SECTION TWO - Installation
T
his chapter includes all the information needed to install the 961. It
begins with a review of the system components and then provides infor-
mation on basic installation and powering on the unit. The rest of the
chapter describes how to wire the unit, install the antenna, and trouble-
shoot. Proper installation of the Northstar 961 is of utmost importance to
accurately receive and effectively use GPS signals under a wide variety of
weather conditions.
Safety considerations
WARNING!
Be sure to turn the power off at the main switchboard
before starting the installation. Further, it is highly
recommended that you post a sign by this switch tell-
ing others to keep power off while you’re performing
the installation. If power is left on or turned on during
the installation, fire, electrical shock, or other serious
injury may occur.
WARNING!
Be sure that the voltage of the power supply is
compatible with the unit’s voltage rating, which
can be found on the label at the rear of the unit.
Connecting to the wrong power supply can
result in fire or damage to the equipment.
Be sure to ground the equipment in order to pre-
vent electrical shock or mutual interference.
WARNING!
Be sure to use the proper fuse. Using the incorrect
fuse can result in fire or damage to the equipment.
CAUTION!
Make sure that the 961 does not interfere with
any of the on-board systems. Check all other
systems to ensure that their performance
doesn’t degrade when the unit is turned on.
CAUTION!
The 961 processor can only be mounted horizontally
due to its rubber vibration mounts.
CAUTION!
If you must cut the processor’s 10-foot power
cord shorter, be sure to keep the external fuse
intact. If the power cable must be longer than 10
feet, use a heavier gauge wire for those applica-
tions and be sure to use an external fuse.
