The total width in practical cases is composed of the width of the Bus Coupler with the KL9010 Bus End
Terminal and the width of the Bus Terminals in use. Depending on function, the Bus Terminals are 12 mm or
24 mm wide. The front wiring increases the total height of 68 mm by about 5 mm to 10 mm, depending on
the wire thickness.

Mounting
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.
