3.7 Electrical connections
A general description of the needed electrical connections is given in this section. The
actual connections should be made according to the wiring diagrams delivered with the
heat pump.
Electrical installation is to be carried out by authorized and trained
personnel only.
Before performing any work on electrical components, make sure that
there is no voltage present.
Do not connect devices that draw over 2 A of current directly to the
controller. Use a contactor instead.
