FlexLogix Controller System
Publication 1794-IN002F-EN-P - October 2002
Take these precautions to guard against ESD damage:
Removal and Insertion Under Power
While backplane power is applied and the system is operating, you can only install or remove
FLEX I/O modules. The FlexLogix controller, the extended-local I/O adapter, the
communication daughtercards, and the I/O terminal bases are not removable or insertable
under power.
Repeated electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that can
affect module operation.
ATTENTION
!
Preventing Electrostatic Discharge
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.
·
If available, use a static-safe workstation.
·
When not in use, store the equipment in appropriate
static-safe packaging.
WARNING
!
When 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.
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
(e.g. aluminum, plastic, etc.) that can corrode, oxidize, or are
poor conductors, can result in improper or intermittent
grounding.
