1.2 Regulations and safety notes
During commissioning, observe the respective country-
specific safety regulations and the applicable VDE safety
regulations, particularly VDE 0100 as well as the technical
connection requirements of the utility companies (EVU)
and supply network operators!
The extension box should only be operated in dry rooms
with temperatures ranging between 0 °C and 35 °C. En-
sure that no condensation forms on the device.
All sensor connecting cables with a conductor cross-sec-
tion of 0.75 mm² can be extended to a maximum of 40 m.
Sensor cables should not be installed next to power cables.
To ensure that the frost protection function of the heat
pump works properly, the heat pump controller must re-
main connected to the power supply and the flow must be
maintained through the heat pump at all times.
The switching contacts of the output relay are interfer-
ence-suppressed. Therefore, depending on the internal re-
sistance of the measuring instrument, a voltage can also be
measured when the contacts are open. However, this will
be much lower than the line voltage.
At the adapter boards -N17/LV as well as the pins -N1/J9 ..
J14 and J29 and -N17/J6 and J9, an extra-low voltage is
present. If, due to a wiring error, the line voltage is mistak-
enly connected to these terminals, the heat pump manager
will be destroyed.
