INSTALLATION IN VEHICLES POWERED
BY LIQUEFIED (LP) GAS
Radio installation in vehicles powered by liquefied petroleum gas
with the LP gas container in the trunk or other sealed-off space
within the interior of the vehicle must conform to the National Fire
Protection Association Standard NFPA 58 which requires that:
• Space containing radio equipment shall be isolated by a seal from
the space containing the LP gas container and its fittings.
• Outside filling connections shall be used for the LP gas container.
• The LP gas container space shall be vented to the outside of the
vehicle.
INSTALLATION
RUNNING CABLES
To assure the feasibility of the planned cable routings, it is suggested
that the cables be run before mounting the radio. The Orion mobile
radio may be installed as a Front Mount, Remote Mount or Cassette
Mount. The type of mount, the application and the options to be
installed should be considered when planning the cable runs. Figures 5-
12 provide Interconnection Diagrams for typical installations. Figures
5-12 should be referenced throughout this manual and throughout the
installation.
Be sure to leave some slack in each cable going to the radio so that the
radio may be pulled out for servicing with the power applied and
antenna attached. Coil any surplus cables and secure them out of the
way. Try to route the cables away from locations where they will be
exposed to heat (exhaust pipes, mufflers, tailpipes, etc.), battery acid,
sharp edges or mechanical damage or where they will be a nuisance to
automobile mechanics, the driver or passengers. Keep wiring away from
electronic computer modules, other electronic modules and ignition
circuits to help prevent interference to these components and radio
equipment.
In addition, try to utilize existing holes in the firewall, trunk wall and
the channels above or beneath doors. Channels through door and
window columns that are convenient for running cables may also be
used, unless rigid or flexible conduit is to be installed for cable runs.
