Mounting the GSI 10 Black Box Device
NOTICE
If you are mounting the device in fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
NOTE: Screws are included with the device, but they may not be suitable for the mounting surface.
Before you mount the device, you must select a mounting location, and determine what screws and other
mounting hardware are needed for the surface.
1 Place the black box device in the mounting location, and mark the location of the pilot holes.
2 Drill a pilot hole for one corner of the device.
3 Loosely fasten the device to the mounting surface with one corner, and examine the other three pilot-hole
marks.
4 Mark new pilot-hole locations if necessary, and remove the device from the mounting surface.
5 Drill the remaining pilot holes.
6 Secure the device to the mounting location.
Connection Considerations
When connecting this device to power and to other Garmin devices, you should observe these considerations.
• The power and ground connections to the battery must be checked to make sure they are secured and
cannot become loose.
• The cables may be packaged without the locking rings installed. The cables should be routed before the
locking rings are installed.
• After installing a locking ring on a cable, you should make sure the ring is securely connected and the o-ring
is in place so the power or data connection remains secure.
Connection Overview
NOTE: The cable connections to the GSI 10 device shown in this diagram are the only connections needed when
installing the device. All of the other connectors are not functional and should not be used.
