13.1 SAFETy PRECAUTIONS

DANGER!
Danger of electric shock.
Before connecting the unit to the electric supply line,
ensure that the line is not live.
DANGER!
Danger of electric shock.
If the mains cable is damaged, it must be replaced
by the manufacturer, the head of maintenance or a
similarly qualified person.
DANGER!
Danger of electric shock.
Ensure that the power line is equipped with a bipolar
or tetrapolar switch according to the model, (single
phase or three-phase) with a distance of at least 3 mm
between contacts (Standard EN-60335-2-40).
DANGER!
Danger of electric shock.
Equip the installation with protection against short-
circuits to avoid electric shocks. This is a legal
requirement.
DANGER!
Danger of electric shock.
Use an electric plug which perfectly adapts to the
electric power supply wiring.
DANGER!
Danger of electric shock.
Use wiring in accordance with the respective local,
national and international wiring standards regarding
installation in technical electrics.
DANGER!
Danger of electric shock.
Use an approved electric plug and power supply cable.
WARNING!
Danger of breakdowns or malfunction.
Size the electric wiring with sufficient capacity.
WARNING!
Danger of breakdowns or malfunction. Compliance with
the Standard EN 61000-3-11: Check that the nominal
power of the main phase current connection is > 100.
WARNING!
Danger of breakdowns or malfunction.
Ensure that the supplied power voltage is in the range
of 90% to 110% of the rated voltage.
WARNING!
Install the unit in such a way that the electric plug is
easily accessible. Thus, if required, the unit can be
quickly disconnected.

13.2 REMARK WITH REGARD TO DIRECTIVE 2004/108/CE

In order to prevent electromagnetic interference during the
start up of the compressor (technical process), the following
installation conditions must be adhered to.
• Make the air conditioning unit power supply connection at
the main power distribution. Carry out the distribution with
low impedance. Normally the required impedance is
reached at a  A fusing point.
• Check that no other equipment is connected to this power
supply line.
NOTE!
For more detailed information on the electric
installation, please consult the Technical Connection
Conditions applied by your electricity supply board.
NOTE!
In order to obtain more information with regard to
power details of the air conditioner consult the unit
rating plate.
