starter equipment.
WARNING:
Do not install the starter equipment in an explosive zone or in the sump.
Three thermal contacts are incorporated in the stator. They are normally closed.
Thermal contacts must never be exposed to voltages higher than 250 V, breaking current
maximum 6 A at a power factor 0.6. It is recommended that the thermal contacts are
connected to 24 V over a separate fuse to protect any other automatic equipment.
