Danger
Incorrectly executed electrical installations can lead to injury through the
transmission of dangerous body currents and result in equipment
damage.
Carry out the power supply connection and all earthing measures (i.e
RCD circuit) in accordance with IEC 364, the requirements of your local
power supply utility, VDE or local and national regulations.
Main isolator requirements (if necessary)
If a main isolator is set, it must isolate
the power circuit with at least 3 mm
contact separation.
If no main isolator is set, all non-
earthed cables must be isolated by
the upstream cable protection switch
with at least 3 mm contact separation.
General information regarding the power supply
The power supply is separated into 3
areas:
&
Control unit feed (electronics)
&
Instantaneous heating water heater
feed (main power circuit)
&
Heat pump compressor feed (main
power circuit)
Subject to heat pump, the equipment
is connected to a 400 V three phase
AC or 230 V single phase AC supply.
