Assembling parts
Assemble all parts of the UMC800 along with tools required to mount the UMC800 hardware. You should
have these tools on hand:
• Tool box that includes a center punch and a standard complement of flat blade and Phillips head
screwdrivers as well as box-end and open-end wrenches.
• A drill tap and drill with number 9 drill bit for drilling clearance holes as applicable.
• Tools for measuring and marking location of clearance holes and cutout on panel as well as cutting a
hole in the panel.
Mounting the Controller
Mounting controller enclosure on a panel
The controller enclosure is made to be surface mounted within an enclosure. The controller can be mounted
so that the power supply is at the righthand side, or the controller can be rotated 90 degrees so that the
power supply is at the top. For either mounting, there must be sufficient space allowed for routing the
external wiring.
Four holes at the back of the enclosure are provided for surface mounting with screws. Use the steps in the
table below to mount the controller enclosure on a panel.
Step Action
1 Layout mounting hole patterns on panel according to dimensions shown in Figure 8. Or,
position controller enclosure on panel and use enclosure as a template.
NOTE: Rotate the mounting dimensions 90 degrees to mount the enclosure sideways with
the power supply at the top.
2 Drill and tap mounting holes for 1/4-20 (or M6) machine screws (supplied by user).
3 Position enclosure on panel so holes in enclosure align with holes in panel. Secure enclosure
to panel with 1/4-20 (or M6) machine screws using external tooth washers.
