Preparing To Charge; Ground/Ac Power Cord Connections - Schumacher DY-1420 Owner's Manual

B.
1. WARNING: 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

Charger should be grounded to reduce the risk of electric shock.
Charger is equipped with an electric cord having an equipment grounding
conductor and 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. This battery charger is designed for use on a nominal 120
volt circuit and has a grounded plug that looks like the plug illustrated in
FIGURE 1 (A). This plug should be used in a grounded outlet. The plug
pins must fit the receptacle (outlet).
ADAPTER: A temporary adapter, as shown in FIGURE 1 (B) and (C), may
be used to connect the charger plug to a two pole receptacle (outlet), as
shown in FIGURE 1 (B).
NOTE: The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
DANGER: Never alter the AC cord or plug provided. If it will not fit outlet, have a proper outlet installed by a qualified electrician. Improper connection can
result in a risk of an electrical shock. DANGER: Before using an adapter, as illustrated, be certain that the center screw of the outlet plate is grounded.
The green-colored rigid ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If neces-
sary, replace original outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet cover plate and make ground connection to
grounded outlet.
D.
1. Make sure you have a 12 volt lead-acid battery and select
appropriate battery charger switch.
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 excessive gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturer's recharging
instructions.
4. Study all battery manufacturer's specific precautions, such
as removing or not removing cell caps while charging, and
recommended rates of charge.
E.
Never place charger directly above the battery being charged,
gases from battery could damage the charger.
Never allow battery acid to drip on the charger when reading
specific gravity of filling battery.

PREPARING TO CHARGE

CHARGER LOCATION PRECAUTIONS
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 devise. 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!
FIGURE 1 GROUNDING METHODS
5. Be sure area around battery is well ventilated while battery is
being charged. Gas can be forcefully blown away by using a
piece of cardboard or other non-metallic material as a fan.
6. If necessary to remove battery from vehicle to charge, always
remove grounded terminal from battery first. Make sure all
accessories in the vehicle are off, so as not to cause an
arc.
7. A marine (boat) battery must be removed and charged on
shore. To charge it on board requires equipment specially
designed for marine use.
Never operate charger in a closed in area, or restrict ventila-
tion in any way.
Do not set battery on top of the charger.
