X wiring : 215mm
Y wiring : 195mm
Install the upper case as before so as not to catch up the remote control cord, and tighten with
the screws.
In case of exposing cord, fix the cord on the wall with cord clamp so as not to slack.
Wiring of remote control should use 0.3mm
Maximum prolongation of remote control wiring is 600 m.
If the prolongation is over 100m, change to the size below.
But, wiring in the remote control case should be under 0.5mm
the case according to wire connecting. Waterproof treatment is necessary at the wire connecting
section. Be careful about contact failure.
100 - 200m ......................... 0.5mm
