Note

5 V DC at the power contacts

During configuration of the Bus Terminal block, please note that the power contacts of the EL2124 carry a voltage of 5 VDC (provided e.g. by an EL9505 power supply terminal).
If 24 V terminals are to operate in the terminal block simultaneously, measures must be implemented for electrical isolation (e.g. through the EL9190 power feed terminal or the EL9080 separation terminal).
