DANGER!
Risk to life through electrical current!
Contact with live components can cause serious inju-
ries.
Therefore:
-
When working on the device, all supply lines must
be without current.
-
Make sure that all electrical parts are without cur-
rent.
-
The applicable VDE and utility company regulations
as well as the respective regulations and guidelines
of the country of destinations must be complied
with.
-
The electrical connections must be inspected by a
responsible technician before establishing the con-
nection with the line supply.
-
An external separator (e.g. main switch) must be
envisaged for all electrical supply lines to the ma-
chine.
-
Only operate the heat pump within the implementa-
tion frequency (s. chapter 5.3 Type of electricity for
compressor) (in Germany 50 Hz).
CAUTION!
Interferences through electrical fields!
Supply lines (230 V) may interfere with sensor lines
(electrical low voltage).
Therefore:
-
Sensor and supply lines may not be routed in the
same cable conduit.
