NOTICE
▪ Be sure to keep the power line and transmission line
apart from each other (≥50 mm). Transmission wiring
and power supply wiring may cross, but may not run
parallel.
▪ Transmission wiring and power supply wiring may not
touch internal piping in order to avoid wire damage due
to high temperature piping.
▪ Firmly close the lid and arrange the electrical wires so
as to prevent the lid or other parts from coming loose.
Low voltage wiring ▪ DIII transmission wiring
▪ Remote switches (operation, low
noise)
High voltage wiring ▪ Output signals (caution, warning,
run, operation)
