The electrical connection is made according to the wiring diagram in
chapter 5.4.
The circuit protection in the distributor (meter cabinet) must be made
with a 3-pole power circuit breaker (C-characteristics) according to
the output ratings of the heat pump. The potential equalization is to
be connected at the M6 or M8 connecting screw marked for this
purpose.
