IMPORTANT NOTICE

This manual contains important safety and operating instructions for the charger. Read
the entire manual before using. Also read all instructions and cautions for and on the
charger, batteries and equipment in the vicinity of the batteries.

1. INTRODUCING THE CHARGER

The Guest model 2614A, 2621A, and 2622A are designed to recharge your batteries,
and extend your battery’s life in applications where it is stored for long periods of time.
They are “3-stage” electronic, lightweight, silent, completely automatic battery chargers.
Each output produces 12 Volts DC at a full 5 Amps or 10 Amps (model specific), while
using much less AC current than other charger types. Unlike automotive “trickle”
chargers, the 2614A, 2621A, and 2622A will not boil off the electrolytes in properly
installed and maintained batteries. The red and green LED’s, mounted on the charger
face let you know the unit is recharging and maintaining your batteries. This
sophisticated device is ideal for recharging and maintaining the 12VDC batteries in
your boat, electric vehicle or cart, ATV, snowmobile or motorcycle.

WARNINGS

THIS CHARGER SHOULD BE USED TO CHARGE ONLY LEAD ACID, AGM, OR
GEL CELL TYPE BATTERIES. USE ON OTHER BATTERY TYPES MAY CAUSE
AN EXPLOSION OR PERSONAL INJURY.

RISK OF EXPLOSIVE GASES! WORKING IN THE VICINITY OF LEAD ACID
BATTERIES IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES
DURING NORMAL OPERATION. THEREFORE IT IS OF THE UTMOST
IMPORTANCE THAT EACH TIME BEFORE USING YOUR CHARGER YOU
FOLLOW THE INSTRUCTIONS EXACTLY.

Personal Safety Precautions

Adhere to the following personal safety precautions when installing or working with the
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 battery.

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.

5.

Never smoke or allow an open flame in the vicinity of the battery.

6.

Do not drop a metal tool onto the battery. It may spark, short circuit the battery and
may 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.

Preparing to Charge Precautions

Before charging a battery with the charger, read the following precautions:

1.

Do NOT operate the charger if the cables or an LED is damaged.

2.

Make sure all accessories on the product you are charging are OFF.

3.

If the battery or batteries must be removed from the product, always remove the
grounded terminal from the battery first.

4.

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”.

5.

Clean battery terminals. Be careful to keep corrosion from coming in contact with
eyes.

6.

Add distilled water in each cell until battery acid reaches levels specified by the
battery manufacturer, if applicable. Do not overfill. For all batteries, carefully follow
the manufacturer’s recharging instructions.

7.

Never allow the ring terminals to touch each other.

8.

NEVER charge a frozen battery.

9. Please be sure the DC system to which the charger is connected is not drawing excessive
current from the battery for extended periods of time while the charger is operating. This is
important to ensure the charger correctly transitions through each charging stage to finish with
the float voltage level. If the DC system is drawing continuous current while charging, reduced
life or damage to the battery may occur.

2. INSTALLING THE CHARGER

AC Connection and Grounding Precautions:

DANGER

DO NOT OPERATE THIS CHARGER WITH A TWO BLADED
ADAPTER PLUG OR EXTENSION CORD. DOING SO CAN RESULT
IN SERIOUS PERSONAL INJURY. DO NOT ATTEMPT TO WIRE
THE BATTERY CHARGER USING AN ELECTRICALLY ENERGIZED
LINE CORD. WIRE THE CHARGER ONLY WHILE THE WIRING OR
AC SOURCE IS DE-ENERGIZED. AFTER SECURING THE
BATTERY CONNECTIONS, PLUG THE AC LINE CORD INTO AN
AVAILABLE AC OUTLET THAT IS PROTECTED BY A GROUND
FAULT CIRCUIT INTERRUPTER (GFCI) BREAKER. DO NOT PLUG
INTO AC UNTIL ALL CHARGER CONNECTIONS ARE MADE.

Making AC Connections:

Reference the above drawing:

1. Make AC connections to the charger by wiring AC Hot or Line to the AC LINE

terminal, wire AC Neutral to the AC NEUT terminal, wire Earth Ground to the AC
GND terminal.

2. To interface between the conductor and the stud terminal, use either a fork or

ring terminal appropriately sized for a ¼” stud.

4

3. For 230 Vac chargers, the AC and DC wiring method is identical to 115 Vac

chargers.

Note: US Color Code is Black = Line, White = Neutral, Green or Non Insulated = Earth
Ground.
Euro color coding is Brown = Line; Blue = Neutral; Green, Green/Yellow or Non
Insulated = Earth Ground.

CAUTION: To reduce the risk of shock, connect only to a properly grounded outlet.

AC Cable size Guidelines:

For AC Cable lengths 6 feet and under use 3 conductor 18 AWG cable.
For AC Cable lengths 6 feet to 12 feet use 3 conductor 16 AWG cable
For AC Cable lengths 12 feet to 18 feet use 3 conductor 14 AWG cable

Making DC Connections:

Notes:

1. Check polarity of the battery posts. The POSITIVE (POS., P, +) battery post

usually has a larger diameter than the NEGATIVE (NEG., N, -) post.

2. Connections to the battery should be made with industry standard color coding.

Connections to the positive terminal should be made with RED wire, connections to the
negative terminal should be made with BLACK or YELLOW wire.

DC Cable size Guidelines:

Charger Output Size

10 Amp Output 2 conductor 14 AWG 2 conductor 12 AWG 2 conductor 10 AWG

5 Amp Output 2 conductor 14 AWG 2 conductor 14 AWG 2 conductor 12 AWG

Up to 6 feet 6 – 10 feet 10 – 15 feet

FOR FURTHER INFORMATION REGARDING AC AND DC WIRING STANDARDS
PLEASE SEE ABYC (AMERICAN BOAT AND YACHT COUNCIL) STANDARDS
AND TECHNICAL INFORMATION REPORTS FOR SMALL CRAFT, SECTION E-11.
