Frame Ground
Electronic circuits are constantly vulnerable to Electro-Static Discharge (ESD),
which become worse in a continental climate area. PET-7000/ET-7000 series
modules feature a new design for the frame ground, which provides a path for
bypassing ESD, allowing enhanced static protection (ESD) capability and ensures
that the module is more reliable.
The following options will provide a better protection for the module:
The PET-7000/ET-7000 controller has a metallic board attached to the back of the
plastic basket as shown in the figure below, point 1.
When mounted to the DIN rail, connect the DIN rail to the earth ground because the
DIN rail is in contact with the upper frame ground as shown in the figure below,
point 2.
