• The control connection between the indoor unit and the outdoor unit is made by a shielded 0.75 mm
2
cable (AWG #18),
with the shielding grounded at both the indoor unit and outdoor unit side.
• Maximum length 70 meters.
• The cable's shielding must be grounded at both ends by means of a metal clamp (not supplied) screwed onto the
terminal strip support plate.
• To avoid problems related to electromagnetic disturbances, do not route this cable near power cables.
