7 Electrical connection
n
Use a bus cable with this specification:
– Cable length up to 100 m: 2x2x0.22 mm²
Cable length 100 m to 200 m: 2X2x0.34 mm²
(e.g. Lapp Unitronic Bus Can, No. 2170263)
–
AWG22, STP (=Shielded Twisted Pair)
– Nominal resistance: 120 Ohm
– Line capacitance per metre: < 60 pF/m
–
Loop resistance: < 160 Ohm/km
n
Connect the shield of the bus cable to the ground
(GND
⏊
) of each electronic module (see the
images in the following chapter Bus terminator ).
n
If there are several bus subscribers, the following
applies: The bus wiring must run from one bus-par-
ticipant to the next. The order of the participants
does not matter.

7.6.3 Bus terminator resistance
– CAN (Controller Area Network) is a 2-wire bus sys-
tem. The bus must be equipped at each end with a
120Ω terminating resistor (to avoid reflections).
–
Two plugs for the CAN bus - CAN-IN and CAN-
OUT - are located on the electronics module. The
terminating resistor is pre-installed to CAN-OUT at
the factory.
– If only one electronic module is connected to the
heat pump, the terminating resistor for the
electronics module must be left on the
CAN-OUT
plug. If several modules are connected, then
the terminating resistor may only be installed
on the last module in the chain
(the terminating
resistor must be removed from the remaining
modules). See the following image(s).
