Electrical installation work
for the extension box
4.1 Electrical installation work
1)
The three-core electrical supply cable for the extension
box (N17) is fed into the heat pump (device with integrated
controller) or to the future mounting location of the heat
pump manager (WPM).
The (L/N/PE~230 V, 50 Hz) supply cable for the extension
box must have a continuous voltage. For this reason, it
should be tapped upstream from the utility blocking con-
tactor or be connected to the household current, as impor-
tant protection functions
may otherwise be lost during a utility block.
2)
It is connected to either the -N1/MH X1.2 230V: OUT con-
nector in the heat pump manager (WPM) or directly to the
extension box (N17). The extension box itself is connected
at the -N17/HV X1 230V IN connector. Details can be
found in the accompanying electrical documentation.
3)
A shielded communication cable (e.g. Y(ST)Y..LG) must be
installed between the extension box and the heat pump
manager. It is connected between the -N17/J6 and -N1/
MH J29 connectors. Details can be found in the accompa-
nying electrical documentation.
HINWEIS
NOTE
When using three-phase current pumps, a power contactor
can be activated with the 230 V output signal from the exten-
sion box.
Sensor cables can be extended with 2 x 0.75 mm cables up to
50 m.
HINWEIS
NOTE
Further information on the wiring of the heat pump manager
is available in the electrical documentation.
CAUTION!
The communication cable is necessary for the function of air-
to-water heat pumps in outdoor installation. It must be
shielded and installed separately from the mains cable. It is
connected to N1-J25. For further information, see electrical
documentation.
