1. SAFETY INSTRUCTIONS AND WARNINGS
Before using your TOTALIFT TsMVC battery charger, please take the time to read these
instructions carefully.
The owner’s manual is an important part of the charger. It’s recommended to keep it in good
condition for the lifetime of the charger. It should be kept in a dry and clean place, always
available to the users.
To indicate important instructions, the following blocks are used throughout this manual.
GENERAL
Battery charging products can cause serious injury or death, or damage to other equipment or
property, if the operator does not strictly observe all safety rules and take precautionary
actions.
Safe practices must be learned through study and training before using this equipment.
Only qualified personnel should install, use, or service this equipment.
SHOCK PREVENTION
Bare conductors or terminals in the output circuit, or ungrounded, electrically-live equipment
can fatally shock a person. To protect against shock, have competent electrician verify that
the equipment is adequately grounded and identify what terminals and parts are electrically
HOT.
The body’s electrical resistance is decreased when wet, permitting dangerous current to flow
through the body. Do not work in a damp area without being extremely careful. Stand on dry
rubber mat or dry wood and use insulating gloves when dampness or sweat cannot be
avoided. Keep clothing dry.
INSTALLATION AND GROUNDING - A power disconnect switch must be located at the
equipment. Check the data label for voltage and phase requirements. If only 3-phase power is
available, connect single-phase equipment to ONLY TWO WIRES of the 3-phase line.
DO NOT CONNECT the equipment grounding conductor to the third live wire of the 3-phase
line as this makes the equipment frame electrically HOT, which can cause a fatal shock.
If a grounding conductor is part of the power supply cable, be sure to connect it to a properly
grounded switch box or building ground. If not part of the supply cable, use a separate
grounding conductor. Don’t remove a ground prong from any plug. Use correct mating
receptacles. Check ground for electrical continuity before using equipment. The grounding
conductor must be of a size equal to or larger than the size of the line conductors.
CHARGING LEADS – Inspect leads often for damage to the insulation. Replace or repair
cracked or worn leads immediately. Use leads having sufficient capacity to carry the operating
current without overheating.
BATTERY TERMINALS – Do not touch battery terminals while equipment is operating.
CAUTION!
This o
p
eration can be dan
g
erous for the user.
ATTENTION!
This o
p
eration is im
p
ortant for the functionalit
y
and reliabilit
y
of the char
g
er.

SERVICE AND MAINTENANCE – Shut OFF all power at the disconnect switch or line breaker
BEFORE inspecting, adjusting, or servicing the equipment. Lock switch OPEN (or remove line
fuses) so that the power cannot be turned ON accidentally.
Disconnect power to equipment if it is to be left unattended or out of service. Disconnect
battery from charger. Keep inside parts clean and dry. Dirt and/or moisture can cause
insulation failure. This failure can result in high voltage at the charger output.
BURN AND BODILY INJURY PREVENTION
The battery produces very high currents when short circuited, and will burn the skin severely
if in contact with any metal conductor that is carrying this current.
Do not permit rings on fingers to come in contact with battery terminals or the cell connectors
on top of the battery. Battery acid is very corrosive. Always wear correct eye and body
protection when near batteries.
FIRE AND EXPLOSION PREVENTION
When batteries are being recharged, they generate hydrogen gas that is explosive in certain
concentrations in air (the flammability or explosive limits are 4.1% to 72% hydrogen in air). The
spark-retarding vents help slow the rate of release of hydrogen, but the escaping hydrogen
may form an explosive atmosphere around the battery if ventilation is poor.
The ventilation system should be designed to provide an adequate amount of fresh air for the
number of batteries being charged. This is essential to prevent an explosion.
Always keep sparks, flames, burning cigarettes, and other sources of ignition away from the
battery recharging area. Do not break "live" circuits at the terminals of batteries. Do not lay
tools or anything that is metallic on top of any battery.
ARCING AND BURNING OF CONNECTOR
To prevent arcing and burning of the connector contacts, be sure the charger is OFF before
connecting or disconnecting the battery. The ammeter should NOT indicate current flow.
MEDICAL AND FIRST AID TREATMENT
First aid facilities and a qualified first aid person should be available for each shift for
immediate treatment of electrical shock victims.
EMERGENCY FIRST AID: Call physician and ambulance immediately and use First Aid
techniques recommended by the American Red Cross.
DANGER: ELECTRICAL SHOCK CAN BE FATAL.
If person is unconscious and electric shock is suspected, do not touch person if he or she is
in contact with charging equipment, battery, charging leads, or other live electrical parts.
Disconnect power at wall switch and then use First Aid.
Dry wood, wooden broom, and other insulating material can be used to move cables, if
necessary, away from person.
IF BREATHING IS DIFFICULT, give oxygen.
IF NOT BREATHING, BEGIN ARTIFICIAL BREATHING, such as mouth-to-mouth.
IF PULSE IS ABSENT, BEGIN ARTIFICIAL CIRCULATION, such as external heart massage.
In case of acid in the eyes, flush very well with clean water and obtain professional medical
attention immediately.

2. DESCRIPTION OF THE CHARGER
TOTALIFT TsMVC battery chargers have been designed to charge Lead-Acid batteries.
These units are based on a ferroresonant power transformer, with constant current output.
Two models are available:
TOTALIFT TsMVC 25: Output current 25 A
AC input 105/120 Vac – 15 A
TOTALIFT TsMVC 50: Output current 50 A
AC input 230/250 Vac – 15 A
The operation of the TOTALIFT TsMVC chargers is managed by a digital, programmable
control board of the latest generation, which includes flat membrane keyboard and LCD
display.
3. INSTALLATION OF THE CHARGER
Conditions of use:
Operating temperature: 5°C to 45°C
Storage temperature: -20°C to 60°C
Relative humidity: less than 75%
CAUTION!
Risk of electrical shock!
The charger can be installed by qualified personnel only.
To prevent fire or shock hazard, do not expose the unit to rain or moisture.
Don't use the unit in presence of flammable gas, because it can generate sparks.
ATTENTION!
Make sure that the unit's maximum input power (reported on the data label) is available from
your power supply, and verify that the unit's operating voltage is correct.
Allow adequate air circulation to prevent internal heat buildup.
Don't place the unit near heat sources such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust, mechanical vibration or shock.

The model TOTALIFT TsMVC25 is already equipped with the adequate cable and plug
AC INPUT CONNECTION
The charger must be connected to the AC input using an adequate cable and plug, with
disconnect switch and fuses.
The AC input wires have to be connected to the TERMINAL BLOCKS FOR AC INPUT CABLE,
that are located over the main transformer (see picture on the next page).
Make sure to tighten the terminal block screws with the right torque, and pull each wire
separately in order to verify that they are mounted properly.
AC INPUT VOLTAGE SETTINGS
 With reference to the following pictures, find the POWER TRANSFORMER TAPS and
the label with the list of the NOMINAL voltages available that are located on the left side
of the internal panel.
TsMVC 25 TsMVC 50
1 1x 120 VAC 1x 250 VAC
2 1x 115 VAC 1x 240 VAC
3 1x 110 VAC 1x 230 VAC
4 1x 105 VAC //
 Using an adequate AC-voltmeter, measure the value of the REAL AC input voltage
available at the mounting location of the charger.
 Identify which of the NOMINAL voltage values is closest to the REAL measured value.
ATTENTION!
The proper setting of the power transformer taps is fundamental
for the correct operation of the Totalift TsMVC chargers.
If the real AC input voltage is different than the AC nominal voltage to which the charger is set,
the charging current of the charger may be significantly different than the nominal.

Example : for a charger TsMVC 25 if the measured voltage is 117 VAC, the
transformer should be connected to the tap number 2, that corresponds to 115
VAC.

SHUTDOWN ON BATTERY DISCONNECTION
If the battery is disconnected while the charge is in progress, the TOTALIFT TsMVC charger
will return automatically to stand-by mode.
PROGRAMMING MEMORY
The TOTALIFT TsMVC has a static memory that is used to save automatically the charge
parameters programmed by the user.
This exclusive feature allows the user to program the desired charging parameters only the
first time when a battery is connected.
The next time that the TOTALIFT TsMVC is powered and a battery is connected, all the
parameters previously programmed by the user will be in memory, so the operation of the
charger is always FULLY AUTOMATIC.
End of Document -
CAUTION!
NEVER disconnect the battery while it's being charged.
Disconnecting the battery while it's being charged is hazardous
for the user and voids the charger warranty.
