WARNING

Risk of electric shock!

Bring the Bus Terminal system into a safe, de-energized state before starting installation, removal or wiring of the terminal modules!

Notice

Risk of device damage!

Note that the use of potential separation terminals (e.g. EL9080) is necessary when planning the Bus Terminal system with different potentials on the power contacts (e.g., 24 VDC and 230 VAC)!
