Mounting and cabling
EL675216 Version: 2.1
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 recommended mounting rails under the terminals and cou-
plers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!
Mounting
• Fit the mounting rail to the planned assembly location.
and press (1) the terminal module against the mounting rail until it latches in place on the mounting
rail (2).
• Attach the cables.
Demounting
• Remove all the cables. Thanks to the KM/EM connector, it is not necessary to remove all the cables
separately for this, but for each KM/EM connector simply undo 2 screws so that you can pull them off
(fixed wiring)!
• Lever the unlatching hook on the left-hand side of the terminal module upwards with a screwdriver (3).
As you do this
◦ an internal mechanism pulls the two latching lugs (3a) from the top hat rail back into the terminal
module,
◦ the unlatching hook moves forwards (3b) and engages
