NOTE
º
ºººº
The DIP switches on the circuit boards in the outdoor unit
have no function. The positions of the DIP switches must
remain in their factory default and must not be changed!
Two cables must be connected on the outdoor unit:
A 'mains cable' and a 'data cable'
Both cables must be laid between the indoor and outdoor unit.
The mains cable is used to supply the outdoor unit with power
and the data cable is for communication between the outdoor
and indoor component. The VDE directives and regulations and
local conditions must be taken into account in the design and
installation of the two cables.
The indoor component already contains a safeguard element
for the outdoor component. The safeguarding of the entire heat
pump must also take place externally.
For LAK 3IMR, LAK 6IMR, LAK 9IMR, LAK 14IMR:
The mains cable on the outdoor unit must be three-core and
must be connected to the L / N / PE (power supply) terminals.
(See Cap. 3.2 on page XII; Cap. 3.5 on page XV and Cap. 3.8 on
page XVIII)
For LAK 14ITR
The mains cable on the outdoor unit must be 5-core and must
be connected to the R / S / T / N / PE terminals (see Cap. 3.5 on
page XV)
If no connection lugs are available, proceed as follows.
No cables with different thicknesses may be connected to
the connecting terminal. (one of the cables may come
loose during strong heat development.)
Multiple cables of the same thickness must be connected
as shown in the figure.
A shielded 2-core cable must be used as a data cable.
The data cable is connected to the terminals (Bus_A(+) /
Bus_B(-)) of the gateway circuit board (small circuit board in the
outdoor component) and to the heat pump manager (+/-) in the
indoor component (see Appendix, Connection diagram Chap.
2.5).
