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
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.

MODELS SITUATION
REGARDING IEC 61000-3-2 AND
IEC 61000-3-12 Ssc "xx" (kVA)
Unit compliant with IEC 61000-3-2
(professional use).
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.
