3 INSTALLATION

During installation and commissioning of
the MASS inverter, the Safety Guidelines
and Measures are applicable at all times.
See chapter 2 of this manual.

3.1 ENVIRONMENT

Install the MASS inverter in a dry, well ventilated,
dust free situation. Locate the inverter as close as
possible to the DC distribution in order to keep the
battery cables short. Do not locate the inverter in the
same compartment as the batteries. The heat of the
inverter is discharged by a fan with a variable speed,
from the top and side of the cabinet to the bottom of
the cabinet.

When fitting the inverter be sure that:

• the air flow is not obstructed;

• the inverter is mounted vertically;

• no water and/or dust can enter the cabinet.

Never use the inverter in locations where
there is gas or explosion danger!

3.2 WIRING

The routing of the wires has influence on the EMC
behaviour of the system in which the inverter is a
component. This is caused by the fact that wires are
excellent receivers and transmitters of radio frequen­cy electro magnetic interference. Most problems ori­ginate from mutual influencing between wires and
cables.

Never remove the type number plate!
Important technical data required for servi­ce, maintenance and later delivery of parts
can be obtained from the type number
plate (see fig. 1).

3.4 CONNECTING

The Mastervolt Service Centers have all accessories
available, e.g. battery terminals and supply cables in
all sizes.

Before beginning to connect the wiring,
make the AC and DC distribution voltage­free.

Opening the front panel

Remove the two Philips screws from the front panel
of the cabinet. Pull the grey front panel away from the
cabinet (downwards). The terminals and cable glands
are now accessible (see fig. 4).

3.4.1 Connecting AC wiring & earth wiring

General:
The inverter is protected against overload and short
circuit, so it is not necessary to install a fuse in the
output of the inverter.

IMPORTANT!

For safe installation it is necessary to:

• connect the earth (PE) and neutral (N) of the

inverter output to the central ground;

• insert a RCCB (earth leakage) switch of 30mA

in the inverter output.

Check whether the voltage from the inver­ter is the same as the connected equip­ment.

The earth wire offers protection only if the
inverter cabinet is connected to the earth.
Connect the inverter's earth terminal (at
the right hand side of the AC terminal
block) to the hull or chassis.

To connect the MASS Sine inverters:
Switch the on/off/remote switch to 'OFF'. The L1, N
and PE terminals are situated on the left hand side
inside the cabinet.

Connect the AC on-board system brown phase 1.5-

2.5 mm2wire to terminal L1, the blue 0-phase wire to
terminal N and the green/yellow earth wire to
terminal PE (see fig. 4).

3.4.2 DC wiring

Keep the cable length as short as possible, this will
keep the system efficiency as high as possible. The
recommended minimum size of the battery cables is:

12/2000 & 12/1200 &

24/2500 48/2500 24/1500

cable thickness 50 mm

2

35 mm

2

35 mm

2

The recommended length is a maximum of 6 meters.
When longer cables are required, use thicker cables.
When possible, use coloured (red and black) battery
cables. If this is not possible, mark the cables with
red and black isolation tape or heat shrink sleeve.

Battery cable connections

Pull the battery cables through the glands at the
bottom side of the inverter. Keep the cable con­nection between batteries and inverter as short as
possible (maximum 6 meters). Connect the black ne­gative battery cable to the negative connection bolt
(right) and the red positive battery cable to the
positive bolt (left) of the inverter. Cut the cables to the
right length and fix, if necessary, connect cable
clamps to both ends. Connect the negative cable to
the negative battery pole and the positive cable via
the inverter fuse to the positive red pole (see fig. 4).

Pull the battery cables through the glands
before you install the cable clamps.

INSTALLATION

November 2000 / Mass Sine 12/1200, 12/2000, 24/1500, 24/2500 & 48/2500/ EN

CAREFUL !
Reversing positive and negative will cause
major damage to the inverter. This damage
is not covered by the guarantee.

CAREFUL !
Too-thin cables and/or loose connections
can cause dangerous overheating of the
cables and/or terminals. Therefore tighten
all connections well, in order to limit tran­sistion resistance as much as possible.
Use DC cables of the correct size.

3.5 CONNECTING THE REMOTE CONTROL
PANEL

The remote control panel C4-RI for the MASS inver­ter comprises an off/on switch and two LEDs. The
LED 'inverter on' indicates proper functioning of the
inverter and the availability of 230/117V AC output
voltage. The LED 'failure' indicates overload, over­temperature or too low voltage. Connect the remote
control panel by means of a telephone cable (not
supplied with the panel), see fig. 5.

3.6 COMMISSIONING AFTER INSTALLATION

Carefully check the polarity of the connections.

Careful !
Only insert the inverter fuse if the polarity is
correct. Switching on with incorrect polarity
will damage the inverter irreparably. The
inverter fuse cannot prevent this.

If the connections are correct:

• check whether the on/off switch is in the “OFF”
position;

• when inserting the inverter fuse, a spark will
occur, caused by the capacitor used in the in­verter. This is normal.

The inverter is now ready for use.

3.7 AUTOMATIC SWITCHING BETWEEN MASS
INVERTER, THE AC GENSET AND/OR
SHORE POWER

Please contact your Mastervolt supplier if you intend
to use the inverter with a genset or shore power
connection. Handswitched or simple relay switching
systems could damage your inverter, because of the
lack off time delay. This kind of damage is not cover­ed by the warranty.

4 OPERATION

4.1 INTRODUCTION

The MASS SINE inverter is a fully automatic high ef­ficiency inverter, developed and produced by Mas­tervolt Amsterdam. The MASS SINE inverter is part
of a series of advanced quality battery chargers and
inverters supplied by Mastervolt all over the world.
The MASS SINE inverter converts DC voltage to
230V AC, 50 Hz. The output voltage of 230V AC has
a sinusoïdal waveform for reliable and trouble free
operation of connected equipment. The inverter is
protected against overload, short circuit and over
temperature. In case of overload, the inverter will re­duce its output power. The MASS SINE inverter has
a very high efficiency of 87%, due to the application
of mosfets with high frequency switching technology.

4.2 SWITCHING ON AND OFF

Switching on:

Put the on/off/remote switch on the front of the
inverter on " on". The green lamp “inverter on" lights
up, and the inverter will start. If you use a remote
control panel, put the on/off/remote switch to ‘re­mote’, and put the on/off switch on the remote control
panel to ‘on’.

Switching off:

Put the on/off/remote switch on the front of the
inverter on " off". The inverter stops and all the lights
that are on, go off.

Careful !
Switching off the inverter with the switch on
the front does not break the connection to
the mains. The inverter remains connected
to the mains.

4.3 INDICATOR LIGHTS

The functions of the indicator lights on the front are:

inverter on: inverter is switched on
overload: inverter is overloaded
overload + on slow: overload in ‘wait’ state
overload + on fast: inverter is switched off
low battery: battery voltage is too low
temperature: inverter is overheated

Short description:

“inverter on”

The green light shows when the inverter is switched
on.

“overload”

Glows if the inverter is overloaded. When the inverter
is overloaded, the power limit reduces the output vol­tage. Depending on the load, the inverter will shut
down after a short period.

“overload” + “on”

When the inverter is in a state of overload for a long
period of time the inverter will switch off and the
overload + on indicators will flash slowly. This takes
approx. 20 seconds after which the inverter automa­tically will restart. This so called wait state gives the
inverter time to recover from any heavy surge loads
and the battery time to recover in case of an empty
battery. When the inverter is switched of 10 times
with intervals no more than 30 seconds apart the
inverter will switch off permanently and the ‘overload’
and ‘on’ indicators will flash fast. To switch the inver­ter on again, you must manually switch the inverter
off and on. When the output is short circuited, the
inverter will go into overload. The ‘overload’ and ‘on’
indicators will flash slowly. The inverter will try to start
up ten times. If the short circuit is not removed, the
inverter will switch off permanently.

Remove the short circuit and reset the inverter by
switching it off and on.

“low battery”

The inverter is switched off if the battery voltage is
too low (see table below). If the voltage rises above
the values given below, the inverter restarts auto­matically.

model 12V 24V 48V
switch off voltage 10V 19V 36V
switch on voltage 11V 22V 44V

“temperature”

The inverter switches off in high ambient temperatu­res and /or sustained overload. After cooling down,
the inverter restarts automatically.

4.4 ON THE REMOTE CONTROL

If you use a remote control panel, put the on/off
switch to ‘remote’, and put the on/off switch on the re­mote control panel to ‘on’.
The meaning of the illuminated LED’s is:

inverter on: inverter is switched on
failure: inverter is overloaded, overheated

or battery voltage is too low

If the failure lamp is lit you can check the nature of
the failure on the inverter front. See fig. 3 for a view
of the panel.

ENERGY SAVING MODES

8 ENERGY SAVING MODES

8.1 LOW ENERGY MODE

For applications that require a very low energy mo­de, it is possible to set the inverter into “low energy
mode”. The “low energy mode” can be selected by
placing a jumper (black) on the two metal pins on the
bottom left of the unit (see fig. 4).
When the jumper is in place, the unit will drop the
output voltage from 230V to 208V at no load cond­itions. In case the inverter supplies 30W or more, the
unit will supply 230V nominal output voltage.

8.2 STAND BY MODE

For applications that require an extremely low
energy mode, it is possible to set the inverter to
‘stand by mode’. The stand by mode can be selected
by placing a jumper (black) onto the metal pins on
the bottom left hand side of the unit (see fig. 4).
When the jumper is in place, the inverter will have no
output voltage but will check the connected output
load once every two seconds. The inverter will switch
on when a load is detected. The stand by power and
stand by hysteresis can be adjusted with the poten­tiometers on the bottom left of the unit (see fig. 4).

Stand by mode settings:

• energy mode low /high energy mode

• stand by mode on/off

• stand by power 0..40 Watt

• stand by hysteresis 0..100%
