1734 POINT I/O EtherNet/IP Adapter 13

Publication 1734-IN042B-EN-P - October 2013

Replace The Adapter

Use these procedures to install a replacement adapter to an existing system.

1. Disconnect the Ethernet connector(s) from the adapter.

2. Pull up on the Removable Terminal Block (RTB) handle to remove the terminal

block.

3. Remove the adjacent module from its base.

4. Use a small bladed screwdriver to rotate the DIN rail locking screw to a vertical

position. This releases the locking mechanism.

5. Lift straight up to remove.

6. Slide the safety end cap up to remove it, which exposes the backplane and power

connections.

7. Position the replacement adapter vertically above the DIN rail, making certain

the DIN rail lock is in the horizontal position.

8. Slide the adapter down, allowing the interlocking side pieces to engage the

adjacent module.

WARNING: 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.

Repeated electrical 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.

WARNING: When you connect or disconnect the Removable Terminal Block

(RTB) with field side power applied, 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: If you connect or disconnect the communications cable with

power applied to this module or any device on the network, 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.
