3.4 APPLICABLE WIRING

Make sure to use applicable wiring as the following items.

wire that is shield less than 0.5mm2.

￿Connect the wire which peeling length of sheathed signal wire is 5 –

￿In case of connecting twist wire, make sure not to loose￿

￿Use signal wire which max, outside diameter is less than 2.0mm2
