Mount on a Panel or Wall If mounting this adapter to a panel or wall, refer to publication 1794-IN135, Panel Mounting Kit, Cat. No. 1794-NM1/B. Mount or Replace the Adapter on an Existing System 1.
Page 11 FLEX I/O EtherNet/IP Adapters Before installing the new adapter, notice the notch on the right rear of the adapter. This notch accepts the hook on the terminal base unit. The notch is open at the bottom. The hook and adjacent connection point keep the terminal base and the adapter tight together, reducing the possibility of a break in communication over the backplane.
Page 12 FLEX I/O EtherNet/IP Adapters Connect Wiring WARNING: If you connect or disconnect the communication cable with power applied to the adapter 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.
Page 13 FLEX I/O EtherNet/IP Adapters IMPORTANT We recommend connecting the module to the network via a 100 MB full- duplex switch, which will reduce network collisions and lost packets, and increase bandwidth.
