2.1 Mounting the VT-MODEM-4
The VT-MODEM-4 snaps onto standard DIN rail (DIN EN 50022) or is mounted to a flat panel using #6 or #8
screws. See the image below. The modem can be installed in any orientation, directly adjacent to other DIN rail
components or in any convenient location within the enclosure. The modem should be installed within 6 feet of the
device it will be connected to.
[7.42cm]
For DIN rail mounting, hook the top, rear of the modem onto the top edge of the DIN rail. Using a small flathead
screwdriver, pull down on the spring-loaded tab on the bottom of the modem and push the modem back against the
rail. Reverse these steps to remove the modem. See the image below.
