Prevent Electrostatic Discharge
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:
 Touch a grounded object to discharge potential static.
 Wear an approved grounding wriststrap.
 Do not touch connectors or pins on component boards.
 Do not touch circuit components inside the equipment.
 Use a static-safe workstation, if available.
 Store the equipment in appropriate static-safe packaging when not in
use.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
WARNING
If you insert or remove the module while backplane power is on, an electrical
arc can occur. This could cause an explosion in hazardous location
installations.

Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING
When you connect or disconnect the battery an electrical arc can occur. This
could cause an explosion in hazardous location installations. Be sure that the
area is nonhazardous before proceeding.

WARNING
If you connect or disconnect the serial cable with power applied to this module
or the serial device on the other end of the cable, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
