WARNING

Risk of injury through electric shock and damage to the device!

Bring the bus terminal system into a safe, de-energized state before beginning to mount, disassemble, or wire the bus terminals!

Notice

Cable lengths > 30 m

For cable lengths > 30 m, suitable overvoltage protection (surge protection) must be provided (e g. EL9540-0010) if corresponding interference could affect the signal cable.
