Figure 1−1 Lockout/Tagout; Safety Precautions - Carrier VECTOR 6500 Operation & Service Manual

1.1 SAFETY PRECAUTIONS

Your Carrier Transicold refrigeration unit has been
designed with the safety of the operator in mind. During
normal operation, all moving parts are fully enclosed to
help prevent injury. During all pre-trip inspections, daily
inspections, and problem troubleshooting, you may be
exposed to moving parts. Please stay clear of all moving
parts when the unit is in operation and when the Main
Power Switch is not in the OFF position.
CAUTION
Under no circumstances should a techni-
cian electrically probe the microprocessor
at any point, other than the connector termi-
nals where the harness attaches. Micropro-
cessor components operate at different
voltage levels and at extremely low current
levels. Improper use of voltmeters, jumper
wires, continuity testers, etc. could perma-
nently damage the microprocessor.
CAUTION
Most electronic components are suscepti-
ble to damage caused by electrical static
discharge (ESD). In certain cases, the hu-
man body can have enough static electric-
ity to cause resultant damage to the compo-
nents by touch. This is especially true of the
integrated circuits found on the micropro-
cessor.
Automatic Start-Stop
Your refrigeration unit is equipped with auto-start in both
Start-Stop and Continuous Operation. The unit may
start at any time the Main Power Switch is not in the OFF
position. A buzzer will sound for 5 seconds before the
unit is started. When performing any check of the
refrigeration unit (e.g., checking the belt, checking the
oil), make certain that the Main Power Switch is in the
OFF position.
Engine Coolant
The engine is equipped with a pressurized cooling
system including a pressurized coolant bottle. Under
normal operating conditions, the coolant in the engine
and radiator is under high pressure and is very hot.
Contact with hot coolant can cause severe burns. Do
not remove the cap from a hot radiator or bottle. If the
cap must be removed, cover it with a rag and remove
very slowly in order to release the pressure without
spray.
SECTION 1
SAFETY PRECAUTIONS
Refrigerants
The refrigerant contained in the refrigeration system of
this unit can cause frostbite, severe burns, or blindness
when in direct contact with the skin or eyes. For this
reason (and because of legislation regarding the
handling of refrigerants) we recommend that you
contact your nearest Carrier Transicold authorized
repair facility whenever service of the refrigerant system
is required.
Battery
This unit is equipped with a lead-acid type battery. The
battery normally vents small amounts of flammable
hydrogen gas. Do not smoke when checking the battery.
A battery explosion can cause serious physical harm
and/or blindness.
Standby Power
Be aware of HIGH VOLTAGE supplied at the power
plug. Even with the unit off, power is present from the
plug to the inside of the control box. Whenever practical,
disconnect the high voltage source when performing
service or maintenance procedures and lockout/tagout
the receptacle in accordance with your companies
procedures. The recommended lockout device (Carrier
part number 07−60129−00) is shown in Figure 1−1.
