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.

The bus isolator modules, 1797-BIC and 1797-CEC, let you configure FLEX Ex modules and FLEX I/O modules on the DIN rail when attached to the same adapter and grouped together on appropriate sides of the bus isolator module. This highly flexible, cost-effective solution combines intrinsically safe and nonintrinsically safe systems.

Intermixed systems can be configured for use in the:

• safe area much like traditional IS and I/O systems.

• hazardous and safe control equipment where the distance of physical separation is short.

• FLEX Ex I/O with communication adapters that are not intrinsically safe.

oduct Features

• Provides an IS-compatible mechanism to separate two sections of the backplane allowing IS and non-IS field-device wiring to the same I/O group.

• Converts hazardous power to IS-safe power to run one side of the bus receiver/transmitter circuitry and IS-safe FLEX Ex backplane power

to slave side modules.

• Allows up to eight FLEX Ex modules may be attached to the slave side.
