BATTERY CHARGER – ELECTRIC VEHICLES
• 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.
• Only trained technicians should repair or service the charger. Contact your nearest
• Each charger should have its own dedicated 15 or 20 ampere separately protected (circuit
breaker or fuse) single phase branch circuit, in accordance with all applicable electrical codes
for the location.
• Connect the charger AC supply cord to a properly grounded, three-wire outlet of the proper
voltage and frequency as shown on the charger.
• Do not use an adapter to plug the charger with a three-prong plug into a two-prong outlet.
Improper connection of the equipment-grounding conductor can result in a fire or an
• An extension cord or electrical outlet must accept a three-prong plug. Extension cord should
be a three-wire No. 12 AWG (American Wire Gauge) or No. 14 SWG (British Standard Wire
Gauge), and be as short as possible. The use of improper extension cord could result in fire
or an electrical shock.
• Do not operate the charger if it has received a sharp blow, was dropped, or otherwise
damaged in any way.
• Have worn, cut, or damaged power cords or wires replaced immediately.
• Do not use near fuels, grain dust, solvents, thinners, or other flammables. Chargers can ignite
flammable materials and vapors.
• Do not expose to rain or any liquid. Keep the charger dry.
• Never push objects of any kind into the charger through cabinet slots. They may touch
dangerous voltage points or cause an electrical short circuit that could result in fire or
• Do not connect a stationary charger to the receptacle if the charger cord, plug, or the vehicle
receptacle is broken, damaged, or does not make a good electrical connection. Fire or
personal injury can result. Have a qualified technician replace the parts.
• When the charger is on, the charger DC cord may be disconnected from the vehicle receptacle
slowly. Jerking or pulling the DC cord out quickly could cause arcing and burning that could
damage the plug and receptacle and could cause batteries to explode.
• Do not block or cover the charger ventilation slots. The slots provide ventilation and protect
the charger from overheating.
• Do not allow clothing, blankets, or other material 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 lightning strikes.
