2.2 General notes
n
A mains power line must be routed to the
indoor module.
n
The indoor module HTS 90 needs to have a
one-phase power supply from 230 V / 1~/50 Hz
and the indoor modules HTS 130/200/260
need to have a three-phase power supply from
400 V / 3~/50 Hz.
n
The electrical connection between outdoor-
and indoor modules by means of several con-
trol lines.
n
A connection schematic along with corre-
sponding circuit diagrams can be found in the
'Connection diagram' chapter of this manual.
n
If an auxiliary electric booster heating is
needed in the indoor module one three-phase
power supply 400 V / 3~/50 Hz shall be pro-
vided.
n
Power to the indoor module may not be discon-
nected by the power company when fitted with
an off-period circuit (anti-freeze protection).
n
The Smart-Control needs to know whether a
power-company release- or off-period is in
effect (contact S16). An electrically-isolated
switch must be installed for this purpose. (con-
tact closed signifies release, while contact
open signifies an off-period).
n
Special rates for 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!
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.
