Installation
Preparing the Enclosed Panel
Determine the location of the MPC-20 on the customer-supplied
flat or enclosed panel. The suitability of the enclosure is subject
to investigation by the local authority having jurisdiction at the
time of the installation.
Use the Installation Template measurements (included at the
end of the manual) as a guideline to cut a hole to the specified
dimensions. Drill holes where indicated on the template for the
mounting screws. Please read IMPORTANT note below:
IMPORTANT: When using the paper template
from the manual, please be aware that the drawing
is not represented to scale. The measurements
provided are accurate, and should be referred to
when preparing the placement of the unit.
Once the holes are cut, check to make sure that there is
adequate clearance for the edges of the MPC-20 housing to
mount flush against the outside surface of your panel.
Recommended torque for tightening the mounting screws is 7.5-
inch pounds. Although not required, only Blue polycarbonate
compatible thread lock should be used for the MPC-20 mounting
screws if thread lock is desired.
Insert the MPC-20 controller from the front side of the panel and
install the four mounting screws and lock washers. Ensure that
there is a good seal between the controller, the gasket (if used)
and the mounting panel. Plan the MPC-20 mounting for easy
wiring and access.
