Fixing of Power Supply Cord
and Connecting Cable
1. Connecting cable between Indoor Unit and
Outdoor Unit shall be approved polychloroprene
sheathed 4 × min 4.0 mm
2
flexible cord, type
designation 60245 IEC 57 or heavier cord.
Ensure the colour of wires of Outdoor Unit and
the terminal no. are the same to the Indoor
Unit respectively.
Earth wire shall be longer than other wires as
shown in the figure for the electrical safety in
case of the slipping out of the cord from the
Holder (Clamper).
2. An isolating device must be connected to the
power supply cable.
Isolating device (disconnecting means) should
have minimum 3.0 mm contact gap.
Connect the approved polychloroprene
sheathed power supply 1 cord and power
supply 2 cord and type designation 60245 IEC
57 or heavier cord to the terminal board, and
to the other end of the cord to isolating device
(Disconnecting means). See below table for
cable size requirement.

3. To avoid the cable and cord being damaged by
sharp edges, the cable and cord must be passed
through a bushing (located at the bottom of
Control Board) before terminal board. The bushing
must be used and must not be removed.

The equipment's power supply 1 complies with
IEC/EN 61000-3-12 provided that the short circuit
power S
SC
is greater than or equal to 2200 kW at
the interface point between the user's supply and
the public system. It is the responsible 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 short circuit power S
SC
greater than or equal to 2200 kW.
The equipment's power supply 1 complies with
IEC/EN 61000-3-11 and shall be connected to a
suitable supply net work, having service current
capacity
≥
100A per phase. Please liaise with
supply authority that the service current capacity
at the interface point is sufficient for the
installation of the equipment.
The equipment's power supply 2 complies with
IEC/EN 61000-3-12.
The equipment's power supply 2 complies with
IEC/EN 61000-3-11 and shall be connected to
suitable supply network, with the following
maximum permissible system impedance Z
max
=
0.271
Ω
at the interface. Please liaise with supply
authority to ensure that the power supply 2 is
connected only to a supply of that impedance or
less.
