Identifies information about practices or circumstances that can cause an explosion in a hazardous environment, which may lead to personal injury or death, property damage, or economic loss.

Installation Instructions

When you insert or remove the module while backplane 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.

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.

FLEX I/O systems are grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate 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.

Mount the Terminal Base Unit on a DIN Rail

During mounting of all devices, be sure that all debris (such as metal chips or wire strands) is kept from falling into the module. Debris that falls into the module could cause damage upon application of power.

1. Remove the cover plug (if used) in the male connector of the unit to which

you are connecting this terminal base unit.

2. Check to make sure the 16 pins in the male connector on the adjacent

device are straight and in line so that the mating female connector on this terminal base unit will mate correctly.

3. Make certain the female connector (B) is fully retracted.

4. Position the terminal base unit on the 35 x 7.5 DIN rail (A) (A-B pt no.

199-DR1).

Do not force the terminal base into the adjacent base/adapter. Forcing the units together can bend or break the hook and allow the units to separate and break communication over the backplane.

6. Refer to the installation instructions for specific wiring information for the

module you are installing in this terminal base.

7. Repeat the above steps to install the next terminal base.

When using FLEX I/O modules in a high-vibration installation, especially when mounting the DIN rail vertically, use DIN-rail locks (A-B part number 1492-EA35) to prevent accidental separation of the terminal block units.

Wire Connections for the Terminal Base Units

5. Rotate the terminal base onto the DIN rail with the top of the rail hooked under the lip on the rear of the terminal base. Use caution to make

sure that the female flexbus connector does not strike any of the pins in the mating connector.
