REMKO CMF 320 Duo - Manual (Page 19)

Electrical connection
■
It is necessary to lay a
power-supply cable both to
the outdoor module and,
separately, to the indoor
module.
■
Power to the indoor module
may not be disconnected by
the power company. (Frost
protection)
■
The indoor modules require a
single-phase power supply at
230 V. / 50 Hz.
■
The outdoor module can be
supplied with three-phase
voltage at 400 V / 50Hz.
■
The electrical connection
between outdoor- and indoor
modules is made using four-
wire control cable.
■
Where applicable, a separate
power supply shall be provided
to the indoor module for
electric booster heating.
■
The heat-pump manager needs
to know whether a power-
company release- or off-period
is in effect. An electrically-
isolated switch must be installed
for this purpose. (An open
switch signifies power available,
an open switch, off-time.)
■
A connection schematic along
with corresponding circuit
diagrams can be found in the
appendix of this manual.
■
Special rates for heat pumps
may be offered by the power-
company (PSC).

! CAUTION
Make sure to connect the
outdoor module's neutral
connector properly, otherwise
the varistors on the line-filter
circuit board will be destroyed.
! CAUTION
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.
! CAUTION
Check all plugged and clamped
terminals to verify that they
are seated correctly and make
permanent contact. Tighten as
required.
! CAUTION
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 installation. The
information in the connection
diagram and in the system
overview are to be seen as an
acceptable installation possibility
only in a standard case!
