FLEX I/O AC Digital Input Modules
Electrical Safety Considerations
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.
• If 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.
WARNING: If you connect or disconnect wiring while the field-side 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 equipment is certified for use only within the surrounding air temperature
range of -20…55 °C (-4…131 °F). The equipment must not be used outside
of this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any
cleaning agents.
At the end of its life, this equipment should be collected separately from any
unsorted municipal waste.
