WIRING EXAMPLE AND HOW TO SET
THE REMOTE CONTROLLER

HOW TO CONNECT WIRINGS

(Remove the electrical components box lid and wire as shown in
the figure below.)

Routing power supply wiring and transmission wiring

Let the power supply wiring with a conduit pass through one of
the holes on the side cover, and let the transmission wiring with
a conduit pass through another hole.

• For protection from uninsulated live parts, thread the power

supply wiring or the transmission wiring through the included
insulation tube and secure it with the included clamp.

CAUTION

• Be sure to attach the sealing material or putty (field supplied)

to hole of wiring to prevent the infiltration of water as well as
any insects and other small creatures from outside. Other-
wise a short-circuit may occur inside the electrical compo-
nents box.

• When clamping the wires, be sure no pressure is applied to

the wire connections by using the included clamping material
to make appropriate clamps. Also, when wiring, make sure
the lid on the electrical components box fits snugly by arrang-
ing the wires neatly and attaching the electrical components
box lid firmly. When attaching the electrical components box
lid, make sure no wires get caught in the edges. Pass wiring
through the wiring through holes to prevent damage to them.

• Make sure the remote controller wiring, the wiring between

the units, and other electrical wiring do not pass through the
same locations outside of the unit, separating them by at
least 2in., otherwise electrical noise (external static) could
cause mistaken operation or breakage.

[ PRECAUTIONS ]

Use round crimp-style terminals for connecting wires to the
power supply terminal block.

If unavailable, observe the following points when wiring.
• Do not connect wires of different gauge to the same

power supply terminal.
(Looseness in the connection may cause overheating.)

• Use the specified electric wire. Connect the wire securely to

the terminal. Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 0.97ft·lbf ±10 %)

2. Tightening torque for the terminal screws.

• Use the correct screwdriver for tightening the terminal

screws. If the blade of screwdriver is too small, the head
of the screw might be damaged, and the screw will not be
properly tightened.

• If the terminal screws are tightened too hard, screws

might be damaged.

• Refer to the table below for the tightening torque of the

terminal screws.

3. Do not connect wires of different gauge to the same ground-

ing terminal. Looseness in the connection may deteriorate
protection.

4. Outside of the unit, keep transmission wiring at least 2in.

away from power supply wiring. The equipment may mal-
function if subjected to electrical (external) noise.

5. For remote controller wiring, refer to the “INSTALLATION

MANUAL OF REMOTE CONTROLLER” attached to the
remote controller.

Never connect power supply wiring to the terminal
block for remote controller wiring. A mistake of the sort
could damage the entire system.

7. Use only specified wire and tightly connect wires to terminals.

Be careful wires do not place external stress on terminals.
Keep wiring in neat order and so as not to obstruct other equip-
ment such as popping open the electrical components box lid.
Make sure the lid closes tight. Incomplete connections could
result in overheating, and in worse case, electric shock or fire.
