10.3 Design rules
To help customers designing an application specific motherboard and for
correct and save function of the DEC Module 24/2 these rules can be
followed.
10.3.1 Ground
The ground (Gnd) pins of the DEC Module are internally connected (same
electrical potential). It is common practice to place a ground plane on the
motherboard and it is necessary to connect pins [5] and [15] with thick tracks
to the power supply voltage ground

If ground safety earth is available, connect the ground plane over some paral-
lel capacitors to the ground safety earth. Capacitors with 47 nF and 100 V are
suggested.
10.3.2 Layout
Motherboard layouts for DEC Module 24/2 should follow these rules:
–
Pin [4] +V
CC
: Use thick track to connect to the fuse.
–
Pins [5] and [15]: Use thick tracks to connect to supply voltage‘s ground
(Gnd).
–
The width and copper plating thickness of the power supply voltage and
motor winding traces depend on the maximum current expected in the
application. A minimum of 50 mil width at 35 μm thickness are recom-
mended.
