FIRST AID AND SAFETY
CYCLE-SENTRY
If your unit is equipped for CYCLE-SENTRY
operation, the unit may start automatically at
any time when the unit is turned on and the
CYCLE-SENTRY is selected.
ELECTRIC STANDBY
On Model 50 units, the unit may start
automatically at any time when the unit is
switched on, connected to live electric power
and/or the electric operation is selected.
Be sure to switch the unit off before opening
the doors or inspecting any part of the unit.
ELECTRICAL HAZARD
Units with electric operation
or electric standby
present a potential electrical hazard. Always
disconnect the high voltage power cable before
working on the unit.
BATTERY INSTALLATION AND CABLE
Routing
WARNING: Improperly installed battery could
result in a fire or explosion! A Thermo King
approved battery must be installed and properly
secured to the battery tray.
WARNING: Improperly installed battery cables
could result in fire or explosion! Battery cables
must be installed, routed and secured properly
to prevent them from rubbing, chaffing or making
contact with hot, sharp or rotating components.
WARNING: Do not attach fuel lines or any
additional wiring harnesses to the battery cables
as this could cause an electrical fire!
CAUTION: Do not connect other manufacturer’s
equipment or accessories to the Thermo King
unit. This could result in severe damage to
equipment and void the warranty!
CAUTION: Set all unit electrical controls to the
OFF position before connecting battery cables
to the battery to prevent unit from starting
unexpectedly and causing personal injury.
CAUTION: Always wear protective clothing,
gloves and eye wear when handling and
installing batteries. Battery acid can cause
serious burns when exposed to eyes or skin. If
battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters
your eye, immediately flood it with running cold
water for at least twenty minutes and get
medical attention immediately.
CAUTION: Always cover battery terminals to
prevent them from making contact with metal
components during battery installation. Battery
terminals grounding against metal could cause
the battery to explode.
WARNING!
Electric welding generates high amperage
currents which can damage electrical and
electronic components. To minimize
damage, prior to any welding operation on
the vehicle, the microprocessor and unit
battery must be electrically disconnected
from the vehicle. Switch the Microprocessor
On/Off switch to Off. Remove the negative
battery cable. Remove all connectors from
the rear of the microprocessor. Close the
control box. Connect the welder ground
cable as close as possible to the area being
welded. When welding is completed,
remove the welder ground cable. Reconnect
the cables to the rear of the
microprocessor. Reattach the negative
battery cable. Switch the microprocessor
On/Off switch to On. Reset all alarms and
codes to previous settings. Run a full
Pretrip. A detailed procedure may be found
in Thermo King Service Procedure A26A.
