6-1-4 Installing the EtherNet/IP Coupler Unit
3 Press the EtherNet/IP Coupler Unit firmly against the DIN Track until you hear the DIN Track
mounting hook lock into place.
After you mount the EtherNet/IP Coupler Unit, check to be sure that it is securely mounted on
the DIN Track.
Precautions for Correct Use
The EtherNet/IP Coupler Unit may not be mounted properly to the DIN Track if the protrusions
on the left back of the EtherNet/IP Coupler Unit interfere with the screw that fixes the DIN Track
as shown in the following figure.
When you mount the EtherNet/IP Coupler Unit to the DIN Track, avoid interference of the pro-
trusions on the left back of the EtherNet/IP Coupler Unit with the screw on the DIN Track. (This
applies to Ethernet/IP Coupler Units with lot numbers through December 2014.)
It is not normally necessary to unlock the DIN Track mounting hooks when you mount the Eth-
erNet/IP Coupler Unit. However, if you mount the EtherNet/IP Coupler Unit on a DIN Track that
is not one of the recommended DIN Tracks, the DIN Track mounting hooks may not lock prop-
erly. If that happens, unlock the DIN Track mounting hooks at the start of the procedure, mount
the Unit to the DIN Track, and then lock the DIN Track mounting hooks.
