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. The SP Series models charge up to three battery banks si-
multaneously. All of the SP series C-Charger units operate under a wide range of input voltages yet maintain 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 tem-
perature variations, extending the life of the batteries. An external temperature compensation circuit is an avail-
able option (sold separately) on some models.
The various models available in the 5000 series C-Charger product offering are listed in Table 1.

Personal Safety Precautions
Adhere to the following personal safety precautions when installing or working with any of the 5000 SP series C-
Chargers:
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 may spark or short circuit the battery or other electrical
parts that can 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.
Preparing to Charge Precautions
CAUTION
To reduce risk of injury, refer to Figure 1 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 batteries from one cell type to another, refer to
Figure 1 to select the proper battery type on the back of the unit.
Before charging a battery with the SP series C-Charger, read the following precautions:
1. Make sure all accessories in the boat are off.
2. If the battery must be removed from the boat, always remove the grounded terminal from the battery
first.
3. 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”.
4. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
5. 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.
6. 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 Precaution
The 5000 SP series C-Chargers have been specifically designed for hard-wired marine use inside a boat. They
are not designed 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 (GRN) terminal on the SP series
C-Charger.
2. Connections to the SP series C-Charger should comply with all local codes and ordinances.
External connections to the SP series C-Charger shall comply with the U.S. Coast Guard Electrical
Regulations (33CFR183 subpart I).
WARNING
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 1.
Note: If using Odyssey batteries, the switch should be set for LEAD ACID.

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 as close to the batteries as possible. The SP series C-Charger is designed to operate in high ambient
temperatures, with the proper ventilation. Six inches of unobstructed area on all sides of the unit should be al-
lowed for air circulation and cooling.
Note: The 30-,40-, 50-, 60-, 80- and 100-amp. SP series C-Chargers are equipped with a cooling fan. The fan
will start operation when the load is approximately 50% of the maximum rated output current. Also, a tem-
perature compensation circuit exists to automatically adjust to room temperature variations. A tempera-
ture coefficient of 0.02VDC/_C for 12 volts or 0.04VDC/_C for 24 volts causes the output voltage of the
SP series C-Charger to change inversely with the change in room temperature. The purpose of this cir-
cuit is to extend the life of the batteries.
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 in 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. Hold the SP series C-Charger vertically flush on the bulkhead.
2. Mark the mounting holes.
3. Remove the SP series C-Charger.
4. Drill the mounting holes.
5. Insert one side of the mounting hardware half-way into the drilled mounting holes.
6. Align the mounting slots on the SP series C-Charger with the secured hardware and slide the SP series
C-Charger’s mounting flange under the washers.
7. Insert the mounting hardware for the other side.
8. Secure all mounting hardware.

Position and install the splash guard over the SP series C-Charger so that the back flange bottom rests on top of
the SP series C-Charger. This insures proper vertical spacing for ventilation. For optimum splash protection, be
sure to center the splash guard horizontally over the SP series C-Charger. Secure with 1/4-inch diameter screws,
approximately 1/2 inch long.
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.
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.

Installing External Fuse (not supplied)
A fuse or circuit breaker (not provided) must be installed within 7 inches of the battery on all positive (+) conduc-
tors, or within 72 inches of the battery if the entire cable length is enclosed in a conduit. Fuses/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. See figures 1, 2 or 3, Note 3 for the location of this external fuse or circuit breaker.
Closing the Cover
Before closing 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 IMPORTANT SAFETY INSTRUCTIONS section 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 “constant current” mode, during which
a higher rate of charge is achieved to fully replenish the batteries. When the batteries near a full charge, the out-
put current will decrease and the charger will enter a timed absorption mode. After four hours in absorption mode,
the output will drop to a float rate to maintain the batteries at a temperature compensated finishing voltage (13.6
VDC @ 25C for lead acid). Refer to Table 3 for charge voltages.
Table 3. Charge Voltages
Charge Voltage (bulk) Battery Type Charge Voltage (float)
14.5 volts Lead Acid (Wet/Flooded) 13.6 volts
14.2 volts Gel Cell (Gelled Electrolyte) 13.6 volts
14.2 volts AGM (Absorbed Glass Mat) 13.4 volts
Changing Internal Fuses
Irregular conditions or loads may cause one or more of the internal fuses to blow. ALWAYS determine there is no
live power before replacing a fuse.
Step Action
1. Remove the cover.
2. The AC fuse (F1) is located just above the AC terminal block (TB1) and the DC fuses (F2 and F3) are
located above the DC output connections (see Figures 1, 2 and 3). When replacing fuses, use only
fuses of exactly the same type and rating (See Table 1).
3. Replace and secure the cover.
4. Reapply power.
MAINTAINING THE SP SERIES C-CHARGER
There are no adjustment or maintenance requirements for the SP series C-Charger other than cleaning the out-
side cabinet with a dry cloth. Periodically have all connections checked by a qualified service person, especially if
the boat is operated in heavy, pounding seas.
For lead acid batteries check battery water levels frequently, especially if the boat is at dock for
extended periods of time. Low water levels will damage batteries!
CAUTION
TROUBLESHOOTING THE SP SERIES C-CHARGER
If there is a problem with the SP series C-Charger, first check all connections and retest. If all connections are
good, see if the problem is covered in Table 4. If the problem is not covered in Table 4, or if the SP series C-Char-
ger still malfunctions after performing the solution given, contact Charles Marine Products for technical assis-
tance.

Table 4. Troubleshooting Suggestions
Condition Solution
Not clear if batteries
are fully charged. As the batteries charge, the ammeter gradually falls. When it reads zero, the batteries are fully charged.
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 degree of dis-
charge.
Unable to identify if
lack of battery charge
is due to a battery
problem or an 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 be-
tween 50 and 75%. Consult the battery manufacturer’s Owner’s Manual for instruc-
tions.
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 fuse, check the
battery fuse/AC circuit breaker (Figure 1, Note 3) and check all associated wiring con-
nections. 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 (+) and (−)
output connection should be between 13.5 and 15 VDC. Should the unit still be inoper-
able after all tests have been completed in sequence, refer to the section in this manual
on Warranty & Customer Service.
The ammeter deflects
in a counterclockwise
direction.
Disconnect the unit immediately. Examine wiring instructions again to assure proper
connections. A movement in a counterclockwise direction or a full-scale movement indi-
cates excessive current. A wiring error is suspected. A voltmeter can monitor the volt-
age at the battery when the SP series C-Charger is turned on. An increase in voltage
should occur as power is applied.
Internal red LED 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 tempera-
ture returns to normal.
