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.)
