2.0 Enclosure Installation
The DS7400Xi control/communicator and the enclosure are shipped
together. The control, however, still needs to be installed into the
enclosure. Hardware for mounting the enclosure to a wall, and the
control to the enclosure is located in its own hardware pack.
2.1 Install the Enclosure
• Use the enclosure as a template and mark the top mounting holes
on the mounting surface.
• Pre-start the mounting screws for these two holes. Slide the en-
closure onto these mounting screws so that the screws move up
into the thinner section of the holes. Tighten the screws.
• Screw in the remaining two screws in either set of bottom mount-
ing holes.
• Knock out the desired wire entrances on the enclosure.
2.2 Install the Control/Communicator
CAUTION: The control is static sensitive. Make sure you touch
earth ground before handling the control. This will dis-
charge any static electricity in your body. Example:
Run the ground wire to the enclosure before handling
the control. Then keep holding the ground wire while
installing the control.
• Insert the three support posts into the control retainer holes as
shown in the diagram.
• Slide the top of the control into the retainer tabs (the slots under
the top frame).
• Once in the retainer tabs, the control will rest on the three support
posts.
• Secure the bottom of the enclosure by screwing the bottom three
holes through the support posts and through to the control retain-
er holes.
CAUTION: Once the control is installed, be sure to connect its
ground wire to the top hinge of the enclosure (the un-
painted tab).
