5.0 Mounting
•
The backs of both the IFD-5 Digital Interface Module and IFA-5 Analog Output Module
have attachments for easy DIN rail mounting. To attach the modules to a DIN rail pull the
orange tab at the bottom of the module out, slip the module onto the DIN rail and push the
tab back in to secure the module to the rail. A short piece of DIN rail is provided for
mounting the Module to solid surfaces.
•
It is recommended that the modules be mounted in a cabinet or NEMA enclosure rated for
area of use. See mounting examples in section 5.1
