When charging battery(ies) in boat, take care to determine the battery type and which pole is ground. To reduce risk of a spark near

battery, follow these general steps when battery is inside boat. 

WARNING: A spark near the battery may cause battery explosion.

1.  Position AC power cord and DC charging cords to reduce risk

of damage.

2.  Stay clear of fan blades, belts, pulleys, and other parts that 

can cause injury.

3.  Check polarity of battery posts. Battery case will be marked

to indicate each post’s polarity: POSITIVE (POS, P, +) and

NEGATIVE  (NEG,  N,  -).

NOTE:  The  positive  battery  post 

usually has a larger diameter than the negative post.

4.  Determine which post of battery is ground.

5.  Connect POSITIVE (RED) ring terminal from battery charger

to POSITIVE (POS, P, +) post of battery.

6.  Connect  NEGATIVE  (BLACK)  ring  terminal  to  NEGATIVE

(NEG, N, -) post of battery

7.  When disconnecting the charger, disconnect the AC power

cord from the electric outlet first.

8.   While disconnecting output leads from the batteries, always 

do so in reverse order of the connection procedure.

When connecting the ring terminals to the battery, remove nuts 

on battery posts, place the ring terminal on corresponding posi-

tive and negative post, and replace each nut tightly to ensure a 

good connection.
When connecting the ring terminals, connect the black 12 volt 

lead to the negative battery post and the red 12 volt lead to the 

positive battery post.

When  connecting  the  charger  to  TWO  and  THREE  batteries,

connect the positive lead from charging bank one to the positive 

post of battery one. Connect the negative lead from charging bank

one to the negative post of battery one. Connect the leads from

charging bank two to battery two, and three to battery three in the 

same fashion, . NOTE: Removal of a strap between two batteries 

in a 24 or 36 Volt system is not necessary.
FOR DETAILED WIRING – SEE DIAGRAMS BELOW

Inline fuses, located close to the ends of the red leads, protect the charger from extremely high voltage surges, lightning strikes or other 

high current surges. If a fuse blows, replace only with AGC-30 30A 32V 1 ¼” glass fuse.

Charger should be grounded to reduce risk of electric shock. Charger is equipped with an electric cord having a grounding plug. The plug

must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. 
DANGER – Never alter AC cord or plug provided – if it will not fit outlet, have proper outlet installed by a qualified electrician. Improper

connection can result in a risk of an electric shock.
CAUTION – To reduce risk of fire or electric shock, connect battery charger directly to grounding receptacle (three-prong). An adapter

should not be used with battery charger.

Connect and disconnect the DC output connections only after removing the AC cord from the electric outlet.

Once the unit has been properly connected to the battery(ies), plug in the charger to AC power. Hold the SET button for two seconds.

When the blue light turns on, press the SELECT button until the correct battery type color is blinking. Once the correct battery type is

blinking press the SET button. The blinking light will move to next battery. Green light indicates when battery(ies) is/are fully charged.
NOTE: When charging more than one battery, you will hear a clicking noise approximately every five minutes. This is normal.
