• Maximum wiring length of the remote controller cable: 300 m
Even if the maximum wiring length of the product itself is specified as longer than 300 m, the
maximum length of the remote controller cable will be 300 m if the system is group-connected.
When total wiring length is longer than 100 m, the cable diameter needs to be changed as fol-
lows:

NOTES:
• Conceal the wirings of the group connection inside of the wall or by means of trunking at
the thickness of 1-mm or more to prevent electrical shocks when getting in touch with the
cables under certain circumstances.
• When using the Communication kit for wall mounted type, store the crimping terminals in-
side the Communication kit.
• In the wireless remote controllers for the group connection, its remote controller address
can be set by its own. For the details, refer to following section "Remote controller address
setting procedure for wireless remote controllers".
An error is displayed immediately just turning on the power to effect the settings of the
group connection. However the error will automatically disappear when the subsequent
function setting is completed.
• Bundle the wires with a cable tie to prevent external pressures apply on the crimping termi-
nals. (Ensure that the tensile strength for the splicing position is 10 N or above.)
