4.2 Installation distances
In order to be able to carry out the installation and subse-
quent maintenance work and to ensure sufcient ventilation,
the u-remote station must be installed while observing the
following minimum distances (see the following gures).
ATTENTION
Depending on how the station shielding is implemented,
the specied distances may have to be made larger, where
necessary.
The minimum permissible conductor bending radii must also
be observed. Earth terminals already installed can be ignored
when calculating the distance.

Example calculation for space requirements
The space requirements for the horizontal installation of a u-
remote station with n modules are calculated as follows:
D
W
Height: 120mm / 4.72"
+ 2 x 40mm / 1.57" (distances at top and bottom)
=200mm / 7.87"
Width: 8mm / 1.57" (end bracket)
+ 52mm / 2.05" (bus coupler)
+ nx11.5mm / 0.45" (nmodules)
+ 11.5mm / 0.45" (end plate and end bracket)
+ 2x20mm / 0.79" (distances to the sides)
=111.5 / 4.39" + nx11.5mm / 0.45"
