B. PERSONAL PRECAUTIONS AND SAFETY
1. Wear complete eye protection and clothing protection when
working with lead-acid batteries.
2. Make sure someone is within range of your voice or close
enough to come to your aid when you work with or near a
lead-acid battery.
3. Have plenty of fresh water and soap nearby for use if battery
acid contacts skin, clothing, or eyes. If battery acid contacts
skin or clothing, wash immediately with soap and water.
4. Avoid touching your eyes while working with a battery. Acid
particles (corrosion) may get into your eyes! If acid enters
your eye, immediately flood eye with running cold water for
at least 10 minutes. Get medical attention immediately.
5. Remove all personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid
battery. A lead-acid battery can produce a short-circuit current
high enough to weld a ring (or the like) to metal, causing a
severe burn.
6. Take care not to drop a metal tool or other metal onto the
battery. Metal may cause sparking or short circuit the battery
or another electrical device. Sparking may cause an explosion.
7. Always operate battery charger in an open, well- ventilated
area.
8. NEVER smoke or allow a spark or flame in the vicinity of the
battery or engine. Batteries generate explosive gases.
9. NEVER charge a frozen battery.
WARNING: EXTERNAL CONNECTIONS TO CHARGER SHALL
COMPLY WITH THE UNITED STATES COAST GUARD ELEC-
TRICAL REGULATIONS (33CFR183, SUB PART1).
C. PREPARING TO CHARGE
1. If necessary to remove battery from boat or vehicle to charge,
always remove grounded terminal from battery first. Make
sure all accessories in the boat or vehicle are off, so as not
to cause an arc.
2. Clean battery terminals. Take care to keep corrosion from
coming in contact with your eyes.
3. If required, add distilled water in each cell until battery acid
reaches levels specified by battery manufacturer. This helps
purge excess gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturer’s recharging
instructions.
4. Study all battery manufacturers’ specific precautions, such
as removing or not removing cell caps while charging, and
recommended rates of charge.
5. Be sure area around battery is well ventilated while battery is
being charged. Using a piece of cardboard or other non-
metallic material as a fan can forcefully blow gas away.
NOTE: Not for use with “eye” type batteries.
D. CHARGER LOCATION
For best operation, the charger should be mounted vertically to
the bulkhead. If the unit must be mounted horizontally, do not
restrict the airflow under the charger. Do not mount the charger
next to fuel tanks or below the waterline of the boat. The charger
is waterproof and is approved for mounting on the weatherdeck.
To allow for proper air circulation, a minimum of four inches of
unobstructed area must be permitted on all sides of the charger.
The charger is equipped with an internal thermocouple. Choos-
ing a location that will have the same surrounding temperature
as the battery(ies) is ideal and will allow for the charger to com-
pensate the current according to the initial temperature.
Chose a location such that the six-foot cables can reach the
battery(ies). If extra length is needed, bring the ring lugs to a
terminal block and extend with a minimum of 14AWG cables.
Choose larger wire for extended runs.
The charger weight is substantial. Ensure that the mounting sur-
face is strong enough to support the charger. Choose a location
that will allow for all six mounting holes to be used. Mounting
with nuts, bolts and lock washers is preferable to screws.
Never place the charger directly above the battery being charged;
gases may harm the charger over time. Never allow acid to drip
on the charger when reading specific gravity or filling battery.
Do not set a battery or any other object on top of charger.
E. MOUNTING INSTRUCTIONS
The charger may be permanently mounted and connected. Six
mounting holes have been provided for secure installation. Choose
a location for the charger (see “CHARGER LOCATION” for proper
placement). Using the charger as a template, place the charger
in the selected location and mark each of the six holes with a
pencil. In a well ventilated environment, drill the six holes using a
#9 (7/32”) drill bit for use with nuts and bolts OR with a 5/32” drill
bit for use with #10 self tapping screws. Take caution of the area
on the other side that you are drilling to avoid drilling into wires or
other components. Using #10 bolts, nuts and lockwashers, mount
the charger with the LEDs facing up on a flat vertical surface to
allow for ventilation. Route the AC and DC cords to either end
and avoid pinching them under the base. A sealant may be used
to waterproof the screw holes.
NOTE: Mounting the charger horizontally may not allow excess
heat to rise away from the charger; if the charger must be mounted
horizontally, take care to ensure there is a four inch minimum
clearance around all sides of charger to provide adequate venti-
lation.
NOTE: This charger has an internal thermocouple. If the unit gets
too hot, the current will be reduced to allow the charger to cool to
normal operating temperatures and restart. If the unit does not
cool, the charger will temporarily shut off until normal tempera-
tures are obtained.
