To connect the power supply
• Two cables must be connected to the outdoor unit
– The communication cable between the indoor and outdoor
unit.
– The power cable between the outdoor unit and the
auxiliary breaker.
• Especially for the Russian and European market, before
installation, the supply authority should be consulted
to determine the supply system impedance to ensure
compliance.
CAUTION
• You should connect the power cable into the power cable terminal
and fasten it with a clamp.
• The unbalanced power must be maintained within 2% of the
supply rating.
– If the power is unbalanced greatly, it may shorten the life
of the electrical components. If the unbalanced power
is exceeding 4% of the supply rating, the control kit is
protected, stopped and an error code is displayed.
• To protect the product from water and possible shock, keep
the power cable and the connection cord of the control kit
and outdoor units within ducts (with appropriate IP rating and
material selection for your application).
• Ensure that the main supply connection is made through a
disconnection switch within your arm's reach, that disconnects all
poles, with contact gap of a least 3 mm.
Route the cable through the frame
• Connect the wires to the terminal block and fix the cable with
the cable tie.

• When installing electrical wiring: tension on the cable(s) must
be avoided.
• Earth wire for the indoor unit and outdoor unit cables must be
clamped to a suitable ring terminal clamp (not supplied)
• For the power cable, use the grade H07RN-F or H05RN-F
materials.
• Power supply cords of parts of appliances for outdoor unit use
shall not be thinner than polychloroprene sheathed flexible
cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F
or IEC:60245 IEC 66 / CENELEC: H07RN-F)
To connect the communication cable
• The communication cable between the indoor and outdoor
unit.
• Route the cable through the frame.
• Connect the wires to the terminal block and the earth screw
(single side, the other end of the protective shield is not again
connected to earth).
• Fix the cable with a cable tie.
