Prevent Electrostatic Discharge

Publication 1746 -IN002A-US-P

Static discharges may cause permanent damage to the
module. Follow these guidelines when you ha ndle the
module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist strap grounding device.

• Handle module by plastic case only. Avoid contact
between module circuits and any surface which can
hold an electrostatic charge.

• If available, use a static-safe work station.
