Connection

WARNING

Risk of electric shock and damage of device!

Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or wiring of the bus terminals!

Connection 1:Fig.10: ED4078

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.
