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.
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.
WARNING
MISE EN GARDE
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 @ 25
C 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.
