cord, remove connection from the vehi-

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 wire to the Negative
battery post
3. Connect the Positive (red) DC wire from
the charger to the Positive battery post
4. Position yourself and the free end of
the piece of wire attached to the Nega-
tive post as far away from the battery as
possible and then connect the Negative
(black) DC wire from the charger to the
free end of the piece of wire 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

cAUtion! when charging more than one
bank of batteries at the same time using
3 Stage charging, ensure that the batteries
in the banks are in a similar discharged
condition. if one bank is completely
discharged and another is almost fully
charged, the bank that is fully charged
will be subjected to over charge condition
during the time when the charger remains
in Boost Stage for charging the completely
discharged bank. if batteries are in dis-
similar states of charge, select DiP Switch
setting for "Battery with load."
Powering other Dc loads
The charger can be used as a power sup-
ply or as a DC UPS . For both these applica-
tions, first set the DIP Switch to "Battery
with load". (See under " Selecting the
type of Battery and charging Stages" on
page 11).
To use as a power supply, first switch
off the DC load. Connect the DC load
between the common Negative terminal
and one of the three Positive terminals.
ensure that the maximum current drawn
by the Dc load is below the maximum
current rating of the charger. Switch on
the charger and then the Dc load.
In a DC UPS (Un-interruptible Power Sup-
ply) , the charger simultaneously powers
the DC load as well as the battery. As long
as the AC power to the charger is avail-
able and the charger is working normally,
the charger will supply the DC load as well
as charge/float the battery. In case the AC
power fails or if the charger stops work-
