Safety Precautions
15
• Don’t wear loose clothing or jewelry in the vicinity of moving parts. These can get in machinery, with
disastrous results. Don’t wear jewelry while working on electrical equipment. If your hair is long,
wear a head covering. Hair caught in a drill press, fan belt or other moving parts can cause serious
injury.
• Don’t stand on a wet floor while working on electrical equipment. Use rubber insulated mats placed
on dry wood platforms.
• Don’t lunge after a dropped tool. To do so may place you in a position of extreme danger.
• Don’t commence any operation until you have taken all the necessary steps to ensure that you are in
complete safety.
Battery Installation and Cable Routing
Battery Removal
This order is important because the frame is grounded to the negative battery terminal. If the negative
terminal is still connected, a complete circuit exists from the positive terminal of the battery to the frame.
Metal objects contacting the positive side and the frame simultaneously will cause sparks or arcing. If
there are sufficient hydrogen gases emitted from the battery, an explosion might occur, causing equipment
damage, serious injury, even death.
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.
DANGER: Disconnect the negative battery terminal (-) first when removing a battery. Connect
the positive terminal (+) first when installing a battery.
