Ultra, the Safety Guidelines and Warnings are applicable at
all times. See chapter 2 of this manual.

In addition to the Mass Sine Ultra the delivery includes:
this user’s manual;
MasterBus terminating device.
After unpacking, check the contents for possible damage.
Do not use the product if it is damaged. If in doubt, contact
your supplier.
Check from the identification label (see section 1.7) whether
your Main battery voltage is the same as the DC-input
voltage of the Mass Sine Ultra (e.g. 24 V main battery set for
a 24 V input voltage). Also check that the AC output voltage
and output power of the Mass Sine Ultra complies with your
system and loads.
4.2 Environment
Obey the following stipulations during installation:
The Mass Sine Ultra is designed for indoor use only.
Ambient temperature: -25˚C to 60˚C, (power derating
above 40˚C).
Maximum usage/installation height: 2000 m.
Humidity: 0-95% non-condensing.
Mount the Mass Sine Ultra on a solid surface, with the
connecting cables downwards.
Make sure that the hot air produced during operation can
be discharged. The Mass Sine Ultra must be mounted in
such a way that obstruction of the airflow through the
ventilation openings will be prevented.
No objects must be located within a distance of 10 cm /
4 inch around the Mass Sine Ultra. Keep at least 15 cm
/ 6 inch free space below the Mass Sine Ultra.
Do not locate the Mass Sine Ultra in the same
compartment as the batteries.
Do not install the Mass Sine Ultra straight above the
batteries because of possible corrosive fumes.

The wiring is connected inside the connection compartment.
If necessary, the wiring can be fed from the top to the bottom
side of the cabinet along the back of the cabinet.
Always feed the wiring through the strain reliefs of the
cabinet, and then connect the wiring to the terminals.
Connect the phase line wire to terminal L, the neutral wire to
terminal N and the ground wire to terminal PE, see figure 4-
