COUNTRY SELECTION

The Sunmaster is equipped with an anti-islanding device
that ensures the switch off in case of grid failure. European
countries maintain different regulations with regard to the
grid interface of solar inverters. The common islanding
device is the QNS, which switches off the inverter if the
grid voltage or frequency is out of range. In some
countries like Germany the ENS device (VDE-V-0126-1-1
compliant) is compulsory.
Because of these different regulations the Sunmaster must
be configured at first installation. See section 4.3.2.
Furthermore the Sunmaster can be supplied with or
without internal DC switch which is used to disconnect the
photovoltaic modules from the inverter, as required in
buildings by the international standard IEC60364-7-712.
Check from the part number on the type number plate
whether the Sunmaster is appropriate to be used for the
intended application (refer to table 1).

3.3
The Sunmaster can be mounted in the AC distribution
cabinet or in the vicinity of the solar panels. Obey the
following stipulations during installation:
•
The Sunmaster is designed for both indoor and
outdoor use, according to safety class IP44. Among
others this means that the Sunmaster should not be
exposed to direct weather conditions such as rain or
snow. Therefore the Sunmaster should at least be
installed under a canopy roof for protection against
rain.
•
Do not install the Sunmaster in dusty environments.
•
Ambient temperature: -20 ... 60°C; (power derating
above 45°C).
•
No objects must be located within a distance of 10 cm
around the Sunmaster (figure 3).
•
Make sure that the hot air that is generated during
operation will be discharged by forced ventilation when
installing the Sunmaster in a closed section.
•
Keep at least 50 cm in between the inverters when
several Sunmasters are installed next to each other
(figure 5). If this is not possible, adequate measures
must be taken to avoid one inverter heating up the
other (figure 4).
•
If the Sunmaster is installed in the immediate vicinity of
living areas, take into account that the Sunmaster can
produce a slight noise level when operating (refer to
section 7.1).
•
Mount the Sunmaster vertically on a solid wall.
•
Readability of the display is optimal when looking at
the display from an equal or lower position.
