Picking power line and transmission line
■
Be sure to let the power line and the transmission line pass
through a conduit hole.
■
Pick the power line from the upper hole on the left side plate,
from the front position of the main unit (through the conduit hole
of the wiring mounting plate) or from a knock out hole to be
made in the unit's bottom plate.
(See figure 20)
Precautions when knocking out knockout holes
■
To punch a knockout hole, hit on it with a hammer.
■
After knocking out the holes, we recommend you paint the
edges and areas around the edges using the repair paint to
prevent rusting.
■
When passing electrical wiring through the knockout holes,
remove any burrs from the knockout holes and wrap the wiring
with protective tape to prevent damage.
Precautions when installing power wiring
Use round pressure terminals for connections to the power
terminal block.
When none are available, follow the instructions below.
■
Do not connect wiring of different thicknesses to the
power terminal block. (Slack in the power wiring may
cause abnormal heat.)
■
When connecting wiring which is the same thickness,
do as shown in the figure below.
■
For wiring, use the designated power wire and
connect firmly, then secure to prevent outside
pressure being exerted on the terminal board.
■
Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
■
Over-tightening the terminal screws may break them.
■
Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on
the terminal connections or wires.
Incomplete connection or fixing may cause a fire.
■
See the table below for tightening torque for the
terminal screws.
Precautions when connecting the ground
When pulling the ground wire out, wire it so that it comes
through the cut out section of the cup washer. (An
improper ground connection may prevent a good ground
from being achieved.)
1 Wiring for low noise operation level setting ( ) (optional)
2 Wiring for power consumption limitation setting ( )
(optional)
3 Wiring between the units (indoor-outdoor)
4 Fix to the indicated plastic brackets using field supplied clamping
material.
Using too much pressure on the terminal screws may
damage the PCB.

3 If there are any possibilities that small animals enter the system
through the knockout holes, plug the holes with packing materials
(to be prepared on-site).
■
Use a power wire pipe for the power wiring.
■
Outside the unit, make sure the weak low voltage
electric wiring (i.e. for the remote control, between
units, etc.) and the high voltage electric wiring do not
pass near each other, keeping them at least 50 mm
apart. Proximity may cause electrical interference,
malfunctions, and breakage.
■
Be sure to connect the power wiring to the power
wiring terminal block and secure it as described under
"Field line connection" on page 12 .
■
Inter-unit wiring should be secured as described in
"Field line connection" in chapter "8.5. Examples" on
page 12 .
• Secure the wiring with the accessory clamps so that it
does not touch the piping.
• Make sure the wiring and the electric box lid do not
stick up above the structure, and close the cover
firmly.
