7. Electrical Connection

Warning! Ensure that the voltage values of your installation
correspond to the voltage values given on the device´s specification
plate.

•

  Make sure that the electrical power supply is off.

•

  Connect the sensor cable to terminals 6 & 8 on the setting system.

•

  Connect the power supply (voltage supply) to terminals 15 & 16.

Temperature relay only on models
KAL-E3.
The relais are illustrated in fallen state.

AC voltage supply
