Mounting the Processor

The processor should be installed in an accessible, dry location where cabling can be accessed and
suitable ventilation is present. See the 972 Processor Mounting Template (P/N GT972) for hole
locations and clearance requirements.
It is absolutely necessary to mount the processor in a horizontal position as shown in Figure 2 so
that the unit's heat management system will work correctly. Normal motion of the vessel will not
cause a problem, but vertical or permanently angled mounting of the processor will cause
overheating of the unit's microprocessor.
A mounting plate is permanently mounted to the vessel, and the processor slides onto the plate and
is secured with two screws at the front edge. Vertical clearance of at least 7-1/2 inches is required for
installation and removal of the processor. Be sure to provide ample clearance around the processor to
make it easy to install and remove cables at the rear of the unit.
