You can attach the VRF Smart Gateway to a 1-1/8 in. (35 mm) DIN rail or a flat vertical surface. Mounting the unit on a ceiling or in a way that positions the front of the unit facing down is not recommended.
Although the unit has two mounting clips, only the bottom clip snaps inward. The top clip is permanently locked in the outward position, and it can be used as an additional hole for screwing the unit into place. If not utilized for DIN rail or surface mounting, you can remove the top and bottom clips from the unit.
DIN Rail Mounting
To mount the unit on a DIN rail:
- Securely mount a 3 in. (7.5 cm) or longer section of 1-1/8 in. (35 mm) DIN rail in the required space.
- On the unit, pull the bottom mounting clip
outward to the extended position. Figure 1. Positioning the Unit on a DIN Rail
- Hang the unit on the DIN rail by the hooks at the top of the DIN rail channel (on the back of the bracket), and position the unit snugly against the DIN rail.
- Push the bottom-mounting clip inward to secure the unit on the DIN rail.
You can mount the unit using the holes in the DIN rail clips. This orientation helps accommodate on-site constraints. Screw hole locations are shown in Figure 3.
The screw types needed to mount the unit depend upon the surface to which the unit is mounted. The screw holes on the VRF Smart Gateway can accommodate M3.5 and #6 screws.
For information on location considerations for maximizing signal strength, see Mounting.
To mount the unit on a flat surface (such as a wall):
- Pull the bottom mounting clip outward to the extended position.
- Mark mounting hole locations on the wall
using the dimensions shown in the following figure; or hold the bracket against the
wall and mark the hole locations through the mounting clips. Note: The position of the location holes depends on whether the bracket is mounted horizontally or vertically.Figure 3. Mounting Holes, Flat Mounting, DIN Rail Screws, in. (mm)
Note: The screw holes on the VRF Smart Gateway can accommodate M3.5 and #6 screws.
- Drill holes in the wall based on the locations marked in the preceding step, and insert wall anchors for each hole (if necessary).
Hold the unit in place, insert the screws through the mounting clips and into the screw holes, and then carefully tighten all screws.Important: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting clips or bracket.
