Minimum distances for ensuring installability

Note the dimensions shown in the following diagram for the design of the signal distribution board to ensure
safe latching and simple assembly / disassembly of the modules.

Observing the reaching area
A minimum reaching area of 92 mm is required for assembly / disassembly, in order to be able to
reach the mounting tabs with the fingers.
Adherence to the recommended minimum distances for ventilation (see section Installation position
[} 32]) ensures an adequate reaching area.
The signal distribution board must have a thickness of 1.6 mm and a minimum distance of 4 mm from the
mounting surface, in order to ensure latching of the modules on the board.
