Choosing A System Location - NorthStar GM1708 961X Installation Manual

Choosing a system location

Mounting the
control head
961 INSTALLATION MANUAL Revision A
The 961 consists of two major parts—a processor and a control head. The
961 supports two fully functional control heads (the second head is
optional). The 961 system comprises the processor and control head, GPS
receiver, optional differential receiver, controls, and the specially-coated
display screen.
You can either yoke- or flush-mount the control head: Use the
yoke-mount kit as a framework for holding the control head, or
flush-mount the control head directly onto a flat surface of your choice.
Using the Northstar-supplied yoke mounting kit usually provides a
quicker and less expensive installation than a flush-mount installation.
Regardless of the type of mount, here are a few helpful hints about where
to mount the control head. Choose the mounting location care-
fully—before any drilling or cutting takes place. Choose a location that:
is convenient, accessible, and within comfortable reach
•
gives you easy access to the function keys
•
is where you can clearly see the display screen from your normal
•
vantage point when navigating
for best display contrast, is viewed from below, looking up at the
•
display screen
provides a reasonably direct path for running the required electrical
•
cables
has minimal glare from windows or other bright objects (even
•
though the unit has a high-contrast, anti-reflective LCD screen
that's specially coated and readable in direct sunlight, you'll want to
make the screen as visible as possible)
if flush-mounting the head, make sure you choose an area that's
•
well-ventilated; poor ventilation may cause overheating, resulting
in potential backlighting problems
Yoke mounting
For yoke mounts, leave ample room—usually two inches—all around the
sides and top to avoid crowding the unit. Also allow a clearance of at least
2½ inches in the rear just for the cables and connectors. For the recom-
mended yoke-mount installation dimensions, see Figure 1, and Figure 2.
Before drilling holes, rotate the unit to the desired angle to ensure proper
clearance for cables and operation of the unit.
