WARNING: When you connect or disconnect the Power or Alarm Removable Terminal Blocks (RTBs) with field side power
applied, 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: If you connect or disconnect communication cables with power applied to this module or any device on the network,
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: Use supply wires suitable for 30 °C (86 °F) above surrounding ambient.
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.
WARNING: Do not use the USB-mini console port in hazardous locations.
