Grounding is of particular importance for reliable, stable operation.  
Communication system characteristics may vary from system to system, 
depending on the system environment and grounding method used.  The 
PBDP-110 Profibus interface is provided with a “Shield GND” terminal on the 
bottom of the unit.  The “Shield GND” terminal is directly connected to the 
metallic housing of the DB9 connector, which should in turn be connected to 
the shield of the Profibus network cable through the Profibus connector.  To 
ground the network cable shield, therefore, connect a wire to the Shield GND 
terminal, and then connect the other end of the wire to an appropriate ground.  
For specific requirements regarding protective grounding and the Profibus 
network, refer to the Profibus Standard (EN 50 170, part 1). 
 
Please be sure to consider the following general points for making proper 
ground connections: 
 
Grounding method checkpoints 
1.  Make all ground connections such that no ground current flows through 

the case or heatsink of a connected drive. 

2.  Do not connect the PBDP-110 Shield GND terminal to a power ground or 

any other potential noise-producing ground connection (such as a drive’s 
“E” terminal). 

3.  Do not make connections to unstable grounds (paint-coated screw heads, 

grounds that are subjected to inductive noise, etc.)
