WARNING:
Do not install the starter equipment in an explosive zone unless it is explosion-proof rated.
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.
