Attachingtheendbracket
When installing the u-remote products, make
sure that you listen for the double click:
1. When snapping onto the DIN rail
2. When pushing together with the neighbour-
ing module.
The modules are in the correct position and
the connection is made only when both snap-
ping noises are heard.
ATTENTION
Improper installation may prevent
earthing!
The earthing of the modules and couplers is
only ensured if the FE spring at the bottom is
in contact with the DIN rail.
▶ During installation, make sure that both
release levers on the bus coupler and all
release levers on the modules are closed
before snapping onto the DIN rail.

▶ Place the field bus coupler (module side to the right) on
the DIN rail so that it audibly clicks into place.
