CHARGER OPERATION
See General Warning, Section 1, Page 1-1.
ý
DANGER
• The charging area must be ventilated. Hydrogen level in the air must never exceed 2%. The
total volume of air in the charging area must be changed five times per hour. Exhaust fans
should be located at the highest point of the roof. Contact a local HVAC engineer.
• Do not charge the vehicle batteries with the vehicle covered or enclosed. Any enclosure or
cover should be removed or unzipped and pulled back when batteries are being charged. An
accumulation of hydrogen gas could result in an explosion.
ý
WARNING
• Do not bypass the sense lead fuse (not applicable to Precedent vehicles).
• Prior to servicing the charger, disconnect the AC power supply cord from the wall outlet,
disconnect the DC cord from the vehicle, and remove the battery charger from the vehicle.
See Onboard Charger Removal on page 4-35.
• Do not connect the charger to battery packs that are not compatible with the DC output
voltage specified on the charger. Overheating and transformer burnout will result.
• Do not use a battery charger if the cord or plug is damaged in any way. Replace worn or
damaged parts immediately. Failure to heed this warning could result in a fire, property
damage, severe personal injury, or death.
• Do not use a battery charger if it has received a sharp blow, was dropped, or was otherwise
damaged. Make sure it is operating properly before putting it back in use.
• Each charger should have its own 15 or 20 ampere branch circuit protection (circuit breaker
or fuse), in accordance with the National Electrical Code ANSI/NFPA 70, and local codes and
ordinances. Improper AC supply circuit protection may result in a fire.
• Improper connection of the equipment-grounding conductor can result in an electrical shock.
• Do not use an adapter to plug charger into a two-blade outlet or an extension cord. AC outlet
must accept grounded three-blade plug. The use of an extension cord could result in fire or
electric shock.
• Do not operate a battery charger if it has received a sharp blow, was dropped, or was
otherwise damaged. Make sure it is operating properly before putting it back in use.
• Chargers can ignite flammable materials and vapors. Do not use near fuels, grain dust,
solvents, thinner, or other flammables.
• Keep charger dry – Do not expose to rain.
• Do not block or cover the charger ventilation slots. The slots provide ventilation and prevent
the charger from overheating.
• Do not allow clothing, blankets, or other materials to cover the charger.
• Do not allow the charger to operate for more than 30 minutes at 19 or more amperes.
• Install surge arrestors on incoming AC power lines. Surge arrestors will help protect electrical
components in the charger and on the vehicle from all but direct or close lightening strikes.
AC POWER CONNECTION
The AC line to which the charger is to be connected must be of the proper AC input voltage for the charger
and must be capable of supplying sufficient current.
