UniCharge 50
Automatic Battery Charger
IMPORTANT SAFETY
INSTRUCTIONS
SAVE THESE INSTRUCTIONS
1.
This manual contains important safety and operating
instructions for battery charger types UniCharge 50.
2.
Do not expose charger to rain or snow.
3.
This charger is suitable for commercial use only and is
to be permanently installed and hard-wired within
an enclosure.
4.
Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of
fire, electric shock, or injury to persons.
5.
Do not over-tighten field wiring terminals. Observe the
recommended tightening torque of 0.5Nm
(4.5 pound/inch).
6.
Do not operate charger with damaged connections
replace faulty external wiring immediately.
7.
Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way;
Take it to a qualified serviceman or return it to the
manufacturer.
8.
Do not disassemble charger; take it to a qualified
serviceman or return it to the manufacturer when
service or repair is required. Incorrect reassembly may
result in a risk of electric shock or fire.
9.
To reduce risk of electric shock, unplug charger from
outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.
10. WARNING – RISK OF EXPLOSIVE GASES.
a)
WORKING IN VICINITY OF A LEAD-ACID
BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT
YOU FOLLOW THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.
b) To reduce risk of battery explosion, follow these
instructions and those published by battery
manufacturer and manufacturer of any equipment
you intend to use in vicinity of battery. Review
cautionary marking on these products.
11. PERSONAL PRECAUTIONS
a) Consider having someone close enough by to
come to your aid when you work near a lead-acid
battery.
b) Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or eyes.
c) Wear complete eye protection and clothing
protection. 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 flood eye with running cold water for at
least 10 minutes and get medical attention
immediately.
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 battery or other electrical part that may
cause explosion.
g) Remove 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.
h) Use charger for charging LEAD-ACID, SEALED
LEAD ACID (VRLA) or GEL type batteries only.
DO NOT use battery charger for charging dry-cell
batteries that are commonly used with home
appliances. These batteries may burst and cause
injury to persons and damage to property.
i) NEVER charge a frozen battery.
12. PREPARING TO CHARGE
a) Be sure area around battery is well ventilated while
battery is being charged.
b) Clean battery terminals. Be careful to keep
corrosion from coming in contact with eyes.
c) Add distilled water in each cell until battery acid
reaches level specified by battery manufacturer.
Do not overfill. For a battery without removable cell
caps, such as valve regulated lead acid batteries,
carefully follow manufacturer’s recharging
instructions.
d) Study all battery manufacturer’s specific
precautions while charging and recommended
rates of charge.
e) Determine voltage of battery by referring to battery
manufacturers manual and make sure that the
battery chargers output voltage is set at the correct
voltage.
13. CHARGER LOCATION
a) Install the charger in an enclosure separated from
the battery.
b) Mount the unit on a flat surface in any orientation
c) Use pre-drilled holes, press-fit nuts or drill mounting
holes to suit. Use M4 or equivalent machine screws
with suitable nuts and vibration-proof washers.
DO NOT over tighten fixing screws.
d) Ensure adequate ventilation within enclosure.
Do not operate charger in a closed-in area or
restrict ventilation in any way. Leave at least 15mm
of space on all sides for adequate heat dispersion
and free air convection.
e) Never place charger directly above battery being
charged; gases from battery will corrode and
damage charger.
f) Never allow battery acid to drip on charger when
reading electrolyte specific gravity or filling battery.
g) Do not set a battery on top of charger.
14. DC CONNECTION PRECAUTIONS
a) This charger is suitable for commercial use only
and is to be permanently installed and hard-wired
within an enclosure.
b) Use tri-rated cable of at least 16 AWG (1.5mm2
cross-sectional area) for dc output connections.
Recommended cable type is UL style 1015 or
