QUICK START INSTRUCTIONS:

Check that the temporary label on top of the charger marked with
the profile setting matches your battery type. If not, see the
reprogramming section.

These chargers work very simply. Once connected and plugged
into AC power, the LED will flash red for a few seconds, then turn
steady red. When the cycle is 80% complete it will turn yellow,
and finally green when cycle is complete.

If the profile is set to maintain the battery(s), the LED will flicker
green. If the profile is set to shut off, the cycle will end with a
steady green. The LED may also flicker when it is at the high limit
of the charge cycle.

To discontinue charging, unplug AC power.

Look to the Trouble shooting section for any deviations from this.

EQUALIZATION:

When using multiple batteries in a series string, cells become
uneven during charge and discharge cycles. At least once a month
perform two charge cycles back to back, this will give a chance for
cells that are lagging behind to catch up, and is important to overall
battery performance. NOTE: This only needs to be done when
using Wet cell, or AGM settings with standard or extended
gassing/absorption cycles. (Switch #1 ON).

Please read complete instructions before proceeding.

SAFETY INFORMATION AC W IRING:

Before making AC connections, refer to the requirements on the
charger ID label. If your charger is not equipped with an AC plug,
for example, a 230 volt charger, have a qualified electrician install
one.

To reduce the risk of fire, use this charger only on branch circuits
that are protected by a circuit breaker or fuse, and that are adequate
to carry the power drawn by the charger. All wiring should be in
accordance with the National Electric Code, ANSI/NFPA 70, and
all local codes and ordinances.

This battery charger must be grounded to reduce the risk of electric
shock. 117 volt chargers are equipped with a grounding type plug,
230 volt chargers are shipped without a plug. Have a qualified
electrician install a properly grounded 3 wire plug.

DO NOT USE THIS CHARGER ON A TWO POLE
UNGROUNDED OUTLET OR ATTEMPT TO BREAK OFF
THE GROUND PRONG FOR USE ON A RECEPTACLE OR
EXTENSION CORD NOT HAVING A GROUND.

If an extension cord must be used, make sure it is in good
condition. Use a three conductor cord no smaller than the size
being used on the charger, and keep it as short as possible. The use
of an improper extension cord could result in a risk of a fire or
electric shock. Locate all cords so that they will not be stepped on,
tripped over, or otherwise subjected to damage or stress.

If your charger bears the mark, it conforms with the essential
requirements of the applicable EC directives for products placed
on the market in the European Economic Area.

OTHER SAFETY INFORMATION

Do not use charger if it shows signs of physical stress, or if DC
output leads or connector feel hot when used.

Do not disconnect the DC output clamps, or connector from the
batteries when the charger is on. The resulting arcing could cause
the batteries to explode.

Failure to unplug AC power before moving or driving equipment
will result in damage to cords, plugs and receptacles.

BATTERY SAFETY & CARE INFORMATION
Always wear protective eye shields and clothing when working
with batteries. Batteries contain acids which can cause bodily
harm. Do not put wrenches or other metal objects across the
battery terminal or battery top. Arcing or explosion of the battery
can result. Do not wear jewelry when working around batteries.
Arcing can cause severe burns.

The tops of the batteries and battery hold downs must be kept clean
and dry at all times to prevent excessive self discharge and flow of
current between the battery post and frame.

With wet cell batteries, maintain the proper electrolyte level by
adding water when necessary. Never allow the electrolyte level to
fall below the top of the battery plates. Electrolyte levels fall
during discharge and rise during charging. Therefore, to prevent

the overflow of electrolyte when charging, add water only after
the batteries have been fully charged, or just enough to cover
the plates if discharged. Old batteries require more frequent

additions of water than do new batteries.

Do not over discharge batteries. Excessive discharge can cause
polarity reversal of individual cells resulting in complete battery
