2 Crimp on ring terminals to the cable: · ring M6 for 24/50-2, 48/25; · ring
M8 for 24/75, 24/75 (120V), 24/100, 48/50, 24/50 3ph and 24/100 3ph.
3 Connect the cables to the terminals of the Mass Charger. Pay attention to
the polarity, positive on positive/negative on negative.
4 Integrate a suitable fuse (charger fuse) in the positive cable. When using a
DC distribution with fuses, no additional fuse is necessary.
5 Cut the cables to length and crimp on the ring terminals. Connect the cable
to the DC distribution or batteries. CAUTION!
Reversing the positive and negative battery poles will severely damage the
Mass Charger.
Lay the positive and negative cables next to each other to limit the
electromagnetic field around the cables. The negative cable should be
connected directly to the negative post of the battery bank or the ground side
of a current shunt. Do not use the hull or chassis frame as the negative
conductor.
3.4 Battery capacity Always follow the instructions published by the battery manufacturer.

3.5 Battery isolator If one or more batteries or battery sets must be charged
at the same time via one output, a battery isolator should be used. This
isolates the different battery sets to prevent one discharging the other.
Mastervolt offers several Battery Isolators. Please refer to
www.mastervolt.com .
A battery isolator causes a voltage drop of 0.6V. This can be compensated in
two ways:
· By changing DIP switch 4 to On (Diode enabled); · By using the voltage sense
function (see section 3.8 on
page 8);
CAUTION! Never use both methods. Your batteries will be overcharged and
severely damaged!
If you use a `voltage drop free’ battery isolator, like the Mastervolt Battery
Mate, no compensation is needed.
For a proper installation, see the connection diagram that comes with the
battery isolator.
3.6 Connection of second battery (3A output) The Mass 24/50-2 MB is standard
equipped with a second charge output which can be used to give a maintenance
charge to a small second battery set like a starter battery. The maximum
charge current of the second output is 3A, which comes from the main output.
· Use 2.5 to 4mm2 cable for the connection. · Connect the minus of the second
battery to the minus of
the main battery. · Connect the plus of the second battery to the +3A
terminal of the Mass Charger (Figure 3 and Figure 4). · Integrate a 10A slow
blow fuse in the plus cable.
3.7 Temperature sensor The standard temperature sensor is provided with 6m
cable and a double-sided tape for easy installation. 1. Make sure that the
side of the battery that you want to
place the sensor, is clean and grease-free. 2. Remove the piece of paper from
the tape and stick the
sensor on the battery. 3. Plug the modular cable into the terminal at the
right of
the Mass Charger (see Figure 3 on page 9). For the C3 enclosure (refer to
specifications) both “RS232” and “analog” are suitable. It is not necessary to
shorten the cable. When you want to shorten it anyway, please notice the
polarity of the plug and use the old connector as an example. Now when the
battery temperature is low, the charge voltage increases and when the battery
temperature is high, the charge voltage is decreased. This prevents
overcharge, and gassing, which increases the battery’s lifetime substantially.

Battery temperature (°C)
Figure 2. Temperature compensated charging
3.8 Voltage sense If required, DC cable losses can be compensated by using the
sense function. This will shorten the charge time. 1. Use 0,75mm2, preferably
red and black wire and
secure these with fuses of 2A slow blow. 2. Connect the wires with the two
upper terminals of the
green connector at the right side of the cabinet (see Figure 3 on page 9). Pay
extra attention to the polarity of the wires, red on +S and black on -S. 3.
Now connect the other side of the wires: black on the minus of the battery and
red on the plus of the battery.
3.9 Alarm function To control external equipment, the charger is equipped with
a potential free contacts alarm relay; see Figure 3 on page 9. The alarm
function has two modes: standard (factory setting) and DC alarm mode
(continuous mode). The maximum switch current of the relay is 1A. Exceeding
the setpoints will activate the alarm (see page 16).
3.9.1 Standard alarm mode In this mode the relay responds to all fault
conditions that the Mass Charger can detect such as: no AC input voltage, low
DC voltage, temperature sense failure.
3.9.2 DC alarm mode To enable this mode, a DIP switch setting needs to be
changed (switch 1 and 2 at ON). The alarm now works as a DC alarm and responds
to the battery voltage only.
Note: In the DC alarm mode the electronics stay active permanently and drain a
very small current of ±25mA, also when the Mass Charger is switched off.
3.10 RJ12 splitter for enclosure C2 The RJ12 connector (QRS232 communication
port) can be used to connect the battery temperature sensor or the remote
panel (not included). Use a RJ12-splitter to connect both at the same time
(not included).

3.15 Commissioning after installation Note: When your Mass Charger is not new,
you have to
consider that former users may have changed the settings. Reset the Mass
Charger to factory settings when there is any doubt (see section 6.3 on page
15).
3.15.1 General The factory settings of the Mass Charger are optimal for most
installations. With some applications however, it is desirable to change these
settings. Therefore, several adjustments can be made. See chapters 4 and 6.3.
Note: The DIP switches must be adjusted prior to commissioning. All other
settings can only be configured after commissioning.
CAUTION! Check the polarity of all wiring before commissioning: positive
connected to positive (red cables), negative connected to negative (black
cables).
If all wiring is OK, place the DC fuse(s) of the DC distribution to connect
the batteries to the Mass Charger.
WARNING! When placing this fuse, a spark can occur, caused by the capacitors
used in the Mass Charger.
Now the Mass Charger is ready for operation. After switching on the AC power
supply the Mass Charger will initiate the charging process.
3.15.2 MasterBus
Adjustment of the settings of the Mass Charger can be made by means of DIP
switches or via the MasterBus network (by means of an USB interface connected
to a PC with MasterAdjust software). Some settings can only be changed via the
MasterBus interface. See section 6.3 on page 15 for an overview of all
available MasterBus settings.
3.16 Decommissioning If it is necessary to put the Mass Charger out of
operation, follow the instructions in order of succession as described below:
1 Switch the Mass Charger to OFF. 2 Remove the DC fuse(s) of the DC
distribution and/or
disconnect the batteries. 3 Remove the AC fuse(s) of the AC input and/or
disconnect the AC mains. 4 Open the connection compartment of the Mass
Charger. 5 Check with a suitable voltage meter whether the inputs
and the outputs of the Mass Charger are voltage free. 6 Disconnect all wiring.
Now the Mass Charger can be demounted in a safe way.
3.17 Storage and transportation When not installed, store the Mass Charger in
the original packing, in a dry and dust free environment.
Always use the original packing for transportation. Contact your local
Mastervolt dealer for further details if you want to return the apparatus for
repair.

4 DIP SWITCH SETTINGS
The Mass Charger settings can be adjusted in two ways: · By means of DIP
switches; · Via the MasterBus network (using a remote control
panel or the Mastervolt USB interface connected to a PC with MasterAdjust
software); see chapter 6. Note: Once a DIP switch has been set to On,
MasterBus
presets are disabled but people can still change the settings!
CAUTION! Invalid settings of the Mass Charger can cause serious damage to your
batteries and/or the connected load! Adjustments of settings may be undertaken
by qualified personnel only!
4.1 DIP switch operation The Mass Charger has six DIP switches. These switches
are operated by flipping the levers to the other position, using a small
screwdriver.
Figure 5. DIP switches 4.2 DIP switch functions See the table for the
functional overview of the DIP switches (DIP switch 6 is reserved for future
use). See page 16 for an overview of charging specifications. · Force Float
(DIP switch 1)
For special applications a fixed charge voltage can be required. The battery
charger allows you to change the 3-step+ charge program to a single stage
program by activating the function “Force Float”, switching DIP switch 1 to
“ON”. The charge voltage will be fixed at 26.5V (24V charger) or 53V for a 48V
charger. · Traction setting (DIP switch 2) Setting for traction charging:
+0.7/1.4V during bulk and +0.4/0.8V in absorption for 24/48V batteries. ·
Gel/AGM batteries (DIP switch 3) Some Gel/AGM batteries need a higher float
voltage for optimal charge. Changing the float voltage can be done by setting
DIP switch 3 to “ON”. The float voltage will increase to 27.6V (24V charger)
or 55.2V for a 48V charger.
· Diode setting (DIP switch 4) Setting for +0.6V voltage compensation in case
a battery isolator is used.
· Lithium-ion setting (DIP switch 5) With firmware version 7.7.0 or higher,
the settings for charging an MLI Ultra can be selected.

5 OPERATION
5.1 Introduction The Mass charger is a fully automatic, high efficiency
battery charger/rectifier. The Mass Charger not only charges batteries rapidly
and safely, it supplies the connected consumers at the same time. In addition,
the Mass Charger is secured against short circuit, overload and high
temperatures in an industrial environment.
5.2 Switching on/off Activate the Mass Charger by switching the main switch to
the ON position. When no error is present, the charger LED illuminates green
and the Mass Charger starts charging.
Move the switch to the OFF position to switch off the Mass Charger!
5.3 The 3-step+ charge process The Mass charger is equipped with an
intelligent 3-step+ charge characteristic which takes care of an optimal
charge of your batteries. See Figure 6 and Figure 9 (page 22) for more
details.
Incorrect use of the equalize mode may lead to hazardous situations. During
equalizing the batteries are brought into the gas state and permitted load
voltages may be exceeded (refer to Figure 10 on page 23 for characteristics).
For these reasons the equalizing mode should only be used by trained technical
engineers. The equalizing mode can only be started when the Mass Charger is in
float operation. To start the equalize mode, select Equalize in the MasterBus
device settings (see section 6.3 on page 15).

The Mass Charger automatically resumes operation in Bulk stage after it was
disconnected from an AC source.
5.5 Equalize mode An equalizing charge can be necessary after very deep
discharges and/or inadequate charges. This has to be carried out according to
the specifications of the battery manufacturer.
WARNING! Equalization is ONLY applicable for flooded batteries and will damage
Gel/AGM/Spiral type batteries!

6 MASTERBUS
6.1 About MasterBus All devices that are suitable for MasterBus are marked
with the MasterBus symbol.
MasterBus is a CAN based, fully decentralized data network for communication
between Mastervolt devices. MasterBus is used as power management system for
all connected equipment, such as the inverter, battery charger, generator and
many more. Every device that is compatible with MasterBus is equipped with two
data ports. The devices are simply chained together, forming a local data
network. Monitoring panels such as the EasyView 5 can be used for monitoring
and control of all connected MasterBus equipment.
CAUTION! Never connect a non-MasterBus device to the MasterBus network
directly! This will damage all connected MasterBus devices.
6.2 How to set up a MasterBus network
· Connections between the devices are made by standard straight MasterBus
cables. Mastervolt can supply these cables.
· Up to 63 MasterBus devices can be connected together. · MasterBus needs a
terminator on both ends of the
network. · The electric power for the network comes from the
connected devices according to the rule: 1 powering/3 non powering. · Do not
make ring networks. · Do not make T-connections in the network.

7 TROUBLE SHOOTING
In case of a failure, the Mass Charger display shows an error `code’ to help you find its source. See section 5.6 LED indicators, on page 14. If you cannot solve a problem using the following fault-finding table, contact your Mastervolt dealer. Make sure you have the part and serial number at hand (See section 1.4, on page 3).
Malfunction No output voltage and/or current
Output voltage too low, charger supplies maximum current Charge current too
low
Batteries not fully charged
Batteries are discharged too fast Batteries are too warm, gassing
Possible cause No AC input. AC input voltage too low (< 180VAC). AC input
frequency out of range. Load that is connected to the batteries is larger than
charger can supply. Batteries not 100% charged.
Batteries almost fully charged.
High ambient temperature.
Low AC input voltage. At lower AC input voltages, the charge current is
reduced. See Figure 8 on page 22. Charge current too low. Current to load is
too high. Charge time too short. Battery temperature too low. Defective or old
battery. Battery capacity reduced due to wastage or sulphation, stagnation.
Defective battery (short circuit in cell). Battery temperature too high.
Charge voltage too high.
What to do Check AC wiring, check remote control panel. Check input voltage,
check generator. Check input voltage, check generator. Reduce load taken from
the batteries.
Measure battery voltage. After some time, this will be higher. Nothing, this
is normal when the battery is almost fully charged. Nothing; if ambient
temperature is more than 40°C the charge current is automatically reduced.
Check AC input voltage.
See “Charge current too low”. Reduce load taken from the batteries. Use a
battery charger with higher capacity. Use the battery temperature sensor.
Check battery and replace if necessary. Charge and recharge a few times, this
might help. Check battery and replace if necessary. Check battery and replace
if necessary. Use the battery temperature sensor. Check settings (see section
6.3 on page 15).
