IMPORTANT SAFETY INSTRUCTIONS
1. This manual contains important safety and operating instructions. Before using the battery charger, read all
instructions, cautions, and warnings on the battery charger, the battery, and the product using the battery.
2. This charger has been designed to only charge flooded, lead-acid batteries. Read and understand all setup
and operating instructions before using the battery charger to prevent damage to the battery and to the
charger.
3. Do not touch non-insulated parts of the output connector or the battery terminals to prevent electrical shock.
4. During charge, batteries produce hydrogen gas which can explode if ignited. Never smoke, use an open
flame, or create sparks in the vicinity of the battery. Ventilate well when the battery is in an enclosed space.
5. Do not connect or disconnect the battery plug while the charger is on. Doing so will cause arcing and
burning of the connector resulting in charger damage or battery explosion.
6. Lead-acid batteries contain sulfuric acid which causes burns. Do not get in eyes, on skin, or on clothing. In
cases of contact with eyes, flush immediately with clean water for 15 minutes. Seek medical attention
immediately.
7. Only factory qualified personnel can service this equipment. De-energize all AC and DC power connections
before servicing the charger.
8. The charger is not for outdoor use.
9. Do not expose the charger to moisture. Operating conditions should be 0º to 104º F; 0 to 70% relative
humidity.
10. Do not operate the charger if it has been dropped, received a sharp hit, or otherwise damaged in any way.
11. For continued protection and to reduce the risk of fire, install chargers on a floor of non-combustible material
such as stone, brick, or grounded metal.
WARNING: The shipping pallet must be removed for proper and safe operation.

TWO STACKED CHARGERS, RIGHT SIDE VIEW
METAL STRAP
INSTALLATION
WARNING: The shipping pallet must be removed for proper and safe operation.
Location
For maximum trouble-free service, choose a location which is free of excess moisture, dust,
and corrosive fumes. Also, avoid locations where temperatures are high or where liquids will
drip on the charger. Do not obstruct the ventilating openings or the space under the charger.
Mounting Wall Cabinet Chargers
The charger must be mounted on a wall or stand in a vertical position. The lower part of the
charger must be at least 24” from the ground and/or the charger below and the upper part 36”
from the ceiling. The minimum distance between two chargers must be12”.
The charger will be installed with four 5/16” bolts or with the bracket supplied. See the Wall
Mounting Dimensions section at the end of this manual for proper bolt pattern.
Placing Floor Cabinet Chargers
Allow at least six (6) inches of clearance at rear and sides of the charger for air circulation.
Stacking Multiple Floor Cabinet Chargers
These chargers can be stacked up to a maximum of 3 units high. Chargers are not designed
to be stacked side by side due to ventilation requirements.
1. Position the first charger so that a minimum of 6 inches of space is between the charger
and any wall, and 12 inches between the charger and any other chargers or equipment.
2. Place the second charger on top of the first. Align the bolt holes on each charger.
3. Fasten both charger cabinets together securely using 3/8” bolts and nuts.
NOTE: the two bolts toward the back of the
charger may be omitted if an after market metal
strap (about 8 inches) is used to secure both
chargers. Remove existing 1/4" screws of the
chargers' sides and attach strap with screws.
Refer to picture.
Hardware kit # X225-99-0-2 can be ordered to
attach two chargers.
4. Repeat steps 2 and 3 for the third charger.
5. Stacked chargers must be fastened to the
wall using devices suitable for the wall
construction and the bolt holes at the top of
the highest charger.
NOTE: Ambient temperature at all levels cannot exceed 104OF / 40OC.

Electrical Connections
To prevent failure of the charger, be sure it is connected to the correct line voltage.
On three phase units
Connect all chargers as follows:
Phase A to L1 (fuse block)
Phase B to L2 (fuse block)
Phase C to L3 (fuse block)
Connecting Input Power
WARNING: Make sure the power to the charger is OFF and the battery is disconnected
before connecting the input power to the terminals of the charger.
Connect the input power to the appropriate terminals, including ground. Follow your local
electrical or National Electric Code in making these connections.
AC Connection
The user must provide suitable branch circuit protection and a disconnect method from the AC
power supply to the charger to allow for safe servicing.
Plug Polarity
The charging cable is connected to the DC output of the charger with the positive lead marked
RED. The output polarity of the charger must be strictly observed when connecting to the
battery (read warning above).
Improper connection will open the DC fuse.
Grounding the Charger
DANGER: FAILURE TO GROUND THE CHARGER COULD LEAD TO FATAL ELECTRIC
SHOCK. Follow National Electric Code for ground wire sizing.
Connect a grounding conductor to the lug provided on the horizontal support panel. This lug is
marked as shown:

DESCRIPTION OF OPERATION
General
Legacy®Insight™ chargers are microprocessor-controlled. The processor calculates the
battery’s capacity so that the charging profile can be automatically adapted to the battery’s
actual state over a wide range of capacities. The charging coefficient is maintained absolutely
on all types of batteries. Legacy®Insight™ chargers adapt to the battery’s capacity and its
discharge level.
Legacy®Insight™ chargers can easily be set to charge flooded batteries used in cold or
freezer storage applications, ionic or opportunity profiles. This battery charger is also designed
to charge flooded and sealed lead-acid storage batteries within the range of the cell and
ampere-hour rating as marked on the nameplate.
Beginning the Charge
When a battery is connected to the charger, the control board senses voltage and after a 20
second delay, the charger energizes.
Charging
Charging current is determined by the battery voltage and interaction of the charger. Charging
current declines automatically as battery voltage rises during the charge. As the battery
charges, the LCD display will output various charge parameters including the percentage of
battery capacity.
AC Power Fail
If the AC power fails with a battery connected to the charger during a charge cycle, the charger
will reset and start a new charge cycle when power is restored. All charger settings as well as
the time and date are preserved.
Series Charging
In series charging, the voltages of both batteries add up and must match charger’s nameplate
rating. The charger’s ampere-hour rating must be equal to each of the batteries’ ampere-hour
rating. Charge cycle will not start unless both batteries are connected.

GLOSSARY
Charging Coefficient
The ratio of the number of ampere-hours restored during charging to the number of ampere-
hours consumed during discharge.
Charging Profile
The charging profile defines the rate of current charge over time. The charger adapts to the
battery’s age and level of discharge. Controlling the overcharge coefficient, whatever the
battery’s discharge level, reduces the amount of electricity consumed.
Cold Storage
This is a charging profile that allows the configuration of the charger for use with batteries in
cold storage application. The profile is an IEI (constant current, constant voltage, constant
current) type with a number of user configurable parameters.
Equalization Charging
Equalization charging, performed after normal charging, balances the electrolyte densities in
the battery’s cells.
IGBT
The IGBT controls the charger output by rapidly switching the transformer primary at 20 to 30
kHz.
Ionic Profile
Also called “ionic mixing”. This type of charging profile consists of sending short pulses of
current to stimulate gas formation in the active material, causing sulfuric acid to be distributed
outside the plates. This system of mixing the electrolyte enables more rapid charging of
flooded cell batteries subject to very high demands and balances out differences in density,
homogenizing the electrolyte across the surface of the plates.
