ELECTRIC WIRING

Electromagnetic compatibility
According to Directive 2004/108/EC (89/336/EEC) 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:
Situation of the models in relation to IEC 61000- 3-2 and IEC 61000-3-12 Ssc "xx"
Unit compliant with IEC 61000-3-2 (professional use).
Unit compliant with IEC 61000-3-12.
This unit is in accordance with Standard IEC 61000-3-12 with the condition that the short circuit
current Ssc is greater than or equal to xx (see Ssc column) at the connection point between the
power supply of the user and the public grid. It is the responsibility of the installer or the user of
the unit to ensure, if necessary consulting the distribution grid operator, that the unit is connected
only to a power supply where the short circuit power is greater than or equal to xx
(see Ssc column).
The authorities responsible for the electrical power supply can apply restrictions relating to
harmonics.
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.

C A U T I O N
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.

• 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.
