Nibe AMB 30, Installer Manual

Page: 22 / 52

General
All electrical equipment, except the ambient temperat-
ure sensor, circulation pumps, reversing valves and ex-
ternal communication is already connected at the
factory.
The cables for heavy current and the signal cables
should be routed from the side at the folded part of
the side panel on the left-hand side of AMB 30. Power
supply is routed through the cable grommet UB1,
power supply for the circulation pumps and reversing
valves through UB2 toUB4, communication cables
through UB5 to UB7 and signal cables through the re-
maining cable grommets.
႑
Connection of AMB 30 may not occur without the
approval of the electricity supplier and must be su-
pervised by an authorised electrician.
႑
Disconnect the heat pump and AMB 30 before insu-
lation testing the house wiring.
႑
If the building is equipped with an earth-fault
breaker, each AMB 30 should be equipped with a
separate one.
႑ If a miniature circuit breaker is used it should have
motor characteristic “C”. For MCB size see "Technical
Specifications".
႑
For the air collector module electrical wiring diagram,
see page 45.
႑
Communication and sensor cables to external con-
nections must not be laid close to high current cables.
႑
The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up
to 50 m, for example EKKX or LiYY or equivalent.
႑ When cable routing in AMB 30, cable grommets must
be used according to the table below.
