Up to 64 Bus Terminals can be attached to the Bus Coupler on the right hand side. When plugging the
components together, be sure to assemble the housings with groove and tongue against each other. A
properly working connection cannot be made by pushing the housings together on the mounting rail. When
correctly assembled, no significant gap can be seen between the attached housings.

Bus Terminals should only be pulled or plugged in switched-off state.
Insertion and removal of Bus Terminals is only permitted when switched off. The electronics in the Bus Ter-
minals and in the Bus Coupler are protected to a large measure against damage, but incorrect function and
damage cannot be ruled out if they are plugged in under power.
