Control Panel Cooling
An assembled Control Panel can be operated from a tabletop, or it can be installed into a
cutout.
The Local Aux Stripe can be connected to the Control Panel support structure at a 45
degree angle, or it can be mounted separately in its own backsplash cutout.
The following diagrams show some standard Control Panel assemblies. It is also possible to
create different Control Panel assemblies (for example, a 2-M/E 35), since the parts are
interchangeable. Specific information for non-standard configurations is not included in
this document.
Control Panel Cooling
The Kayenne Control Panel is externally powered and does not have internal cooling fans.
Electronics in the panel are convection cooled and require free air movement. Do not install
the panel into a sealed space.
Truck and High Vibration Environment Considerations
The Kayenne Control Panel has several bolt and screw tightened components. In high
vibration environments these attachments could loosen over time. Loctite Blue 242 or
equivalent thread locking compound is recommended for these environments. This
compound is designed to lock threaded components together during assembly, but
permits them to be loosened if necessary later using hand tools.
During Control Panel assembly, apply a drop of the locking compound to the ends of the
threads of the support beam bolts, to the screws connecting the cutout lip brackets to the
support beams, and to the bolts attaching the trays to the support beams. Make sure the
locking compound is present where the thread interfaces to each bolt or beam.
CAUTION: If the panel is mounted in a counter-top, do not enclose the
lower portion of the cutout. Leave the bottom open to
allow passive air movement.
