There are 2 nylon standoffs in the hardware pack – these must be used to isolate the avionics
busbar from the panel itself, as the panel will be earthed. It will be necessary to countersink
the screw holes at each end of the busbar to allow the screws to thread into the nylon standoff.
Mount the avionics busbar to the panel and tighten the mounting screws firmly.
Unpack the instruments and radios
Each instrument box will have a Jabiru stock number written on the top in marker pen. Take
each instrument out of its box, cut the tagged end of the box off and discard the box. Write the
Jabiru stock number on the tagged end and put it aside – this information along with all other
instrument serial numbers will be entered on the
Aircraft Identification
form in this Manual.
Discard any “O” rings from around the instruments: these will not be required.
The
Microair
VHF radio and Transponder can be removed from their boxes at this time. Each
unit is wrapped in a silver electrostatic bag. Do
not
cut the bag open at the end, but rather cut
the bag open along the
side
of the bag and remove the unit. Cutting across the end of the
silver bag risks cutting into the face of the unit and must be avoided at all costs.
Unpack the
Microair
VHF radio/intercom and Transponder wiring harnesses.
If fitting a GPS unit you will need the appropriate mounting bracket and wiring harness.
If the GPS is a
Garmin
product the mounting
bracket must be removed from the end of the
clamp assembly and screwed to the Jabiru
panel mount bracket as shown at right.
To mount the
Garmin
296/495 in a Standard
panel, refer to the photo at right for drilling
dimensions:
If the GPS is an
AvMap
unit the supplied
panel mount bracket will be used.
If the GPS is any other brand or model refer
to the manufacturers literature for mounting
instructions.
