Installation on mounting rails

Risk of injury through electric shock and damage to the device!
Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or
wiring of the Bus Terminals.
Mounting
The Bus Couplers and Bus Terminals are attached to commercially available 35 mm mounting rails (DIN rail
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 compo-
nents 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 tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the mounting rails with a height of 7.5 mm under the terminals
and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
Disassembly
Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:
