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

failure. Re-charge batteries as soon as possible after a deep
discharge, but not if they are warm, allow a cooling down period.

Provide adequate ventilation when charging batteries. Chargers can
ignite flammable materials and vapors. Do not use near fuels,
grain, dust, solvents, or other flammables.

Do not charge batteries in excessively hot temperatures; wait till
the cool of the evening.

PRE CHARGE INFORMATION:

Mount the charger in the desired location, any orientation. Allow
space for the charger to dissipate heat, it will get hot while in use.
Do not seal the charger in an air tight compartment. Do not cover
the charger with any material. NOTE: The OB models are NOT
water proof, they are water resistant. This means they cannot
withstand immersion, or continuous exposure from pressure
washers, or heavy rain.

DRIVE LOCKO UT OPTION:

If your charger has an extra pair of small wires with a connector,
spade terminals, or just bare wires, it has this option. These wires
connect to your equipment if it has this feature. The purpose is to
disable the drive mechanism of the equipment when the charger is
plugged in so it cannot be moved and cause damage to the AC cord
and receptacle. These wires do not have to be connected for the

charger to work.

REMOTE LED OPTION:

If your charger has this option, install as shown:

Connect the red charge lead to battery positive, black to

When batt eries are connected in

When batt eries are connected in

negative. But before, make sure the battery pack is of the same
voltage rating of the charger. If you are unsure, count the number
of cells on the battery pack and multiply by two. This figure should
be the same as the DC voltage rating of the charger. (see ratings
label on charger) Charging a battery with a lower voltage rating
than the charger will cause damage to batteries, charger, and can
create an explosive atmosphere.

Make sure the AC cord, DC output leads, terminals,
connectors, or clamps are all in good working condition. Do not
use the charger if there are any signs of stress or damage, or if
wires are cut or have damaged insulation. Using this charger with
any of these symptoms could result in a fire, property damage, or
personal injury. Have a qualified service person make the
necessary repairs. Repairs should not be made by people who are
not qualified.

Illustration of series and parallel battery connections:

Parallel Series

Parallel the battery amp hour
capacity is additive and the
voltage remains t he same.
Example: two 180 amp hour
12 volt batteries would equal
12 volts and 360 amp hour capacity

Series t he voltage is additive and
the battery amp hour
capacity remains the same.
Example: two 180 amp hour
12 volt batteries would equal
24 volts and 180 amp hour capacity

REPROGRAMM ING:

Disconnect the charger from the batteries, and unplug the power
cord. Remove the four bolts holding the covers on. Open the side
with the LED and remove paper insulator.

Select the switch configuration that most closely matches your
application. Whether choosing maintenance mode, or shut off is a
personal preference, however the maintenance mode assures
batteries will remain charged and won’t self discharge.
IMPORTANT: Use switch numbers as a guide, as some boards
may be upside down, and reversed.

Replace paper insulator and reassemble, making sure not to pinch
any wires in the covers.

NOTE: The #1 position is designated for batteries requiring long
finish rates. If your performance is poor, it could be the batteries
are being undercharged. Verify with specific gravity readings on
wet cells.

US Battery, and Full River are two brands that benefit from
longer charge cycles.
