FLEX Ex Bus Isolator and Flexbus Connector 5
Publication 1797-5.13 - June 2010
Module Installation
Make certain that you only connect the FLEX Ex backplane connector to
other intrinsically-safe system modules to maintain the integrity of the
intrinsically-safe backplane.
ATTENTION
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.
These products are grounded through the DIN rail to the dedicated
intrinsic safety ground. Use zinc plated yellow-chromate steel DIN
rail to assure proper grounding. The use of other DIN rail materials
(such as aluminum or plastic) that can corrode, oxidize, or are poor
conductors, can result in improper or intermittent grounding.
ATTENTION
For proper operation, cycle power to the 1797-BIC module at the
same time power is cycled to the associated adapter.
