Connecting the electrical wiring

DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.
WARNING
▪ Do NOT use locally purchased electrical parts inside
the product.
▪ Do NOT branch the power supply for the drain pump,
etc. from the terminal block. This could result in
electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes
without thermal insulation as such pipes will be very hot.
5.4.1 To connect the electrical wiring on the
indoor unit
Electrical work should be carried out in accordance with the
installation manual and the national electrical wiring rules or code of
practice.
It is important to keep the power supply and the transmission wiring
separated from each other. In order to avoid any electrical
interference the distance between both wirings should ALWAYS be
at least 50 mm.
NOTICE
Be sure to keep the power line and transmission line apart
from each other. Transmission wiring and power supply
wiring may cross, but may NOT run parallel.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.

6.2

Checklist before commissioning

Do NOT operate the system before the following checks are OK:
You read the complete installation instructions, as
described in the installer reference guide.
The indoor units are properly mounted.
The outdoor unit is properly mounted.
Air inlet/outlet
Check that the air inlet and outlet of the unit is NOT
obstructed by paper sheets, cardboard, or any other
material.
There are NO missing phases or reversed phases.
The refrigerant pipes (gas and liquid) are thermally
insulated.
Drainage
Make sure drainage flows smoothly.
a
Possible consequence: Condensate water might drip.
b
The system is properly earthed and the earth terminals
are tightened.
c
The fuses or locally installed protection devices are
installed according to this document, and have NOT been
bypassed.
The power supply voltage matches the voltage on the
identification label of the unit.
The specified wires are used for the interconnection
cable.
The indoor unit receives the signals of the user interface.
