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.
