ATTENTION Environment and Enclosure
This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR Publication 11. Without
appropriate precautions, there may be potential difficulties
ensuring electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding
specific enclosure type ratings that are required to comply with
certain product safety certifications.

Frequently Answers and Questions
How many ControlNet Ex nodes can be connected with this adapter?
A maximum of 48 ControlNet Ex nodes can be connected together by 250 meters of coax cable and 48 taps. However, the distance increases to 1000 meters when you only use 2 taps.
What are the required environmental conditions for installing this adapter?
The adapter must be mounted within an enclosure that is suitably designed for the specific environmental conditions present and appropriately designed to prevent personal injury resulting from accessibility to live parts.
What is the purpose of the Output Enable bit in the FLEX Ex output module?
The Output Enable bit allows the system to initialize the activity of a module's outputs. Before the Output Enable bit is transitioned to 1, module outputs remain off. Once the bit is transitioned to 1, subsequent transitions of the Output Enable bit by any source will cause the output module to apply the local module fault state.
