5.3  Frame Ground 

 

Electronic circuits are constantly vulnerable to Electrostatic Discharge (ESD), 
which becomes worse in a continental climate area. Some I-7000 and M-7000 
modules feature a new design for the frame ground, which provides a path for 
bypassing ESD, allowing enhanced static protection (ESD) capabilities and 
ensures that the module is more reliable. 

 

Either of the following options will provide better protection for the module: 

 

1.

  If the module is DIN-Rail mounted, connect the DIN-Rail to the earth ground. 

This is because the DIN-Rail is in contact with the upper frame ground, as 
shown in the figure below. 

2.

  Alternatively, connect the lower frame ground terminal to a wire and connect 

the wire to the earth ground, as shown in the figure below. 

 

 

 

New DIN-Rail models are available that can easily be connected to the earth 
ground. Each rail is made of stainless steel, which is stronger than those made 
of aluminum. There is a screw at one end and a ring terminal is included, as 
shown in the figure below.
