SETTINGS

4.9.1

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 figure 3).
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.
4.9.2

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 figure 3). 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 figure 3).
Stand-by mode settings:
• energy mode
• stand by mode
• stand by
• stand by hysteresis
NOTE:
Adjust the settings prior to commissioning!

4.10 COMMISSIONING

CAUTION!
Check the polarity of all wiring before
commissioning: plus connected to plus (red
cables), minus connected to minus (black
cables)
Follow the steps described below to switch on the Mass
Sine.
1 Tighten all cable glands to ensure the pull relief

2 Check all wiring and connections
3 Close the front cover plate of the connection
compartment of the Mass Sine. Beware that the wiring
does not obstruct the cooling fans and air flow.
4 Place the DC-fuse(s) of the DC-distribution to connect
the batteries to the Mass Sine.
WARNING
When placing this fuse, a spark can occur,
caused by the capacitors used in the Mass
Sine. This is particularly dangerous in places
with insufficient ventilation, due to the gassing
of the batteries an explosion can occur and
avoid having flammable materials close by.
Now the Mass Sine is ready for operation.

4.11 DECOMMISSIONING

If it is necessary to put the Mass Sine out of operation,
follow the instructions in order of succession as described
below:
1 Move the Main-switch of the Mass Sine to the "Off"-
position (see figure 2).
2 Remove the DC-fuse(s) of the DC-distribution and/or
disconnect the batteries.
3 Open the connection compartment of the Mass Sine
4 Check with a suitable voltage meter whether the
inputs and the outputs of the Mass Sine are voltage
free.
5 Disconnect all the wiring
Now the Mass Sine can be demounted in a safe way.

4.12 STORAGE AND TRANSPORTATION

When not installed, store the Mass Sine in the original
packing, in a dry and dust free environment.
Always use the original packing for transportation. Contact
your local Mastervolt Service Centre for further details if
you want to return the apparatus for repair.

4.13 RE-INSTALLATION

To reinstall the Mass Sine, follow the instructions as
described in this chapter (chapter 4).
