2.2 Electrical wiring general notes

n A power supply cable must be laid to both to
the outdoor unit and, separately, to the Smart
Control.
n Power to the smart control may not be discon-
nected by the power company when fitted with
an off-period circuit (anti-freeze protection).
n All Smart Controls require a single-phase
230V/50Hz power supply.
The outdoor units require a single-phase
400V/50Hz power supply.
n The electrical connection between outdoor and
indoor units is made using a sheathed dual
control line.
n If necessary, another three-phase 400V/50Hz
power supply to the outside unit for electrical
auxiliary heater / Smart-Serv must be provided.
n The Smart-Control needs to know from the
power-company whether the power supply is
enabled or a blocking period is in effect. A
potential-free switch must be installed by the
customer for this purpose. (Contact closed sig-
nifies enabled, while contact open signifies a
blocking period).
n A connection schematic along with corre-
sponding circuit diagrams can be found in the
"Electrical layout" and "Circuit plans" chapters
of this manual.
n Special rates for the operation of heat pumps
may be offered by the power-company (utility).
n Ask your local power company about the
details of any rates that might be available.
DANGER!
All electrical installation work must be done by
an electrician.
WARNING!
Always note the currently applicable VDE
guidelines and the notes in TAB 2007. The size
and type of the fuse are to be taken from the
technical data.

WARNING!
All cable sizes are to be selected according to
VDE 0100. Special attention should be given to
cable lengths, cable type and the kind of instal-
lation. The information in the connection dia-
gram and in the system overview are to be
seen as an acceptable installation possibility
only in a standard case!
NOTICE!
Make sure to connect the outdoor unit neutral
connector properly, otherwise the varistors on
the line-filter circuit board will be destroyed.
NOTICE!
The electrical connection for the units must be
made at a separate feedpoint with a residual
current device in accordance with local regula-
tions and should be laid out by an electrician.
Check all plugged and clamped terminals to
verify that they are seated correctly and make
permanent contact. Tighten as required.
