Calculation of space requirements
The space requirements for a u-remote station with n mod-
ules (horizontal installation) is calculated as follows:

Installation sequence
A u-remote station may only be installed in this sequence
(starting from the left/bottom):
– End bracket
– Bus coupler
– Up to 64 active modules
– End plate and end bracket
If the station has already been congured, please proceed to
the corresponding installation drawing. If you are conguring
the station yourself, please observe the following instruc-
tions:
– Observe the maximum current carrying capacity (see sec-
tion 4.5)!
– Furthermore, the modules may be arranged in any
sequence. In order to configure the station as clearly as
possible, we recommend arranging the modules accord-
ing to their function.
Arrangement of safe power-feed modules
A safe power-feed module (PF-O-xDI-SIL) can be positioned
anywhere in the u-remote-station. All of the following output
modules up to the next PF-O module will be safely discon-
nected (safety segment). Multiple safe power-feed modules/
safety segments can be set up in a single station.
When using u-remote safe power-feed mod-
ules, please also observe the Modules for
Functional Safety Manual.
The manual is available to download from the
Weidmüller website.
Preparation and the required tool
The DIN rail must already be installed. To mechanically install
the u-remote station, you will need a 3-mm screwdriver.
▶ Lay out the modules in the intended sequence.
▶ Check whether the DIN rail feet can be moved on both
end brackets. If necessary, loosen the mounting screw
until the DIN rail feet can be moved freely.
▶ If not done yet, fit an earth terminal to the DIN rail.
