10.3 Design rules
To help customers designing an application specific motherboard and for
correct and save function of the DEC Module 50/5 these rules should 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 mo-
therboard and it is necessary to connect pins [9], [10], [14], [16] and [24] with
thick tracks to the power supply voltage ground

If ground safety earth is mandatory, connect the ground plane over several
parallel capacitors to the ground safety earth. Ceramic chip capacitors with
47 nF and 100 V are suggested.
10.3.2 Layout
Motherboard layouts for DEC Module 50/5 should follow these rules:
–
Pins [7] and [8] +V
CC
: Use thick track to connect to the fuse.
–
Pins [9], [10], [14], [16] and [24]: 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 75 mil width at 70 μm thickness is recommen-
ded.
