The block I/O module has an equipment grounding stud on the lower left side of
the module. Connect this grounding stud to your equipment ground. Torque the
nut to 15 in-lbs maximum when connecting to your equipment ground.
ATTENTION: Do not overtighten the nut on the grounding stud
when connecting the wire. Damage to the module could result.
Refer to “Industrial Automation Wiring and Grounding Guidelines” (1770-4.1)
for further information.
