Installation
The Bus Coupler and all the Bus Terminals can be clipped, with a light press, onto a 35 mm mounting rail. A
locking mechanism prevents the individual housings from being pulled off again. For removal from the
mounting rail the orange colored tension strap releases the latching mechanism, allowing the housing to be
pulled off the rail without any force.

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.

Attention
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 electron-
ics in the Bus Terminals 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 un-
der power.
The right hand part of the Bus Coupler can be compared to a Bus Terminal. Eight connections at the top
enable the connection with solid or fine wires from 0.08 mm² to 2.5 mm². The connection is implemented with
the aid of a spring device. The spring-loaded terminal is opened with a screwdriver or rod, by exerting gentle
pressure in the opening above the terminal. The wire can be inserted into the terminal without any force. The
terminal closes automatically when the pressure is released, holding the wire safely and permanently.
