Motor Control Module (MCM)
for the
4848 Reactor Controller
Installation Instructions
1. Unplug the power cord of the 4848 controller. Re-
move the (2) screws located on the top/front cover at
the rear corners of the controller. Gently lift the cover
forward, which is hinged at the bottom, taking care
not to apply tension on any internal wiring.
2. If applicable, remove and discard the black hole plug
on the sloped front panel above the "RPM" text. This
can be done by pinching the clasps on the back of the
plug from the inside of the front plate.
3. Insert the MCM (2084E) through the panel cutout,
from outside in, making sure the rubber gasket is
on the outside of the controller front panel. (If wires
are preinstalled, remove the terminal connector by
releasing the tabs on the sides of the module and
gently pulling the terminal connector off. Reference
photos below.) Slide the white mounting bracket
onto the module with the mounting screws pointing
towards the front panel. Slide the mounting bracket
forward until it touches the controller panel. The
clasps on the mounting bracket should align with the
groves on the module. Gently tighten the screws un-
til the module is held into place. (If removed, reattach
the terminal connector.)
