Mounting The Control Head - NorthStar 972 Installation Manual

SECTION TWO: Installing and wiring the 972

Mounting the Control Head

Choosing the best mounting location
Choose the mounting locations carefully before you drill or cut. The control head should be
mounted so that the operator can easily use the controls and clearly see the display screen. Be sure
to leave a direct path for all of the cables. The display screen is high-contrast and anti-reflective, and
is viewable in direct sunlight, but for best results, install the 972 out of direct sunlight. The chosen
location should have minimal glare from windows or bright objects.
Leave sufficient clearance space behind the control head for all of the cables and connectors. Good
ventilation is required behind the mounting panel. Poor ventilation may cause the 972 to overheat,
which, in turn, will cause the screen brightness to dim. For overall width and height requirements,
see the Northstar 972 Mounting Template (P/N GT15), which you can use to drill the mounting holes
and cut the mounting panel in the exact recommended locations.
Use the supplied template to cut the hole for the control head, and use the supplied gasket between
the control head and the instrument panel to help seal against water penetration. The use of
anti-seize compound on the flush-mount studs and nuts is recommended.
The parts kit contains 12 threaded studs, flat washers, lock washers, and hex nuts for flush
mounting.

CAUTION! Proper installation of the Northstar 972 is critical to accurately receive
and effectively use GPS/WAAS signals under a wide variety of weather
conditions.
Keep the following safe compass distance from the 972 head and
processor: 1.0m standard, 0.8m steering.
CAUTION! Be sure to mount the 972 on a flat surface. Mounting on a curved
surface can result in water leaks. Do not overtighten the mounting
screws; you may damage the case and compromise its waterproof
seal. This type of physical damage will void the warranty.
