MOUNTING AND WIRING

3.2 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 can not be made by pushing the housings
together on the mounting rail. When correctly assembled, no significant gap can be seen between
the attached housings.
WARNING!!
Insertion and removal of Bus Terminals is only permitted when switched off. The
electronics 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 under power.
