16AI, 8RO, 8DO, and Gateway boards not supplied
with an enclosure are supplied with a snap-track for easy

removed from the track before the track is mounted. The
snap-track is mounted using the 0.1875” mounting slots.
Figure 3-10 shows this installation procedure.

The Gateway is typically mounted in the same area as
the site controller, near the controller’s 16AI, 8RO, and
other RS485 Network peripherals. The Gateway is
designed to fit into a standard 3" snap track (supplied with
the board) or may be mounted in a panel or on stand-offs.
Follow the dimensions in Figure 3-12 for panel mounting.
