Connection of the electric plate to an external control box
• Install an RC filter on the KM1 coil.
• Install an RC filter on the KM2 coil.
• All connections between external parts and the compressor must be carried out using a shielded cable, which must be
grounded at one of its ends.
WARNING: the operation connection cables between the different elements must never follow the same path
as the existing power cords. A separate installation from the power cords must be carried out.
• Install an RC filter on all the relay coils of the external operation units.
