    DANGER
    Hazard of electric shock, explosion, or arc flash
    Batteries can present a risk of electric shock and high short-circuit current. The following precautions must be observed when working on batteries
    • Remove watches, rings, or other metal objects.
    • Use tools with insulated handles.
    • Wear protective glasses, gloves and boots.
    • Do not lay tools or metal parts on top of batteries.
    • Disconnect the charging source prior to connecting or disconnecting battery terminals.
    • Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electric shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not having a grounded supply circuit).
    Failure to follow these instructions will result in death or serious injury.
  7. Close the front door of the classic battery cabinet(s).
