Refer to the battery manufacturer documentation for specific battery safety instructions. The following are
general guidelines.
WARNING! Correct polarity must be observed when connecting battery leads.
WARNING! Special safety precautions are required for procedures involving handling, installing, and
servicing batteries. Observe all battery safety precautions in this manual and in the battery instruction
manual. These precautions should be followed implicitly at all times.
WARNING! A battery can present a risk of electrical shock and high short circuit current. Servicing of
batteries should be performed or supervised only by properly trained and qualified personnel
knowledgeable about batteries and the required precautions.
The following precautions should be observed when working on batteries:
• Remove watches, rings, and other metal objects.
• Eye protection should be worn to prevent injury from accidental electrical arcs.
• Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed. Ensure that wrenches with more than one working end have only one
end exposed.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Risk of explosion if battery is replaced with an incorrect type or if polarity is reversed.
Recommended to replace batteries with the same manufacturer and type, or equivalent.
• Dispose of used batteries according to the instructions provided with the batteries. Do not dispose
of batteries in a fire. They may explode.
• ALWAYS FOLLOW THE BATTERY MANUFACTURER'S RECOMMENDATIONS AND SAFETY
INSTRUCTIONS.
DANGER! This equipment may be used in conjunction with lead-acid batteries. Working near lead-acid
batteries is dangerous!
In addition to the hazard of electric shock, gas produced by batteries can be explosive and sulfuric acid
can cause severe burns.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes, and is toxic.
• Batteries contain sulfuric acid.
• Batteries generate explosive gases during normal operation. Systems containing batteries should
never be installed in an airtight room or space. Only install in a ventilated environment.
• Batteries are an energy source that can produce high amounts of electrical current.
