ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Rockwell Automation Publication
8000-4.5.2, Guarding Against Electrostatic Discharge,
or any other applicable ESD protection handbook.
Electrostatic discharge generated by static electricity can damage the
complementary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
•
Wear a wrist-type grounding strap that is grounded to the chassis.
•
Attach the wrist strap before removing the new circuit board from
the conductive packet.
•
Remove boards from the drive and immediately insert them into
their conductive packets.
