6-5 Wiring connections
Remove the control box cover on the side and follow the directions to connect the wires.
〈Transmission wiring〉
Remove the control box cover and connect the wires to "TO IN/D UNIT (F1, F2)" and "TO OUT/D UNIT (F1,
F2)" terminals (printed circuit board (A1P)).
At this time, pass the wiring into the unit through the wiring through hole (left) and use the included clamps
2) to securely hold the wires (in 2 places).
〈Power supply wiring and ground wire〉
Remove the control box cover and connect the power supply wiring to the
power terminal block (X1M).
Also connect the ground wire to the ground wire terminal. Pass both the
power supply wire and the ground wire together through the wire through
hole (right) and into the control box and use the included clamps 2) to
securely hold the wires (in 2 places).
Be sure to wire the ground wire so that comes out of the slit in the cup
washer.
(Not doing so could cause insufficient ground wire contact and causing the wire not to function as a
ground.)
