3.3 Electrical connection
Power is supplied to the user interface 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:
• 50 m at 0.50 mm
2
conductor cross-section
• 300 m at 1.50 mm
2
conductor cross-section.
▶ To avoid inductive interference: Make sure all low-voltage
cables are routed separately from mains voltage cables
(min. clearance 100 mm).
