For safe installation:
•Connect the grounding point of the AC Master
to the central grounding point of the vehicle/
ship.
•If you need to install a Residual Current
Device (RCD) in the wiring of the AC output,
both the earth (PE/GND) and the neutral (N) of
the AC output of the AC Master must be
connected to the grounding point
Refer to local applicable regulations on these
issues.

USER’S MANUAL AC MASTER ENGLISH
PRODUCT DESCRIPTION AND APPLICATION
The Mastervolt inverter “AC Master” converts a DC
voltage to a pure AC sine wave voltage.
SAFETY INSTRUCTIONS
WARNING!
Before using the AC Master, read and
save the safety instructions
•Use the AC Master in accordance with the
instructions and specifications stated in this
manual.
•Connections and safety features must be
executed according to the locally applicable
regulations
•Operation of the AC Master without proper
grounding may lead to hazardous situations!
•Use DC-cables with an appropriate size.
Integrate a fuse in the positive wiring and place it
nearby the battery. Refer to the specifications.
•If the positive and negative wires on the DC-input
(battery) are exchanged, the AC Master will be
damaged. Damage of this kind is not covered by
guarantee. Check whether all connections are
connected correctly before placing the fuse.
•Do not connect the AC-output of the inverter to
an incoming AC source.
•Never open the housing as high voltages may be
present inside!
UNPACKING
The delivery consists of the following parts:
•The AC Master (incl. DC cables)
•This user’s manual
After unpacking, check the AC Master for possible
damage. Do not use the AC Master if it is damaged.
If in doubt, contact your supplier.
OUTPUT FREQUENCY
See figure 1. On the front side of the AC Master a
small switch (3) can be found to adjust the output
frequency.
The output frequency is factory set to the correct
value. If necessary, use a small flat-blade screw
driver to adjust the output frequency (50 or 60Hz)
CHOOSING A LOCATION TO INSTALL
•Install the AC Master in a well-ventilated room
protected against rain, vapour, moisture and
dust.
•Ambient temperature: 0 ... 40°C;
•Never use the AC Master at a location where
there is danger of gas or dust explosions
•Mount the AC Master in such a way that
obstruction of the airflow through the ventilation
openings is prevented. No objects must be
located within a distance of 10 cm / 4 inch around
the AC Master.
•Use the included battery cables to connect the
AC Master to the DC supply
•Do not install the AC Master in the same
compartment as the batteries. Do not mount the
AC Master straight above the batteries because
of possible corrosive sulphur fumes.

ENGLISH USER’S MANUAL AC MASTER
INSTALLATION
Before you start
•Be sure that the output of the supplying source
(battery) is switched off during installation. Also
be sure that no consumers are connected to the
battery during installation, to prevent hazardous
situations.
•Before installing the AC Master make sure the
main switch (figure 1, ref. 4) is set to the OFF
position.
•Check that the battery voltage is the same as the
input voltage of the AC Master (e.g. 24V battery
for a 24V input voltage). Also check that the
output voltage satisfies loading requirements
•A DC fuse holder must be integrated in the
positive wiring. The DC fuse should be placed
last of all.
•Use four Ø4.5mm screws to mount the AC
Master to a solid surface. See figure 3.
Wiring
•DC Wring. Connect DC wiring as shown in figure
2: the black wire (9) NEG (–) to the negative (–)
pole of the power source / battery, the red
terminal (10) POS (+) to the positive (+) pole of
the power source/ battery. Integrate a DC fuse
holder in the positive wiring, but do not place the
fuse yet. Make sure that all DC connections are
tight.
•Chassis ground: Use a cable AWG8 / 6 mm² to
connect the CHASSIS GROUND terminal (8) to
the central ground.
•120V models (part nr. 28520350): the neutral
connector N of the AC output (1) is
automatically connected to the CHASSIS
GROUND terminal when the inverter is in
operation.
•230V models: the neutral connector N of the
AC output (1) is not connected to the
CHASSIS GROUND terminal.
•Remote operation switch (option). If you want to
operate the AC Master on a remote location, you
can install a switch as indicated in figure 2. When
the contact is closed, the AC Master is switched
on.

COMMISSIONING AFTER INSTALLATION
1. Check the polarity of the DC-connections. Do
not place the DC fuse if the polarity is not
correct.
2. Place a DC-fuse (see SPECIFICATIONS) in the
fuse holder. When placing this fuse, a spark
may occur, caused by internal capacitors of the
AC Master. This is normal.
3. AC voltage: the load can be plugged into the
AC-output (1) directly. Do not connect the AC-
output of the AC Master to an incoming AC
source.
OPERATION
Switching on:
Move the main switch (4) to “ON”. The AC Master
will start a self-test indicated by two beeps from the
buzzer and a flashing LED indicator (2). This may
last for approximate two seconds. Finally the buzzer
will produce another beep and the AC Master will
switch on, indicated by an illuminating green LED-
indicator (2). Now the AC Master is ready to supply
load connected to the AC-output (1).
Switching off:
Move the main switch (4) to the “OFF” position.
Note that switching off the AC Master does not
break the connection to the batteries!
Remote operation:
The AC Master can be operated on a remote
location by means of an optional remote switch.
Move the main switch (4) to the “REMOTE” position.
When the remote contact is closed, the AC Master
is switched on .
LED indicator
The operation mode of the AC Master is made
visible by means of the LED indicator (2)
As long this LED isn’t illuminated red, no failure is
detected: the AC Master is operating normally.
If an error occurs, it is detected by the apparatus
itself: the LED indicator turns red.
Indication of the LED Meaning
GREEN Inverter is working normally
RED Failure. Possible causes:
overload / short circuit
RED blinking Failure. Possible causes:
DC-input voltage too high
or too low, internal
temperature too high,
Maintenance
No specific maintenance is required. If necessary,
use a soft clean cloth to clean the AC Master. Never
use any liquids, acids and/or scourers.
Check the wiring on a regular base. Defects such as
loose connections, burnt wiring etc. must be
corrected immediately.
DECOMMISSIONING
Proceed as follows for decommissioning of the AC
Master:
1. Move the main switch (4) to the OFF position.
2. Remove the DC fuse. Be sure that others can
not reverse this action taken.
3. Now the AC Master can be demounted in a save
way.

TROUBLE SHOOTING
Consult an installer, if you cannot solve the problem by means of the table below.
Problem Possible cause What to do?
Main switch (4) is set to OFF Set the main switch (4) in ON position
Main switch (4) is set to REMOTE,
but no remote present Set the main switch (4) in ON position
The remote switch is off (if applied) Close the remote operation switch
No output voltage, the
LED indicator (2) is off
DC fuse blown Replace the fuse
No output voltage, the
LED indicator (2) is lit red. AC Output overloaded Reduce the load and let the inverter cool down. The AC Master will switch on again when the
internal temperature has reduced
DC input voltage too high Check battery voltage; switch off charger. The
inverter will switch on again if the input voltage is
< 15.5V or < 31.0V
DC input voltage too low (flat battery) Charge the battery. The inverter will switch on
again when the input voltage is > 14.6V or >
29.2V
No output voltage, the
LED indicator (2) is
blinking red.
Airflow insufficient Check the airflow through the inverter. The
operation of the cooling fan (5) should not be
blocked.
DC input voltage too low because of
voltage drop across the DC cables
due to too long or too narrow cables
Reduce the length of the DC cables or use cables
with a larger cross section.
Flat battery Disconnect the load and recharge the battery
Inverter switches on and
off. LED indicator (2) is
blinking alternately red
and green Loose or corroded connections Tighten the connections; burnt cables must be
corrected immediately.
Some loads like
televisions and clocks do
not operate correctly
Wrong setting of output frequency Check the specified input frequency of the load
with the output frequency of the AC Master. If
necessary, adjust the output frequency. See
OUTPUT FREQUENCY.
