3-4 Installation and Wiring
Prevent Electrostatic Discharge
Remove Power
Reducing Noise
We recommend installing this module in an industrial enclosure to
reduce the effects of electrical interference. Group your modules to
minimize adverse effects from radiated electrical noise and heat.
ATTENTION
!
Electrostatic discharge can damage integrated circuits
or semiconductors if you touch the 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 it is 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 and may
lead to premature failure.
