ATTENTION: Read this document and the documents listed in the Additional Resources section about installation, configuration, and operation of this 

equipment before you install, configure, operate, or maintain this product. Users are required to familiarize themselves with installation and wiring 

instructions in addition to requirements of all applicable codes, laws, and standards.

Installation, adjustments, putting into service, use, assembly, disassembly, and maintenance are required to be carried out by suitably trained 

personnel in accordance with applicable code of practice. In case of malfunction or damage, no attempts at repair should be made. The module 

should be returned to the manufacturer for repair. Do not dismantle the module.

Description:

ATTENTION: 

• This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated steel DIN rail to assure proper grounding. The 

use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or 

intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to 

ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for more information.

• Do not remove or replace an Adapter Module while power is applied. Interruption of the backplane can result in unintentional operation or 

machine motion.

• Do not remove or replace a terminal base while power is applied. Interruption of the backplane cab result in unintentional operation or 

machine motion.

• If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

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: 

• 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.
