Prevent Electrostatic Discharge
Remove Power
ATTENTION
Electrostatic discharge can damage integrated circuits or semiconductors
if you touch bus connector pins. Follow these guidelines when you handle
the module:
– Touch a grounded object to discharge static potential.
– Wear an approved wrist-strap grounding device.
– Do not touch the bus connector or connector pins.
– Do not touch circuit components inside the module.
– If available, use a static-safe work station.
– When not in use, keep the module in its static-shield box.
ATTENTION
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
– sending an erroneous signal to your system’s field devices, causing
unintended machine motion.
– causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
