Caution: Non-Standard Radio Installations; Caution: Negative Ground Supply - Tait TM8105 User Manual

NFPA 58. This standard states that the radio equipment
installation must meet the following requirements.
I The space containing the radio equipment shall be
isolated by a seal from the space containing the LP
gas container and its fitting.
I Outside filling connections shall be used for the LP
gas container and its fittings.
I The LP gas container space shall be vented to the
outside of the vehicle.

Caution: Non-Standard Radio Installations

The installation U-bracket described in this guide has
been designed so that there is enough airflow around
the radio to provide cooling.
If a non-standard installation method is used, care must
be taken that sufficient heat can be dissipated from the
radio heatsink fins and the bottom surface of the radio
chassis.
For this to be achieved, there must be a gap of more
than 10mm (0.4 inch) between the bottom surface of
the radio chassis and the mounting surface. This is illus-
trated in the following diagram.

Caution: Negative Ground Supply

TM8100 radios are designed to operate only in a nega-
tive ground system.
