ATTENTION:
This equipment is certified for use only within the surrounding air
temperature range of 0…55 °C (32…131 °F). The equipment must not be used
outside of this range.
ATTENTION:
Use only a soft dry anti-static cloth to wipe down equipment. Do
not use any cleaning agents.
ATTENTION:
This product is grounded through the DIN rail to chassis ground.
Use zinc plated chromate-passivated 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. Be sure to ground the DIN rail
properly. Refer to Industrial Automation Wiring and Grounding Guidelines,
Rockwell Automation publication
1770-4.1
, for more information.
WARNING:
When you insert or remove the module while backplane power is
on, an electric 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.
Repeated electric 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.
