IMPROPERLY MATCHED WITH THE CHARGER MAY BURST CAUSING PERSONAL INJURY AND DAMAGE
TO BATTERIES OR CHARGER.
Battery manufacturers frequently use the same battery cases for different battery types. Wet batteries have
removable cell caps. Water electrolyzed by discharging and charging the battery is replaced through these
openings. Sealed batteries are generally distinguished by non-removable cell caps. The physical appearance of
the battery case is frequently the same as a wet battery, though the cell caps are generally not removable. Refer
to the battery manufacturer's information panel on the battery case to determine the type battery you have. If the
information panel is missing or not legible, do not use the battery.
5. OFF-BOARD (SHELF) VERSUS ON-BOARD (BUILT-IN) CHARGERS
E-Series chargers are available in either off-board or on-board configurations. Chargers configured for on-board
use are denoted as such in the type field on the charger ratings label (for example, “wet/onbrd”).
E-Series

User’s Manual
5.1 Off-Board Chargers
Off-board chargers are designed to be used in shelf or portable applications. They include rubber feet. If the
AC input plug is connected to AC power, a new charge cycle automatically starts when the DC output is
connected to a battery pack of the proper voltage. Disconnecting and reconnecting AC power while the DC
output remains connected to a battery pack WILL NOT automatically start a new charge cycle (unless a
storage mode condition has been met). Disconnecting the DC output from the battery pack IS REQUIRED
to automatically start a new charge cycle.
5.2 On-Board Chargers
On-board chargers are designed to be mounted on electric vehicles/equipment. They include steel feet with
a pattern that provides numerous mounting options (see Section 6.1). If the DC output is connected to a
battery pack of the proper voltage, a charge cycle automatically starts when the AC input plug is connected
to AC power (unless a safety period of time has not passed since the successful completion of the previous
charge cycle). Disconnecting the DC output from the battery pack is NOT REQUIRED to automatically start
a new charge cycle.
6. LOCATION AND INSTALLATION
WARNING: DO NOT INSTALL THE CHARGER ON OR NEAR FLAMMABLE MATERIALS. POSITION
THE CHARGER ON A FOUNDATION OF STONE, BRICK, CONCRETE OR GROUNDED METAL.
WARNING: CHARGERS CAN IGNITE FLAMMABLE MATERIALS AND VAPORS. DO NOT USE NEAR
FUELS, GRAIN DUST, SOLVENTS, THINNERS, OR OTHER FLAMMABLES.
The charger may have been attached to a plywood board in the factory to protect it during shipping. If so remove
the plywood shipping board before installation and operation of the charger.
Proper installation of the charger is important in order to achieve good performance and to prevent damage to the
charger and batteries. The charger should be located in a clean, cool, dry, and well ventilated area. To permit
free airflow for convection cooling, allow 2 inches (5.08 cm) minimum between the charger ventilation openings
and any walls or other objects. Do not obstruct the airflow space around and beneath the charger. Do not allow
clothing, blankets, or other materials to cover the charger.
Install the charger in an area where the temperatures will remain within the range of -4 °F to 113 °F (-20 °C to 45
°C) and the relative humidity will remain below 95 percent (%). Exceeding these ranges will reduce the current
capacity and possibly the service life of the charger. If the charger will be operated outside of these ranges,
contact your dealer to verify if it will withstand these conditions and perform at the needed capacity.
Do not operate the charger with a damaged AC or DC cable or connector. Do not operate the charger if it has
received a sharp blow, was dropped, or was otherwise damaged in any manner. Contact your dealer.
WARNING: REPLACE WORN, DAMAGED, OR CUT ELECTRICAL CORDS AND PLUGS IMMEDIATELY.
WARNING: KEEP DRY; DO NOT EXPOSE TO RAIN OR SPRAY. FOR STORAGE, KEEP CHARGER IN A

7. AC INPUT
This charger must be connected to a single-phase nominal 120 Vac, 60 Hz AC power source with a voltage of
110 Vac to 132 Vac (charge times increase at lower AC voltages). The frequency must be 57 Hz to 63 Hz.
Circuit breaker or fuse protection for the AC outlet to which the charger is connected should allow 15A per
charger. Do not overload an electrical outlet.
This charger must be grounded to reduce the risk of electric shock. It is equipped with an AC cable with an
equipment-grounding conductor and a grounding-type connector. The connector must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with the National Electrical Code and all
local codes and ordinances.
DANGER: IMPROPER CONNECTION OF THE GROUNDING CONDUCTOR CAN RESULT IN A RISK OF
ELECTRIC SHOCK. DO NOT REMOVE GROUNDING PRONG FROM PLUG.
The conductor with insulation having an outer surface that is green, with or without a yellow stripe(s), is the
equipment-grounding conductor. If repair or replacement of the AC cable or connector is necessary, do not
connect the equipment-grounding conductor to a live terminal. Contact your dealer. This charger is equipped
with a grounding connector as illustrated in Figure 7-1 A, for use on a nominal 120 Vac, 60 Hz circuit. A
temporary adapter, as illustrated in Figures 7-1 B and C, may be used to plug this connector into a two-pole
receptacle as shown in Figure 7-1 C if a properly grounded outlet is not available (NOTE: use of an adapter as
shown in Figures 7-1 B and C is NOT permitted in Canada). The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet box.
DANGER: BEFORE USING THE ADAPTER AS ILLUSTRATED, BE CERTAIN THAT THE CENTER
SCREW OF THE OUTLET PLATE IS GROUNDED.

9. PROPER CARE OF DEEP-CYCLE MOTIVE POWER BATTERIES
Motive power battery packs are subjected to severe deep-cycle duty on a daily basis. Although these batteries
are designed to withstand such duty, the following precautions must be observed to obtain good performance and
maximum cycle life.
CAUTION: 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.
1. When installing new batteries, be sure the polarity of each battery and the overall battery pack is correct.
Otherwise, battery and/or charger damage can result.
2. New batteries should be given a full charge before their first use because it is difficult to know how long
the batteries have been stored.
3. New batteries and older batteries that have been in storage are not capable of their rated output until they
have been discharged and charged a number of times. Consult the manufacturer of your batteries for
more information.
4. DO NOT EXCESSIVELY DISCHARGE THE BATTERIES. Excessive discharge can cause polarity
reversal of individual cells resulting in complete failure shortly thereafter.
5. Maintain the proper electrolyte level of wet (flooded) batteries by adding water when necessary. Distilled
or deionized water is best for battery life. Never allow the electrolyte level to fall below the top of the
battery plates. Electrolyte levels lower during discharge and rise during charge. Therefore, to prevent the
overflow of electrolyte when charging, it is mandatory that water be added to cells AFTER they have been
fully charged – do not overfill. Old batteries require more frequent additions of water than new batteries.
6. Hard crystalline sulfates form when batteries in storage are not maintained in a charged active state.
Internal self discharge can bring about the start of this condition in as little as three days in warm
temperatures. Batteries not maintained and allowed to sit in storage will self discharge, sulfate and lose
capacity. Repeated charging without using the batteries between charges can recover some of the lost
power, range, and life, but some permanent loss should be expected.
7. Cold batteries require more time to fully charge. When the temperature falls below 65°F, the batteries
should be placed on charge as soon after use as possible.
8. The tops of batteries and battery hold downs must be kept clean and dry at all times to prevent excessive
self discharge and the flow of current between the battery posts and frame. Electrolyte spilled on
batteries never dries or evaporates.
9. All connections to batteries must be maintained clean and tight. Due to heating and discharge rates,
bolted connections loosen over time. Re-tighten the connections twice yearly to the torques specified by
the battery manufacturers.
10. Follow all operating instructions, cautions, and warnings as specified in this manual, on the charger, in the
battery manuals, and in the vehicle manuals.
9.1 Personal Safety Precautions
1. Have someone within the range of your voice and close enough to quickly come to your aid when
you work near a lead-acid battery.
2. Ensure that ample fresh water and soap are nearby in case battery acid contacts your skin, clothing,
or eyes.
3. Wear complete eye and clothing protection. Avoid touching your eyes while working near a battery.
4. If battery acid contacts your skin or clothing, wash immediately with soap and water. If acid enters
your eye, immediately flush your eye with running cold water for at least 10 minutes, and get medical
attention immediately.
5. NEVER smoke or allow a spark or flame to be in the vicinity of a battery.
6. Be extra cautious to reduce the risk of dropping a metal tool onto a battery. It could spark or short
circuit the battery or other electrical components that could cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
battery. A battery can produce a short-circuit current that is high enough to cause a severe burn.
8. NEVER charge a frozen battery.

COULD CAUSE MALFUNCTION, FIRE, OR EXPLOSION.
Batteries must be well maintained for the charging system to operate properly. Follow battery manufacturer
instructions for battery maintenance. Check for loose connections or corrosion.
DC connections may become corroded over time. If the connections become corroded, they should be
cleaned as recommended by the battery manufacturer. After the connections have been cleaned, a battery
connection treatment should be applied to help prevent corrosion from reoccurring. Contact the battery
manufacturer for their recommendations.
Periodic cleaning and watering of non-sealed batteries is very important. Logging the water usage of nonsealed batteries is useful. As a battery ages, it will use more water.
