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.
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
