Electrical connection

Power is supplied to the solar controller via the BUS cable.
The wires are insensitive to polarity.
If the maximum total length of the BUS interfaces between all
BUS nodes is exceeded or the BUS system has a ring structure,
commissioning of the system is not possible.
Maximum total length of BUS interfaces:
2
• 100 m at 0.50 mm conductor cross-section
2
• 300 m at 1.50 mm conductor cross-section.
▶ If several BUS nodes are installed, maintain a minimum
clearance of 100 mm between the individual BUS nodes.
▶ If several BUS nodes are installed, connect the BUS nodes
in series or in a star pattern.

▶ To avoid inductive interference: Make sure all low-voltage
cables are routed separately from mains voltage cables
(min. clearance 100 mm).
▶ In the case of external inductive interferences (e.g. from
photovoltaic systems), use shielded cables (e.g. LIYCY)
and earth the shield on one side. The shield should be
connected to the building's earthing system, e.g. to a free
earth conductor terminal or water pipes, and not to the
grounded terminal in the module.
▶ Make a BUS interface to the solar module.
