IMPORTANT SAFETY INSTRUCTIONS
WARNING: THE SHIPPING PALLET MUST BE REMOVED FOR PROPER AND SAFE OPERATION.
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 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.

INSTALLATION
WARNING: The shipping pallet must be removed for proper and safe operation.
Location
For maximum safe operation, choose a location which is free of excess moisture, dust,
combustible material and corrosive fumes. Also, avoid locations where temperatures are high or
where liquids will drip on the charger. Do not obstruct the ventilation openings. Follow charger
warning label when mounting on or over a combustible surface. The recommended charger
mounting location should provide a radial distance of at least 28 inches away from the closest
top edge of the battery.
Cabinet Mounting
The charger must be mounted on a wall, stand, shelf or floor in a vertical position. The minimum
distance between two chargers must be 12 inches.
The charger will be installed with four 5/16 inch bolts or with the bracket supplied. See the
Mounting Dimensions section at the end of this manual for proper bolt pattern. Charger should
be permanently fastened in place.
For shelf mounting, part number 159-6LA22723 is required –two per charger.
NOTE: Ambient temperature at all levels cannot exceed 113°F (45°C).
Electrical Connections
To prevent failure of the charger, make sure it is connected to the correct line voltage.
Follow your local and National Electric Code (NEC) in making these connections.
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.
Connecting Input Power
Connect the input power to the appropriate terminals and apply appropriate torque as follow:

DC Plug Polarity
The charging cables are connected to the DC output of the charger with the red cable to the
positive bussbar, and the black cable to the negative bussbar. The red cable is terminated into
the “+” side of the battery connector, and the black cable is terminated into the “-“side of the
connector. The output polarity of the charger must be observed when connecting to the battery
(read warning above). Improper connection will open the DC fuses in the power modules.
DESCRIPTION OF OPERATION
General
IMPAQ™chargers are microprocessor-controlled. The processor is programmable to adapt to
a wide range of battery capacities so that the charging profile can accurately adjust for any
battery size. The charging coefficient is maintained absolutely on all types of batteries at various
discharge levels.
IMPAQ™chargers are designed to charge NexSys®, GelBloc, flooded and sealed lead-acid
batteries within the range of the cell and ampere-hour rating marked on the nameplate.
Attempting to charge other battery designs with this charger could cause damage to the battery.
Starting the Charge Cycle
When a battery is connected to the charger, the control board senses the voltage and after a
short delay, the charger starts charging the battery.
Charging Current
Charging current is determined by the battery voltage and its state of charge condition. 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
DC Volts rating. The charger’s ampere-hour rating must be equal to each of the battery’s
ampere-hour rating. Charge cycle will not start unless both batteries are connected.

GLOSSARY
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 Profile
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.
Gel-Bloc Profile
This charging profile is an IEI (constant current, constant voltage, constant current) charging
profile designed for gelled electrolyte type sealed lead acid batteries.
NXBLOC Profile
This charging profile allows charging of NexSys TPPL bloc batteries at rates of 0.2 to 0.7 C6.
NXSTND Profile
This charging profile allows charging of NexSys 2V batteries at rates of 0.20 to 0.25 C6.
Opportunity Profile
This charging profile is used when opportunity charging is desired. It includes a start rate of up
to 25% of the battery’s 6-hour rated amp hour capacity and requires an equalize charge
performed once a week. The weekly equalize charge can be programmed to run automatically.
Operation
During opportunity charging the user can charge the battery during breaks, lunch or any
available time during the work day. The Opportunity Profile allows the battery to be
safely charged while it is kept in a partial state of charge between 20% and 80% of the
6-hour rated capacity during the work week. Sufficient time should be scheduled after
the weekly equalize charge to check and maintain electrolyte levels and allow the
battery to cool to ambient temperatures.
Daily Charge
When using the Opportunity Profile, the Daily Charge option can be set to add
additional charging time every day if the work schedule allows. This option should be
considered only when the daily work demand requires additional capacity.
STD Flooded (IEI) Profile
The profile is an IEI (constant current, constant voltage, constant current) type with a number of
user configurable parameters.
VRLA Profile
This charging profile allows for valve regulated lead acid batteries to be charged. This charging
profile is an IEIE (constant current, constant voltage, constant current, constant voltage) type.

Owner’s Manual
AM-IMPAQ-OM

Equalization Charging
Equalization charging, performed after normal charging, balances the electrolyte densities in the
battery’s cells.
Refresh Charging
Refresh or maintenance charging enables the battery to be maintained at maximum charge all
the time that it is connected to the charger.
OPERATING INSTRUCTIONS
The IMPAQ™series of chargers are compatible with batteries of 12, 24, 36, 48, 60, 64, 72 and
80 volts (depending on the version supplied).
Battery recognition (voltage, capacity and state of charge) is accomplished automatically by the
microprocessor. Several charging profiles are available (Cold Storage, Gel-Bloc, NXBLOC,
NXSTND, Opportunity, STD Flooded [IEI] , VRLA) based on the configuration chosen by the
operator. Furthermore, equalization and refresh charges are integrated.
