BEFORE YOU START
6 October 2011 / Sunmaster XS4300-3200-2000 / EN
3 BEFORE YOU START
3.1 UNPACKING
In addition to the Sunmaster the delivery includes:
• A mounting bracket to mount the Sunmaster to a wall
• This user’s and installation manual.
After unpacking, check the contents for possible damage.
Do not use the product if it is damaged. If in doubt, contact
your supplier.
3.2 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).

WARNING
Never use the Sunmaster for a non-intended
application!
3.3 INSTALLATION ENVIRONMENT
• Ambient temperature: -20 ... 60°C; (power derating
above 45°C).
• Installation in an indoor, conditioned or unconditioned
environment (See the table below for more
instructions)
• 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.
• 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.
Install the Sunmaster XS indoor. A
conditioned environment is
recommended.
