6.5 Power supply 230V heat pump version - Connection to three phase grid
Connection possibilities, 230V~3 three phase grids with:
1. One common feeding cable to supply both compressor and immersion heater. This is default from factory. (Inbuilt auxiliary heater
power = 2/4/6 kW.)
or
2. Two separate feeding cables to supply compressor and immersion heater separately. (Inbuilt auxiliary heater power = 2/4/6 kW.)
This alternative will reduce required fuse size and required inlet cable area but requires that the jumpers fitted in the terminals are re-
moved. (See connection picture). To remove jumpers, use a flat screw driver and remove the 2 red jumpers fitted on the terminal block
before connecting heat pump to the grid.
