SAFETY INSTRUCTIONS AND WARNINGS
SAFETY INSTRUCTIONS AND WARNINGS
FOR OPERATION OF BATTERY
CHARGING EQUIPMENT
IMPORTANT – READ AND
UNDERSTAND THESE
INSTRUCTIONS. DO NOT
LOSE THEM. ALSO READ
OPERATING/INSTRUCTION
MANUAL BEFORE
INSTALLING, OPERATING,
OR SERVICING THIS
EQUIPMENT.
A. General
Battery charging products can cause serious
injury or death, or damage to other equipment or
property, if the operator does not strictly observe
all safety rules and take precautionary actions.
Safe practices have developed from past experience
in the use of charging equipment. These practices
must be learned through study and training before
using this equipment. Anyone not having
extensive training in battery charging practices
should be taught by experienced operators.
Only qualified personnel should install, use, or
service this equipment.
B. Shock Prevention
Bare conductors, or terminals in the output circuit,
or ungrounded, electrically-live equipment can
fatally shock a person. To protect against shock,
have competent electrician verify that the
equipment is adequately grounded and learn what
terminals and parts are electrically HOT.
The body’s electrical resistance is decreased when
wet, permitting dangerous current to flow through the
body. Do not work in damp area without being extreme-
ly careful. Stand on dry rubber mat or dry wood and
use insulating gloves when dampness or sweat cannot
be avoided. Keep clothing dry.
1. Installation and Grounding of Electrically Powered
Equipment – Electrical equipment must be installed
and maintained in accordance with the National
Electrical Code, NFPA 70, and local codes. A
power disconnect switch must be located at the
equipment. Check nameplate for voltage and
phase requirements. If only 3-phase power is
available, connect single-phase equipment to only
two wires of the 3-phase line. DO NOT CONNECT
the equipment grounding conductor (lead) to the
third live wire of the 3-phase line as this makes the
equipment frame electrically HOT, which can cause
a fatal shock.
If a grounding lead (conductor) is part of the power
supply cable, be sure to connect it to a properly
grounded switch box or building ground. If not part
of the supply cable, use a separate grounding lead
(conductor). Do not remove a ground prong from
any plug. Use correct mating receptacles. Check
ground for electrical continuity before using
equipment.
The grounding conductor must be of a size equal
to or larger than the size recommended by Code or
in this manual.
2. Charging Leads – Inspect leads often for damage
to the insulation. Replace or repair cracked or worn
leads immediately. Use leads having sufficient
capacity to carry the operating current without
overheating.
3. Battery Terminals – Do not touch battery terminals
while equipment is operating.
4. Service and Maintenance – Shut OFF all power at
the disconnect switch or line breaker before
inspecting, adjusting, or servicing the equipment.
Lock switch OPEN (or remove line fuses) so that
the power cannot be turned ON accidentally.
Disconnect power to equipment if it is to be left
unattended or out of service.
Disconnect battery from charger.
Keep inside parts clean and dry. Dirt and/or
moisture can cause insulation failure. This failure
can result in high voltage at the charger output.

SAFETY INSTRUCTIONS AND WARNINGS
C. Burn and Bodily Injury Prevention
The battery produces very high currents when short
circuited, and will burn the skin severely if in contact
with any metal conductor that is carrying this current.
Do not permit rings on fingers to come in contact with
battery terminals or the cell connectors on top of the
battery.
Battery acid is very corrosive. Always wear correct eye
and body protection when near batteries.
D. Fire and Explosion Prevention
Batteries give off explosive flammable gases which
easily ignite when coming in contact with an open flame
or spark. Do not smoke, cause sparking, or use open
flame near batteries. Charge batteries only in
locations which are clean, dry, and well ventilated.
Do not lay tools or anything that is metallic on top of
any battery. All repairs to a battery must be made only
by experienced and qualified personnel.
E. Arcing and Burning of Connector
To prevent arcing and burning of the connector
contacts, be sure the charger is OFF before connecting
or disconnecting the battery. (If the charger is
equipped with an ammeter, the ammeter should not
indicate current flow.) Always connect battery before
turning charger ON.
F. Medical and First Aid Treatment
First aid facilities and a qualified first aid person should
be available for each shift for immediate treatment of
electrical shock victims.
EMERGENCY FIRST AID: Call
physician and ambulance
immediately. Use First Aid
techniques recommended by the
American Red Cross.
DANGER: ELECTRICAL SHOCK
CAN BE FATAL. If person is
unconscious and electric shock
is suspected, do not touch
person if he or she is in contact
with charging leads, charging
equipment, or other live electrical
parts. Disconnect (open) power
at wall switch and then use
First Aid. Dry wood, wooden
broom, and other insulating
material can be used to move
cables, if necessary, away from
person. IF BREATHING IS
DIFFICULT, give oxygen. IF NOT
BREATHING, BEGIN ARTIFICIAL
BREATHING, such as mouth-to-
mouth. IF PULSE IS ABSENT,
BEGIN ARTIFICIAL CIRCULATION,
such as external heart massage.
IN CASE OF ACID IN THE EYES, flush very well
with clean water and obtain professional medical
attention immediately.
G. Equipment Warning Labels
Inspect all precautionary labels on the equipment.
Order and replace all labels that cannot be easily
read.

DESCRIPTION OF EQUIPMENT
DESCRIPTION OF EQUIPMENT
Figure 3-1
The basic charging circuit is the mosfet inverter high
frequency-type with isolating transformer (s). This
design regulates charging current by allowing the
battery to determine its own charge cycle rate in
accordance with its state of discharge. It provides a
constant current-constant voltage-constant current
(IEI) charge that eliminates the possibility of over-
charging, even with line voltage variations of ± 10%
and allows the battery to finish at the proper current
regardless of battery age or gravity type.
The Eclipse II Plus provides opportunity battery
charging over a wide range of environmental
conditions. The charger will precisely charge your
battery based on battery temperature, type, and
size; by automatically adjusting its own output
charge characteristic within the power limits of the
chargers power circuit.
When applied with the Prestolite Power optional
Battery Identification Module (BID), the Eclipse II
Plus identifies a battery selected for opportunity
charging at the time of connection and adjusts its
output for that specific battery. During the charge
cycle, or duration of connection if used as an oppor-
tunity charger the Eclipse II Plus continuously moni-
tors the battery’s temperature via the BID and ad-
justs its output to match the battery temperature as
it changes throughout the charge cycle.
Upon connection of the battery, the Eclipse II Plus
reads the information programmed into the BID and
identifies the battery’s AH rating, cell size, type of
construction, electrolyte temperature, and pro-
grammed method of charge and adjusts its output
curve based on this information.
The Eclipse II Plus is internally protected against
overload and short circuits by both input and output
fusing, plus Prestolite’s unique curve monitoring
circuit periodically measures the output curve to
ensure that the voltage and current are within the
limits set at the factory.
Operating Modes
Ready Power enabled Eclipse II Plus chargers will
work like a normal Eclipse II Plus charger if it is set
to automatically start and a battery is plugged in
without a Battery Monitoring System. If a battery
with a BMS is connected, it will allow the BMS to
control its output.
If no BMS is present, the charger will read the infor-
mation that was programmed into the BID Module
during installation and charges the battery based on
an opportunity charging profile or a profile designed
to recharge a fully discharged battery in 8 hrs.
Valve regulated batteries of several types can also
be recharged at the 8 hour rates when equipped
with a properly programmed BID Module.
The AMETEK Prestolite Power Eclipse II product
line has been modified to meet the standards of
Navitas Lithium Batteries. The changes made are to
allow the charger to use CAN communication to
take direct commands from a Batteries’ BMS. The
charger follows the charge current requested by the
BMS and terminates upon request by the BMS.

DESCRIPTION OF EQUIPMENT
EC2000 Control
The extreme flexibility of the Eclipse II Plus lies in
the state of the art micro controller used in the
EC2000 charger control.
The EC2000 is made up of two main components:
the Control /Regulator Board, and the Keypad/
Display. The Control portion provides the basic
operating features of the charger, such as auto
start/stop, auto equalize, charge cycle review, real
time clock, communications, etc. The Regulator
portion actually controls the level of the chargers DC
output.
The Keypad/Display provides the user interface with
the charger. The durable membrane keypad is
impervious to moisture and mechanical shock. The
backlit 2 line 20 character LCD display constantly
shows the charger’s output volts, amps, and amp
hours returned during the charge cycle. The display
also provides the user with plain English messages
concerning charge cycle status.
Four bright LEDs shine through the keypad to keep
the user informed of charge status at a glance, even
from long distances. LEDs notify you that a charge
is in progress, that the battery is 80% charged,
equalize cycle, charge complete, and fault indica-
tion.
WARNING: Do not connect a
battery to this charger if any lamp
is lit. Do not disconnect a battery
from this charger while a charge
is in progress. Otherwise, damage
to charger, arcing and burning of
connector parts or a battery
explosion may result. Batteries
produce explosive gases. Keep
sparks, flame, and cigarettes
away. Ventilate when charging
in an enclosed area. Always shield
eyes when working near batteries.

05/18/2021 13
Location
For best operating characteristics and longest unit life,
take care in selecting an installation site. Avoid
locations exposed to high humidity, dust, high ambient
temperature, or corrosive fumes. Moisture can
condense on electrical components, causing corrosion
or shorting of circuits (especially when dirt is also
present).
Adequate air circulation is needed at all times in order
to assure proper operation. Provide a minimum of 12
inches of free air space at both sides of the unit.
Make sure that ventilation openings are not obstructed.
Always remove the charger shipping skid from the unit
before installation. The charger must be installed over
a noncombustible surface such as concrete or metal.
Keep the charging area clear of all combustible materi-
al such as wood, paper, and cloth. When moving the
charger after the packing skid and box have been
removed, make sure that lifting forks do not damage
the charger panels or cables.
WARNING: SPARKS OR MOLTEN METAL
falling through open bottom can cause fire or
explosion.
•Install over noncombustible material such as
concrete or metal.
•Keep charging area clear of combustible
material.
Environmental Characteristics
Operating Characteristics 0°C to 40°C
(32°F to 104°F)
Operating Altitude To 2000 Meters
(6562 Feet)
Operating Humidity 80% up to 31°c,
decreasing to 50% at
40°C, non-condensing
80% up to 88°F
decreasing to 50% at
104°F, non-condensing
Grounding
The frame of the power source must be grounded for
personnel safety. Where grounding is mandatory un-
der state or local codes, it is the responsibility of the
user to comply with all applicable rules and regulations.
Where no state or local codes exist, it is recommended
that the National Electrical Code be followed.
In addition to the usual function of protecting personnel
against the hazard of electrical shock due to fault in the
equipment, grounding serves to discharge the static
electrical charges which tend to build up on the
surfaces of equipment. These static charges can
cause painful shock to personnel, and can lead to the
erroneous conclusion that an electrical fault exists in
the equipment.
If a charger is to be connected to the AC power supply
with a flexible jacketed cable, one having a separate
grounding conductor should be used. When included
in cable assembly, grounding conductor will be green,
green with a yellow stripe, or bare. When connecting
input power to charger (as instructed in Line Connec-
tion to Battery Charger section of this manual), connect
grounding conductor to equipment grounding terminal,
taking care to make a good electrical connection. Con-
nect other end of grounding conductor to the system
ground.
If, for any reason, an input cable which does not in-
clude a grounding conductor is used, the equipment
must be grounded with separate conductor. Minimum
size and color coding requirements must be in accord-
ance with any applicable state or local code, or the Na-
tional Electrical Code.
If metallic armored cable or conduit is used, the metal
sheathing or conduit must be effectively grounded as
required by state or local code, or the National
Electrical Code.
If a system ground is not available, the charger frame
must be connected to a driven ground rod (at least 8 ft
[2438 mm] long), or to a water pipe that enters the
ground not more than 10 ft (3048 mm) from the
charger. A grounding conductor must be connected to
the rod or pipe in a manner that will assure a
permanent and effective ground. The conductor must
be sized in accordance with any applicable state or
local code, or by the National Electrical Code. If in
doubt, use the same size conductor as is used for the
conductors supplying power to the charger.
WARNING: ELECTRIC SHOCK
HAZARD – Under no circumstance
should you use a grounding
conductor with a current carrying
capacity less than the ampere
rating shown in Table 4-1.

INSTALLATION
Special Considerations—Generators and
Backup Power Systems
On site power generation and backup power systems
create special considerations both because of the pow-
er quality itself and also the manner in which the load is
transferred between mains and backup (and reversion
to mains). If this installation will incorporate either on –
site generation or some other form of back up power,
please consult AMETEK Engineering for a review of the
planned system prior to implementation. AMETEK En-
gineering will review the system specifications and
make a determination as to whether any changes
would be required in order to provide coverage under
the standard warranty.
Charging Cable Connectors
If connectors are already attached to charging cables,
make sure that they are attached so that positive
charger polarity will connect to positive battery terminal.
If connectors must be attached to charging cables,
follow instructions supplied with connectors.
Consider the connectors auxiliary wiring when inspect-
ing it as these CAN chargers are designed to use those
wires to communicate to the BMS of the Lithium bat-
tery.
CAUTION: Make sure connectors are
securely attached to cables (good
solder joint or well tightened set screws,
whichever is applicable). Be certain
that positive charger cable will connect
to positive battery terminal. If necessary,
trace cables into charger to determine
polarity. The use of a DC voltmeter may
show polarity. Improper connections
will “blow” output fuse and may cause
other damage.
Pre-operation Checks
1. Inspect charger thoroughly for damage; loose
screws, nuts, or electrical connections.
WARNING: ELECTRICAL SHOCK
HAZARD – Before inspecting or
cleaning inside cabinet, turn OFF
and remove fuses of disconnect
switch (supplying AC power to
charger) and disconnect battery.
2. Remove all special tags that are tied to charger.
Keep tags with this manual for future reference.
Leave all precautionary and instruction labels in
place on charger. Carefully read and follow
instructions on all tags and labels. Make sure all
labels remain visible to anyone operating charger.
3. Make sure all charger cabinet panels are fastened
in place, to assure proper flow of ventilating air
through cabinet.
Pre-Operation Changes To The Factory
Control Settings
Typically few changes are required to be made if the
amp hour rating is sized to the battery and the voltage
rating is equal to or greater than the battery. However,
in some applications, some changes to the
programmable control settings may be desirable. The
most common changes are listed below:
TIME Factory Setting for Time is Eastern
Standard. (see Programming the
EC2000).
NO GASSING HOURS
Factory Setting is 0 (see Programming
the EC2000).
MAX BATTERY TEMPERATURE
Factory Setting is 150° F (see Pro
gramming the EC2000).
NOTE: It is advisable to check the day of the
week, date, month, and year for accuracy
AUTO EQUALIZE
Factory setting is ON (see Program
ming the EC2000).
AUTO EQUALIZE TYPE
Factory setting is by Cycle (see Pro
gramming the EC2000).
AUTO EQUALIZE COUNT
Factory setting is 05 (see Program
ming the EC2000).
The chargers START MODE will be AUTO by default
and this will charge a BMS lithium battery as well as
any battery without a BMS. The start mode can be
charged to BMS to only charge a lithium battery with a
BMS.

certain optional features, the operating
procedure may be modified.
Preliminary
1. Make sure that charger is installed and grounded as
instructed in this manual.
2. Turn on main fused disconnect switch that supplies
AC power to charger.
3. Maintain electrolyte level in batteries to be charged,
as instructed by battery manufacturer. The volume
of electrolyte will expand during the charge.
Therefore, to avoid overfilling, do not add water
until the battery has received at least an 80%
charge. This will usually be reached at the time
gassing starts.
Normal or Daily Charge
(For batteries with ampere-hour capacity within the
range shown on charger nameplate)
1. Insure that battery size matches the charger and/or
charger setting. (Number of cells is equal to or less
than the charger nameplate rating and ampere-hour
capacity is within charger nameplate rating.)
2. Securely engage the battery and charger
connectors.
3. The charger will display READING BID and update
the progress bar (2 to 7 seconds) as the data is
read into the charger.
4. After a short delay, the charger will turn on and the
“Charge in Progress” LED will light. The
alphanumeric display will indicate the cell size and
amp hour settings for the upcoming charge cycle.
Then it will display current charging cycle
information. “Verifying Battery” may appear for
several minutes if the mult-cell mode is on.
5. The “80% Charged” LED will light when the battery
has reached the gassing point.
6. When the charge termination point is reached, the
charger will turn off and the “Charge Complete” LED
will be lit. If an equalize charge has been selected,
the “Equalize” LED will be lit.
NOTE: To disconnect battery from charger
before charge is complete, press the
“Stop” key on the charger control panel.
WARNING: EXPLOSION HAZARD
- Do not connect or disconnect a
battery unless the “Charge in
Progress” LED is off; otherwise,
damage to charger, arcing and
burning of connector parts or a
battery explosion may result
(batteries produce explosive
gases). Keep sparks, flame,
and cigarettes away. Ventilate
when charging in an enclosed
area. Always shield eyes when
working near batteries.
Disconnect battery if charger is
to be turned off for prolonged
periods of time.
BMS Charging
Batteries with a Battery Monitoring System (BMS)
will communicate to the charger using CAN com-
munications. The BMS will control the charger to
complete the battery charging cycle.
The BMS also controls the state-of-charge infor-
mation on the charger control.

Batteries may need periodic equalizing to correct for
inequalities between cells that result from daily or
frequent cycling. An equalizing charge should be given
if any of the following conditions exist:
1. The specific gravity of any cell at the end of charge
is 20 points less than the average.
2. The on-charge voltage of any cell at the end of
charge is 20 MV less than the average.
3. The battery has been stored for 30 days.
4. A large volume of water has been added.
When the equalize mode is desired, follow the
operation outlined for a normal charge and press
EC2000 “Equalize” key to set the charge control for an
Additional 3 hours more than required for a normal
charge. The charge is complete when charge control
automatically lights the “Charge Complete” LED.
NOTE: The EC2000 is shipped from the
factory set to the Auto Equalize by Cycle
mode, and will automatically provide an
equalize charge every 5 complete cycles.
Manual Stop
To stop any charge cycle before charge complete,
press the “Stop” key.
WARNING: Do not connect a
battery to this charger if any
lamp is lit. Do not disconnect
a battery from this charger
while a charge is in progress.
Otherwise, damage to charger,
arcing and burning of connector
parts or a battery explosion may
result. Batteries produce
explosive gases. Keep sparks,
flame, and cigarettes away.
Ventilate when charging in an
enclosed area. Always shield
eyes when working near
batteries.
AC Power Fail
The EC2000 Control will resume the charge where it
left off when the AC power failure occurred, virtually
unaffecting charge time.
As power is returned, if a charge cycle was in progress,
the display may show “ACFAIL RESTART”. The
charger is staggering the restart based on cycle run
times. This will prevent multiple chargers from restart-
ing all at once, minimizing peak restart power.
NOTE: If a battery is disconnected from the
charger during an AC power failure and
discharged, reconnecting it or any other
battery may result in an incomplete charge
cycle.
WARNING: ELECTRICAL
SHOCK HAZARD – Before
checking electrical
components, turn off and
remove fuses of disconnect
switch (supplying AC power
to charger) and disconnect
battery.
Abnormal Shutdowns
1. Manual Stop
If the manual stop key is pressed during the charge
cycle, the charger will shutdown. All 4 LEDS will be
flashing and the display will read “Manual Stop
Fault”.
2. Back-Up Timer Shutdown
The standard EC2000 Control has two back-up
timers. The charger will shutdown and “Backup
timer” will be displayed if 9* hours has passed
since the start of a charge cycle and the battery
has not reached gassing voltage (80% charged), or
if 4 hours has passed since the battery has
reached gassing voltage and a DV/DT charge ter-
mination has not occurred.
*5 hours when in opportunity charge mode.
3. Battery Disconnect Shutdown
If a battery is disconnected from the charger during
a charge cycle, the charger will be shut down. All
LEDS will be off.

4. Low Current Shutdown
If the charger output falls below a predetermined
level, a low current shutdown will occur. All 4
LEDS will be flashing and the display will read “Low
Current Fault”.
5. Curve Error Shutdown
If the charger output becomes uncontrolled and
falls above or below the proper level for predeter-
mined period of time, the charger will shutdown.
All 4 LEDS will be flashing and the display will read
“Curve Error Fault”.
6. Overtemperature Shutdown
If the charger internal temperature exceeds a
predetermined limit, the charger will shut down.
All 4 LEDS will be flashing and the display will
read “Overtemperature”.
7. Didt Shutdown
After the 80% charged point, if the output current
begins to rise for more than a predetermined time
period, the charger will be shutdown. All 4 LEDS
will be flashing and the display will read “Didt
Fault”.
8. Low Voltage Shutdown
If a battery on charge does not reach a minimum
on charge voltage in a predetermined period of
time, the charger will be shutdown. All 4 LEDS will
be flashing and the display will read “Low Voltage
Fault”.
9. High Amp Hour Returned Shutdown
If the cycle amp hours returned exceed the BID AH
setting or charger maximum AH rating for a prede-
termined amount, the charger will shutdown. All 4
LEDS will be flashing and the display will read
“High Amp Hour Fault”.
10. Phase Error Shutdown
If the charger control detects a problem with the
unit’s input power, the charger will shutdown.
All 4 LEDS will be flashing and the display will read
“Phase Error”.
