1 Wiring location
The unit is constructed in such a way that wires can be connected
into the unit from the front, rear, right and bottom.
(To pass the wires from the front or the right, use the hole provided.)
2 Remove the service panel (three screws).
3 Carry out the wiring as shown below and make sure that the screws
are tightened securely.
See the figure below for each terminal block. (The wires must be
secured with clamps.)
4 Ground the unit.
5 For the thickness of the main power cable and grounding wire, refer
to page 19.
6 Use the rotary switch on the PCB (multiple controller board) for the
setting of addresses.
7 Use the grounding terminal located above each terminal in cases
where shield wires are required for the transmission cables (for cen-
tralized control, indoor/outdoor, network remote controller). (See the
figure below.)
The grounding lead wires are enclosed with this manual. (Refer to
