Before charging a battery with the 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.

INSTALLING THE C-CHARGER

Verifying Proper Battery/Charger Type

C-Charger models may be used for charging LEAD ACID (wet/flooded) or GEL CELL (sealed recombinant) bat-
teries. Confirm the intended battery type with the model number on the product identification label located on the
C-Charger (refer to Table 1). All C-Chargers have been factory preset. If your C-Charger model does not match
your intended battery type, contact Charles Marine Customer Service at 847/806-6300 for further assistance.
Choosing Mounting Location
The 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 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 allowed for air circulation
and cooling.
Note: The 40-, 50- and 60-amp 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 temperature compensation
circuit exists to automatically adjust to room temperature variations. A temperature coefficient of
−0.04VDC/C causes the output voltage of the C-Charger to change inversely with the change in room
temperature. The purpose of this circuit 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
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 C-Charger
All corrosion-resistant mounting hardware should be readily available. Follow the steps below to mount the C-
Charger to the bulkhead.
Step Action
1. Hold the C-Charger vertically flush on the bulkhead
2. Mark the mounting holes
3. Remove the 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 C-Charger with the secured hardware and slide the C-Charger’s mount-
ing flange under the washers
7. Insert the mounting hardware for the other side
8. Secure all mounting hardware.

Mounting the Splash Guard

Position and install the splash guard (Figure 1) over the C-Charger so that the back flange bottom rests on top of
the C-Charger. This insures proper vertical spacing for ventilation. For optimum splash protection, be sure to cen-
ter the splash guard horizontally over the C-Charger. Secure with 1/4-inch diameter screws, approximately 1/2
inch long.
Choosing Electrical Wiring Hardware
The C-Charger is intended for hard-wiring in a permanent application. Conduit or other appropriate marine electri-
cal installation hardware should be used.

Making DC Connections on Terminal Block 2 (TB2)

After the appropriate wire lengths and gauges have been determined, make the DC connections to TB2. (Route
the DC wire through the right-side access hole on the bottom of the C-Charger.) TB2 has three positive (+) termi-
nals for up to three battery banks. One negative (−) terminal is provided that is common for all battery banks.
WARNING
In accordance with ABYC E-11, a fuse or circuit breaker must be placed within 72-inches of the point of
connection to the batteries or its buss on all positive output conductors. Also see Coast Guard Reg.
33CFR183 subpart I.

French MISE EN GARDE Français

Selon la norme américaine ABYC E-11, un fusible ou un disjoncteur doit être placé à moins de 1,8 m
(72 po) du point de branchement des batteries ou de ses bus sur tous les conducteurs de sortie
positifs. Consultez les réglementations de la garde côtière américaine (no 33CFR183 section I).

Installing External Fuse (not supplied)

A fuse or circuit breaker (not provided) must be installed within 72-inches of the C-Charger on each positive (+)
DC output wire that is connected to a battery bank. Use a 60-amp fuse for 40-amp models and an 80-amp fuse
for 50- and 60-amp models. See Figure 1 Note 3 for the location of this external fuse or circuit breaker.
Note: The C-Charger comes equipped with three internal fuses: F1, F2 and F3. F1 is either a 12A slow-blow
input fuse for the 40-amp model or a 15A slow-blow input fuse for the 50- and 60-amp models. F2 and F3
are 30A fast-acting output fuses for the 40-amp model or 40A fast-acting output fuse for the 50- and
60-amp models.

Closing the Access Door

Before closing the access door, make sure that all electrical connections have been properly made at all the bat-
tery banks (most important) and at the C-Charger. Also check that all wiring is properly dressed with no exposed,
bare wires. Pull down the C-Charger access door and secure it to the top cover with the small screw provided.
Applying Power
Apply shore power to the unit and turn on the AC power source circuit breaker. Check the front-panel ammeter for
movement. A substantial movement in a clockwise direction indicates the batteries need a charge (there should
be a slight movement even if the batteries are charged). If a counter-clockwise movement occurs, turn off power
immediately and refer to Table 5.
If the C-Charger does not charge batteries or perform as described, refer to the section in this manual on Trouble-
shooting the C-Charger.

OPERATING THE C-CHARGER

Always follow all precautions in the IMPORTANT SAFETY INSTRUCTIONS section in this manual.
Proper Operation
When properly installed and connected, the C-Charger will automatically charge and maintain the batteries. When
power is applied, the 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 output 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 (13.65 VDC @ 25C for lead
acid).
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. To access the fuses, remove the small screw in the center of the unit that se-
cures the sliding door to the top cover. Slide the access door up until it stops. The AC fuse (F1) is located just
above the AC terminal block (TB1) and the DC fuse (F2) is located above the DC terminal block (TB2). When
replacing fuses, use only fuses of the exact type and rating (See Table 4). Before reapplying power, pull down the
access door to close it. Once down, secure the access door to the top cover with the small screw provided.

MAINTAINING THE C-CHARGER

There are no adjustment or maintenance requirements for the C-Charger other than cleaning the outside 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.
CAUTION
Check battery water levels frequently, especially if the boat is at dock for extended periods of time.
Low water levels will damage batteries!

French ATTENTION Français

Vérifiez fréquemment le niveau des liquides de la batterie, surtout si l’embarcation demeure à quai
pendant de longues périodes. Des niveaux trop bas peuvent endommager les batteries.

TROUBLESHOOTING THE C-CHARGER

If there is a problem with the C-Charger, first check all connections and retest. If all connections are good, see if
the problem is covered in Table 5. If the problem is not covered in Table 5, or if the C-Charger still malfunctions
after performing the solution given, contact Charles Marine Products for technical assistance.

Consult the battery manufacturer’s Owner’s Manual for 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 C-Charger’s AC fuse and DC fuse, check the battery
fuse/AC circuit breaker (Figure 1, Note 3) and check all associated wiring connections.
If these appear to be working, the 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 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.
