OPERATION
When the charger is switched on, the red LED lights up indicating that output voltage is available.
When the batteries are being charged or when the charger is supplying other DC load, the current fed
by the charger will be indicated by the ammeter.
When the batteries are discharged, they will draw charging current proportional to their discharged
condition (up to a maximum current rating of the charger) and this current draw will be shown by the
ammeter. When the batteries are fully charged, they will draw very low current ( may not be
registered by the ammeter ) to compensate for their self discharge.
Charging a Battery Installed in a Vehicle
Follow these steps when the battery is installed in a vehicle. A spark near a battery may
cause battery explosion. For safety and to reduce the risk of spark near the battery :
1.
Position AC and DC cords to reduce risk of damage by hood, door or moving engine parts
2.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons
3.
Check the polarity of the battery posts. A positive ( Pos, P, + ) battery post usually has a
larger diameter than a Negative ( Neg, N, - ) post
4.
Determine which post of the battery is grounded (Connected) to the chassis (Engine
Block). If the negative post is grounded to the Engine Block ( As in most vehicles ), see
sub paragraph 5. If the positive post is grounded, see sub paragraph 6
5.
For a negative grounded vehicle, connect the positive (red) DC cable from the charger to
the positive of the battery post. Connect the negative (black) DC cable from the charger to
a section of heavy gauge metal part of the frame or engine block which is away from
battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
6.
For a positive grounded vehicle, connect the negative (black) DC cable from the charger to
the negative of the battery post. Connect the positive (red) DC cable from the charger to a
section of heavy gauge metal part of the frame or engine block which is away from
battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
7.
Connect the charger AC power cord to the AC outlet
8.
When disconnecting the charger, turn switches to off, disconnect AC power cord, remove
connection from the vehicle chassis and then remove connection from the battery terminal
Charging a Battery outside the Vehicle
Follow these steps when the battery is outside the vehicle. A spark near the battery may
cause battery explosion. For safety and to reduce risk of spark near the battery, connect the
charger as follows :
1.
Check the polarity of the battery posts. A positive ( Pos, P, + ) battery post usually has a
larger diameter than a Negative ( Neg, N, - ) post
2.
Attach a piece of at least 3” of AWG #6 insulated battery cable to the negative battery post
3.
Connect the positive (red) DC cable from the charger to the positive battery post
4.
Position yourself and the free end of the piece of cable attached to the negative post as far
away from the battery as possible and then connect the negative (black) DC cable from the
charger to the free end of the piece of cable attached to the negative battery post
5.
Do not face the battery when making the final connection
6.
Connect the charger AC power cord to the AC outlet
7.
When disconnecting the charger, always do so in reverse sequence of connecting procedure
and break the first connection while standing as far away from the battery as practical
