ELECTRIC WIRING
?
n o t e
• Use a shielded cable for the transmitting circuit and connect it to the ground.
• Do not use cables that are lighter than the normal flexible coated polychloroprene cable (code H05RN-F).
• The total transition wiring length between the indoor unit and the outdoor unit should be less than 1000m and the total transition wiring length
between outdoor units should be less than 30m.

Electromagnetic compatibility
• Flicker
According to Directive 2014/30/EC (2004/108/EC) regarding
electromagnetic compatibility, the following table indicates: the
maximum allowed impedance Z
point of the user's power supply, as per EN61000-3-11.

• Harmonics
In relation to IEC 61000-3-2 and IEC 61000-3-12, the situation of
harmonics for each model is as follows:
10.4 eleCtriCal WirinG for oUtDoor Unit
Connect the electrical wirings according to the following figures.
1 Connect the power supply wires to L1, L2, L3, and N (for
400V) for the three phase power source on the terminal
board TB1 and earth wire to the terminal in the electrical
control box.
2 Connect the transmission wires between the outdoor and
indoor units to the TB2 terminals 1 and 2 on the PCB1. As
for the transmission wires between outdoor units in the same
refrigerant cycle, connect them to the TB2 terminals 3 and 4
on the PCB1.

• Be sure to note to run the cables under the unit using conduit tube.
(The pipe cover needs to be removed before performing piping and
wiring works.)
• Tightly secure the power source wiring using a cord clamp inside the

Unit compliant with IEC 61000-3-2
(professional use).
(Ω)
This equipment complies with IEC
61000-3-12 provided that the short-
circuit power Ssc is greater than or
equal to xx (see Ssc column) at the
interface point between the user's
supply and the public system. It is
the responsibility of the installer or
user of the equipment to ensure,
by consultation with the distribution
network operator if necessary,
that the equipment is connected
only to a supply with a short-circuit
power Ssc greater than or equalto
xx (see Ssc column).
Installation restrictions may be
applied by supply authorities in
relation to harmonics.

n o t e
• Do not run the power supply wiring and transmission wiring through
the same conduit tube. Moreover, keep at least 5cm between the
power supply wiring and transmission wiring.
• Pull out each wiring from each corresponding knockout hole. Cut can
"X" in rubber bush (accessory) and securely attach it to the knockout
hole for cable protection. Check that the rubber bush is surely
attached.
• Attach the pipe cover to prevent rats or other small animals from
entering the unit.
• Prevent the wirings from touching or rub against the refrigerant pipes,
plate edges and electrical parts inside the unit.
• When the power source cable (cabtyre cable) whose size exceeds
38mm is used, peel the sheath part of the cable put into the unit and
2
run it. At this time, do not damage the coated insulating coated part.
• Completely seal the end of conduit tube with sealing materials to
prevent the rain from entering the conduit tube.
• Make a drain hole at the lowest part of the conduit tube.
• Fix the rubber bushes with adhesive when conduit tubes to the
outdoor unit are not used.
• Use conduit tube (field-supplied) to protect the wiring.
