Installation distances

In order to be able to carry out the installation and subse-
quent maintenance work and to ensure sufficient ventilation,
the u-control station must be installed while observing the
following minimum distances (see the following figures).
Depending on how the station shielding is implemented,
the specified 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.

Calculation of space requirements
The space requirements for a u-control station with n mod-
ules (horizontal installation) is calculated as follows:
W
D
20 mm
Height: 120 mm (4.72")
+ 2
0.79"
= 200 mm (7.87")
Width: 8 mm (1.57" )
+ 52 mm (2.05")
+ n
+ 11.5 mm (0.45")
+ 2
= 111.5 mm (4.39") + n
For vertical installation please interchange height and
width. When calculating the width, 12.5 mm / 0.49"
must be added for the end bracket MEW 35/1 (Order No.
1805610000).
