For 100, 125, 140Y application, use shield wire. (For EMC DIRECTIVE)
The shield part must be grounded with the indoor unit or the outdoor unit, not with both.
When the shield line is not used, several dB is exceeded with 30 ~ 40 MHz .
(There is a possibility to be used by the wireless for the ship etc. though it is not used for radio and TV.)
Be sure to connect the indoor-outdoor connecting cables directly to the units (no intermediate connections).
Intermediate connections can lead to communication errors if water enters the cables and causes insufficient
insulation to ground or a poor electrical contact at the intermediate connection point.
(If an intermediate connection is necessary, be sure to take measures to prevent water from entering the cables.)
