System overview of field wiring
■
Most field wiring on the indoor unit side is to be made on the
terminal block inside the switch box. To gain access to the
terminal blocks, remove switch box service panel. Refer to the
unit switch box cover for instructions how to remove this panel
and gain access to the inside of the switch box.
■
Cable tie mountings are provided at the wiring entries of the
switch box. See
"Switch box main components" on page 7 .
Connection of the indoor unit power supply and
communication cable(s)
Cable requirements
Procedure
1 Using the appropriate cable, connect the power supply and
communication cable(s) to the appropriate terminals as shown
on the wiring diagram and according to
figure 3 .
2 Fix the cable with cable ties to the cable tie mountings to ensure
strain relief and to make sure that it does not come in contact
with the piping and sharp edges. Never squeeze bundled
cables.
Note: only relevant field wiring is shown in figure 3 .
NOTE
■
The electrical connection diagram can be found
on the inside of the switch box cover.
■
Install the indoor and outdoor unit, power supply
cable and communication cable(s) at least 1
meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1
meter may not be sufficient to eliminate the
noise.)

NOTE Select all cables and wire sizes in accordance with
relevant local and national regulations.
After finishing the electric work, confirm that each electric
part and terminal inside the electric parts box is connected
securely.
■
To avoid receiving electric noise, be sure that the
cables are put in the correct bundle and routed in
the correct bundle tray as shown in
figure 3 .
■
When wiring, route the cable bundles away from
each other by at least 25 mm in order to avoid
receiving electric noise (external noise).
