55 Installation of Outdoor Units
•
Transmission line: Connect it using a conduit in the
knockout hole on the right as shown in the following fig-
ure:
•
Use a power-wire pipe for the power wiring.
•
Outside the unit, make sure the low-voltage electrical
wiring, such as the remote controller, and the high-volt-
age electrical wiring, do not cross, keeping them at least
5 inches apart. Proximity can cause electrical interfer-
ence, malfunction, or damage.
•
Be sure to connect the power wiring to the power wiring
terminal block and secure with acessory clamps so that
it not touch piping as described in
Field line connec-
tion , page 53.
•
Make sure the wiring and the electric parts box lid do not
stick up above the structure, and close the cover firmly.
CAUTION
•
Never connect power supply wiring to the terminal block
designated specifically for remote controller wiring as this
could damage the entire system.
•
The wiring from the indoor units must be connected to the
F1/F2 (In-Out) terminals on the PC board in the outdoor
unit. Always use vinyl cords with AWG 18-16 sheath, or 2-
core wire cables.
For multiple outdoor units:
•
The interconnecting wiring between the outdoor units in the
same pipe line must be connected to the Q1/Q2 (Out Multi)
terminals. Connecting the wires to the (Out-Out) terminals
results in system malfunction.
•
The wiring for the other lines must be connected to the F1/
F2 (Out-Out) terminals of the P-board in the outdoor unit to
which the interconnecting wiring for the indoor units is con-
nected.
•
Interconnecting wiring runs from all indoor units to the out-
door base unit.
•
The interconnecting wiring between the outdoor units must
be a maximum of 100 feet.
•
Over-tightening the terminal screws may break them and
50.
NOTE
•
Be sure to keep the power line and transmission line sep-
arate.
•
The transmission line is not polarity sensitive.
•
Make sure that the transmission line is clamped as shown
in the above figure. See
Field Line Connection on page
53.
•
Check that wiring does not make contact with refrigerant
piping and arrange electric wires so you can firmly close
the lid and prevent parts from coming loose.
10.3 BEFORE OPERATION
Check the following after completion of work:
CAUTION
•
Never connect power supply wiring to the terminal block
for remote controller wiring as this could damage the en-
tire system.
•
Attach the power wire securely.
•
To avoid injury, always make sure that the circuit breaker
on the power supply panel of the installation is switched
off before doing any work.
After the installation, check the following before switching on
the circuit breaker:
1. Position of Switches: The position of the switches requir-
ing an initial setting must be set according to your applica-
tion needs before turning the power supply on.
Use a designated power supply and transmission wiring
and make sure that it has been carried out according to the
instructions described in this manual, the wiring diagrams
and local and national regulations.
Correct Pipe Sizes: Make sure that correct pipe sizes are
installed and that the insulation work is properly executed.
2. Additional Refrigerant Charge:
The amount of refrigerant to be added to the unit should be
written on the included [
Additional Refrigerant ] label, and
attach it to the rear side of the front cover.
3. Measurement of Insulation in Main Power Circuit:
Using a megatester for 500V, check that the insulation
resistance of 2MW or more is attained by applying a volt-
