7.3 Control Cable Length
● Maximum power supply cable length ( L1 + L2, L1 + L3, L1 + L4 + L5 ) : the longest length of the cable from the power supply
unit or the indoor unit of air conditioner to the farthest terminal cannot be more than 200 m.
● Maximum distance between ends ( L2 + L3 + L5, L2 + L4, or L3 + L4 + L5 ) : the length of cable from end to end of units cannot be more
than 500 m.
● Remote controller cable length (
more than 10 m.

Power supply unit
Centralized remote controller
Outdoor unit
Notes:
● Always install the ground cable for the transmission cables by routing the central control system through the power supply
unit, then routing the indoor unit system through the ground terminal on the outdoor unit.
● If the cable length (
R
) for the remote controller exceeds 10 m, use a cable with a 0.75 mm
exceeding 10 m to a cable with a diameter of 1.25 mm
imum power supply cable length" restriction of 200 m and the "maximum distance from ends to ends of units" restriction of 500 m.
● If the cable exceeds the maximum cable length and overall extended length, voltage will drop and cause the system to mal-
function.
