INTRODUCING... THE SP SERIES C-CHARGER

Thank you for purchasing the SP SERIES C-CHARGER. Your SP series C-Charger represents the latest in

electronic, pulse-modulated switching chargers. The SP series C-Chargers incorporate Charles Industries’ new

battery selector switch that allows the use of currently available battery types (lead acid, gel cell and AGM). It is

designed for hard-wired, on-board applications only. The SP series C-Charger converts AC shore power to DC

charging current to maintain a selected battery type at 12 volts. The SP series models charge up to three battery

banks simultaneously. All of the SP series C-Charger units operate under a wide range of input voltages yet main-

tain a constant output, avoiding any danger of overcharging marine batteries. When necessary, the SP series

units are equipped with a cooling fan and an internal temperature compensation circuit that automatically adjusts

to temperature variations, extending the life of the batteries.

ger, Troubleshooting the SP series C-Charger and Warranty & Customer Service.

Maintenance/Cleaning Precaution

To reduce the risk of electrical shock, disconnect the SP series C-Charger from AC power before attempting any

maintenance or cleaning.

Personal Safety Precautions:

Adhere to the following personal safety precautions when installing or working with any SP series C-Charger:

1. Someone should be within voice range or close enough to come to your aid when you work near a

lead acid battery.

2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

3. Wear complete eye protection and clothing protection. Avoid touching eyes while working near a bat-

tery.

4. If battery acid contacts skin or clothing, wash them immediately with soap and water. If acid enters

the eye, flood the eye with cold, running water for at least ten minutes and get medical attention im-

mediately.

5. Never smoke or allow a spark or flame in the vicinity of the battery or engine.

6. Do not drop a metal tool onto the battery. It might spark or short circuit the battery or other electrical

parts that may cause an explosion.

7. Remove all personal metal items such as rings, bracelets, necklaces and watches when working near

a lead acid battery. A battery can produce short circuit currents high enough to weld a ring or the like

to metal, causing a severe burn.

8. The SP series C-Charger is not intended to supply power to a low voltage electrical system other

than in a marine application. Do not use the SP series C-Charger for charging dry cell batteries that

are commonly used with home appliances. These batteries may burst and cause personal injury and

property damage.

9. NEVER charge a frozen battery.

LT-2000SP-1

Issue 1 Print 2

Preparing to Charge Precautions

To reduce risk of injury, refer to Figure 3 to insure that the proper cell type is selected. DO NOT

attempt to charge multiple or non-recommended cell types. Other types of batteries may burst,

causing personal injury and damage. When changing from one cell type to another, refer to Figure 3

to select the proper battery type.

CAUTION

Before charging a battery with the SP series C-Charger, read the following precautions:

1. If the battery must be removed from the boat, always remove the grounded terminal from the battery

first.

Note: When removing the battery from the boat make sure all accessories in the boat are off.

2. Be sure the area around the battery is well ventilated while the battery is being charged. Gas can be

forcefully blown away using a piece of cardboard or other non-metallic material as a “hand fan”.

3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.

4. Add distilled water in each cell until battery acid reaches levels specified by the battery manufacturer.

This helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, carefully

follow the manufacturer’s recharging instructions.

5. Study all battery manufacturer’s precautions, such as removing or not removing cell caps while

charging and recommended rates of charge.

Connecting to the Battery Outside the Boat Precautions

SP series C-Chargers have been specifically designed for hard-wired marine use inside a boat. They are not de-

signed or equipped for charging batteries on shore or outside a boat.

Grounding Precautions

When the SP series C-Charger is permanently mounted inside the boat, it must have a grounding conductor.

1. The SP series C-Charger should be connected to a metal, grounded, permanent wiring system. An

equipment-grounding conductor should be run with the circuit wiring and connected through the SP

series C-Charger housing grommets to the equipment grounding (GND) terminal on the SP series

C-Charger.

2. Connections to the SP series C-Charger should comply with all local codes and ordinances.

INSTALLING THE SP SERIES C-CHARGER

Verifying Proper Battery/Charger Type

SP series C-Charger models may be used for charging LEAD ACID (wet/flooded), GEL CELL (gelled electrolyte)

or AGM (absorbed glass mat) batteries. All SP series C-Chargers have been factory preset for GEL CELL batter-

ies. To change the battery type of the SP series C-Charger model, refer to Figure 3.

Choosing Mounting Location

The SP series C-Charger should be mounted vertically flush on a bulkhead in a protected area away from rain or

spray, and be as close to the batteries as possible. The SP series C-Charger is designed to operate in high ambi-

ent temperatures, with the proper ventilation. Six inches of unobstructed area on all sides of the unit should be

allowed for air circulation and cooling.

Note: When necessary, the SP series C-Chargers are equipped with cooling fans. The fans will start operation

when the load is approximately 50% of the maximum rated output current. When a cooling fan is

installed, a temperature compensation circuit automatically adjusts to room temperature variations. A

LT-2000SP-1

Issue 1 Print 2

temperature coefficient of 0.02VDC/C causes the output voltage of the SP series C-Charger to change

inversely with the change in room temperature. The purpose of this circuit is to extend the life of the bat-

teries.

Choosing Mounting Hardware

As with any marine equipment, secure mounting is of utmost importance. The bolts or screws used to secure the

SP series C-Charger must be 1/4 inch diameter, backed with a flat washer, and kept vibration-free with a split-ring

lock washer. If using bolts, they must be long enough to be secured on both sides of the bulkhead. If using

screws, they should be at least 1-inch long. All hardware should be corrosion-resistant.

Mounting the SP Series C-Charger

All corrosion-resistant mounting hardware should be readily available. Follow the steps below to mount the SP

series C-Charger to the bulkhead.

Step Action

1. Mark the mounting holes.

2. Remove the unit and drill the mounting holes.

3. Insert one side of the mounting hardware half-way into the drilled mounting holes.

4. Align the mounting slots on the SP series C-Charger with the inserted hardware and slide the SP series

C-Charger’s mounting flange under the washers.

5. Insert the mounting hardware for the other side.

6. Secure all mounting hardware.

Mounting the Optional Splash Guard

Step Action

1. Position and install the optional splash guard over the SP series C-Charger so that the back flange bot-

tom rests on top of the SP series C-Charger. This ensures proper vertical spacing for ventilation. For

optimum splash protection, be sure to center the splash guard horizontally over the SP series C-Char-

ger.

2. Secure with 1/4 inch diameter screws.

Choosing Electrical Wiring Hardware

The SP series C-Charger is intended for hard-wiring in a permanent application. Conduit or other appropriate ma-

rine electrical installation hardware should be used.

Note: Do not wire any additional AC and/or DC operated products and/or cables to the charger

Choosing Wire Gauge

Use Table 2 to determine the appropriate wire gauges. Avoid unnecessarily long runs of either AC or DC power

lines.

Before working on electrical equipment, first determine there is no live power. Double check power

connections and all battery terminations.

DANGER

Connections to the SP series C-Charger shall comply with the U.S. Coast Guard Electrical Regulations

(33CFR183 subpart I).

Installing External Fuse (not supplied)

In accordance with ABYC E-11, a fuse or circuit breaker must be placed within 7 inches of the battery on all

positive conductors, or within 72 inches of the battery if the entire cable length is enclosed in a conduit.

Also see Coast Guard Reg. 33CFR183, subpart I.

WARNING

Fuses and/or circuit breakers must be sized 120 to 150% of the unit’s output amperage (Table 1), but no greater

than 150% of the rating of the conductor.

Replacing the Cover

Before replacing the cover, make sure that all electrical connections have been properly made at all the battery

banks (most important) and at the SP series C-Charger. Also check that all wiring is properly dressed with no ex-

posed, bare wires.

Applying Power

Step Action

1. Apply shore power to the unit and turn on the AC power source circuit breaker.

2. Check the front-panel ammeter for movement. A substantial movement in a clockwise direction indi-

cates the batteries need a charge (there should be a slight movement even if the batteries are

charged). If a counterclockwise movement occurs, turn off power immediately and refer to Table 4.

If the SP series C-Charger does not charge batteries or perform as described, refer to the section in this manual

on Troubleshooting the SP Series C-Charger.

OPERATING THE SP SERIES C-CHARGER

Always follow all precautions in the section on Important Safety Instructions in this manual.

Proper Operation

When properly installed and connected, the SP series C-Charger will automatically charge and maintain the bat-

teries. When power is applied, the SP series C-Charger will enter a bulk or “quick-charge” mode, during which a

higher rate of charge is achieved to replenish the batteries. After four (4) hours in the quick-charge mode, the out-

put will drop to a float rate to maintain the batteries at the selected finishing voltage (refer to the charge voltages

in Table 3).

Table 3. Charge Voltages

CHARGE VOLTAGE (BULK) CHARGE VOLTAGE (FLOAT) BATTERY TYPE

14.5V Lead Acid (Wet/Flooded) 13.6V

14.2V Gel Cell (Gelled Electrolyte) 13.6V

14.2V AGM (Absorbed Glass Mat) 13.4V

Changing Internal Fuses

Irregular conditions or loads may cause one or both of the internal fuses to blow. ALWAYS determine there is no

live power before replacing a fuse.

Step Action

1. Open the cover as described in the Making AC Connections section.

2. The AC fuse (F1) is located just above the AC terminal block (TB1) and the DC fuse (F2) is located to

the right of the DC terminal block (TB2) (see Figures 1 or 2). When replacing fuses, use only fuses of

the exact type and rating (see Table 1).

3. Before reapplying power, replace and secure the cover.

As the batteries charge, the ammeter gradually falls. When it reads zero, the

batteries are fully charged.

2. It takes too long to

charge batteries.

The SP series C-Charger brings a discharged battery voltage level up slowly to

avoid shortening the life of the battery. The recharge time depends on the de-

gree of discharge.

3. Unable to identify if

lack of battery charge

is due to a battery

problem or a SP se-

ries C-Charger prob-

lem.

When the ammeter reads zero, test the condition of a battery by first turning off

the AC power source to the SP series C-Charger, and disconnecting the battery

from the SP series C-Charger for at least one hour. Connect battery to an ohm-

volt meter. A reading of 12.6 VDC or more is desirable. A reading between 12.4

and 12.6 indicates a charge between 75 and 100%. A reading between 12.2 and

12.4 VDC indicates a charge between 50 and 75%. Consult the battery manufac-

turer’s specifications and instructions.

If it appears the battery is operating properly, proceed to check the following only

after reading and fully understanding all safety instructions listed in this manual.

Check input voltage at 120 VAC, check the SP series C-Charger’s AC fuse and

DC fuses, check the battery fuse/AC circuit breaker (Figures 1, 2 or 3, Note 3)

and check all associated wiring connections. If these appear to be working, the

SP series C-Charger’s DC output can be tested by turning off all AC power to

the unit and then disconnecting all DC outputs from the charger. Upon reapplying

AC power, the DC voltage between any DC (+) and DC (−) output terminal on

TB2 should be between 13.5 and 15 volts DC. Should the unit still be inoperable

after all tests have been completed in sequence, refer to the section in this

manual on Warranty & Customer Service.

4. The ammeter deflects

in a counterclockwise

direction.

Disconnect the unit immediately. Examine wiring instructions again to assure

proper connections. A movement in a counter-clockwise direction or a full-scale

movement indicates excessive current. A wiring error is suspected. A voltmeter

can monitor the voltage at the battery when the SP series C-Charger is turned

on. An increase in voltage should occur as power is applied.

5. The internal red LED

is on.

The unit is at half power because the ambient air is too hot. The unit may be at

half power because the fans are not working. Full power will be restored when

the temperature returns to normal.
