Frame Ground - ICP DAS USA tM-TH8 User Manual

A.3 Frame Ground
Electronic circuits are constantly vulnerable to ESD which
become worse in a continental climate area. The tM
modules feature a new design for the frame ground. The
frame ground provides a path for bypassing ESD, which
provides enhanced static protection (ESD) abilities and
ensures the module is more reliable.
Connect the frame ground terminal to a wire/DIN rail and
connect the wire/DIN rail to the earth ground will provide
a better protection for the module.
New DIN rail models are available that can easily be
connected to the earth ground. Each 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. Refer to Section 1.13.1 for
more information about the new DIN rail models.
