Mounting rail installation
Installation
The Bus Couplers and Bus Terminals are attached to commercially available 35 mm mounting rails
(according to EN 60715) by applying slight pressure:
1. First attach the Fieldbus Coupler to the mounting rail.
2. The Bus Terminals are now attached on the right-hand side of the fieldbus Coupler. Join the
components with slot and key and push the terminals against the mounting rail, until the lock
clicks onto the mounting rail.
If the terminals are clipped onto the mounting rail first and then pushed together without slot
and key, the connection will not be operational! When correctly assembled, no significant gap
should be visible between the housings.
3. During the installation of the Bus Terminals, the locking mechanism of the terminals must not
come into conflict with the fixing bolts of the mounting rail.
