3.13-2 Battery Charging Operation
Figure 3-17. Battery Charger
DANGER
Risk of electric shock - Do not immerse
the charger in water. Though the charger
is highly resistant to water, it is not
designed for immersion and an electric
shock can occur.
1. Provide adequate ventilation for the batteries and
charger. The convection cooled design requires
access to cooling air for proper operation. Do
not allow blankets or other materials to cover
the charger. Although the charger protects itself
against overheating, the charger cooling fins
should be cleaned if clogged with debris for best
performance.
WARNING
There could be a spark during charging.
Be careful when using fuels, solvents or
other flammables near the charger or
batteries.
2. Connect the power supply cord to a properly
grounded 100V/50 or 60Hz, 115V/50 or 60Hz, or
230V/50 or 60Hz socket. This charger automatically
senses and adjusts to the AC input voltage
range.
