INTRODUCTION

This section contains the Supra 950MT electrical schematic wiring diagram.
The following general safety notices supplement the specific warnings and cautions appearing elsewhere in this
manual. They are recommended precautions that must be understood and applied during operation and mainte-
nance of the equipment covered herein.
Beware of unannounced starting of the fans and V-belts caused by the thermostat and the
start/stop cycling of the unit that may start automatically
Under no circumstances should ether or any other starting aids be used to start engine.
Under no circumstances should anyone attempt to repair the Logic or Display Boards! Should
a problem develop with these components, contact your nearest Carrier Transicold dealer for
replacement.
Observe proper polarity when installing battery, negative battery terminal must be grounded.
Reverse polarity will destroy the rectifier diodes in alternator. As a precautionary measure, dis-
connect positive battery terminal when charging battery in unit. Connecting charger in reverse
will destroy the rectifier diodes in alternator.
Under no circumstances should a technician electrically probe the processor at any point,
other than the connector terminals where the harness attaches. Microprocessor components
operate at different voltage levels and at extremely low current levels. Improper use of voltme-
ters, jumper wires, continuity testers, etc. could permanently damage the processor.
Most electronic components are susceptible to damage caused by electrical static discharge
(ESD). In certain cases, the human body can have enough static electricity to cause resultant
damage to the components by touch. This is especially true of the integrated circuits found on
the truck/trailer microprocessor.
