k) BOAT BATTERIES MUST BE REMOVED AND CHARGED ON SHORE. TO SAFELY CHARGE THEM
ON BOARD REQUIRES EQUIPMENT ESPECIALLY DESIGNED AND UL/CE LISTED FOR MARINE USE.
l) Do not overcharge battery. See Safety Instructions (3)
m) Connect and disconnect battery leads only when AC supply cord is disconnected.
n) When charging a battery, locate in a dry, well-ventilated area.
o) Never place articles on or around PROFI CHARGER, or locate PROFI CHARGER in a way that will restrict
the flow of cooling air through cabinet
p) An extension cord should not be used unless absolutely necessary.
q) Have damaged cord or plug replaced immediately only by a qualified service center to prevent risk of
electric shock or fire.
r) Do not expose PROFI CHARGER to wet weather conditions.
2.2 Personal precautions
a) Always have someone within range of your voice, or close enough to come to your aid, when working
around batteries.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
c) Wear complete eye protection, clothing protection, and wear rubber soled shoes. Place damp cloth over
battery to protect against acid spray. When ground is very wet or covered with snow, wear rubber boots.
Avoid touching eyes while working near battery.
d) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately
flush with running cold water for at least 10 minutes and get doctor’s attention.
e) NEVER smoke or allow a spark or flame in vicinity of battery or engine.
f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short circuit the
battery or other electrical part that may cause an explosion.
g) Before working with a battery, remove personal metal items such as rings, bracelets, necklaces, watches,
etc. A battery can produce a short circuit current high enough to weld such items causing a severe burn.
h) Use charger for charging LEAD ACID batteries only. The PROFI CHARGER is not intended to supply power
to a low-voltage electrical system other than applications using rechargeable type batteries. Do not use
battery charger for charging dry-cell batteries commonly used with home appliances. These batteries may
burst and cause personal injury and property damage.
i) NEVER charge a frozen battery, thaw it out first. Charging will then be safer and more efficient.
2.3 Preparing the Battery
a) 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.
b) Use stud adapters on side-post and/or Truck batteries that are not in the vehicle.
c) Be sure area around battery is well ventilated while battery is being charged. Using a piece of cardboard
or other nonmetallic material as a fan can forcefully blow gas away.
d) Clean battery terminals. Be careful to keep corrosion from coming into contact with your eyes.
e) Add distilled water in each cell until battery acid reaches level specified by manufacturer. This helps
purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow the manufacturer’s
recharging instructions.
f) Study all battery manufacturers’ specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
g) Determine the voltage of the battery and make sure that the output voltage menu selection is set at the
correct voltage.
2.4 DC Connection precautions
a) Set the PROFI CHARGER switch in the OFF position and AC cord should be DISCONNECTED from
electrical outlet before you connect and disconnect PROFI CHARGER clamps. Never allow clamps
to touch each other.
b) When attaching PROFI CHARGER clamps, be certain to make the best possible mechanical as well as
electrical connection. Clamps should be kept clean.
