6. Before installation
Read the installation manual carefully before installing homeCLU.
To be assessed before installation:
• Number of charge points
• Main inlet fuse size
• Preferred total charging current per phase
• Available charging current for each charging point
• Distribution network at inlet: TN netowrk or IT network (only Norway)
• Single-phase or three-phase charging
• Identify and label the phases on the power line in at the main inlet fuse
• Plan for a connection pattern. Find corresponding phase(s) between the inlet
fuse and the charge point(s). The charge points need unique addresses
› NB! The system will not work as intended if the phases do not correspond!
• Make sure the supply power is switched off during the entire installation
7. Phase connection pattern
Create a true phase rotation in the distributed circuits, one step per each charge point, as
shown in the installation diagrams. See separate document. By using a connection pattern
with true phase rotation, the system ensures an even load distribution among the phases.
This is important for single-phase charging, and for three-phase charging in cases where
single-phase vehicles are connected. PE-wiring is intentionally not shown in any of the
installation diagrams.
