The installed DEGERtraker tracking system has to be protected against trespassing in its
whole sphere of action by adapted measures, for example by errecting a fence.
While assemblage of the DEGERtraker or parts of the system and while the system is put
into operation some risks of injury exist caused by moveable parts of the tracking system. To protect injuries
caused by possibly existing burrs or sharp angles we imperatively recommend to wear gloves when
mounting the steel parts of the system.
In case of checks or changes at the DEGERtraker all parts of the system have to be free of
potential through a Customer-supplied electrical power switch. Zero-potential and mechanical protection
have to be proven and guaranteed due to the “General rules for accident prevention”. When voltage supply
is indispensable for checking the system injuries of persons have to be ruled out by adapted actions.
Lightning protection and grounding should be installed/designed in accordance with state
specific requirements and national standards for photovoltaic systems.
The whole sphere of action has to be free of any objects.
Elevation-axle and azimuth-axle of the DEGERtraker can be moved manually by the enclosed Central
Control Box (CCB). Therefore please pay attention to part V of this assembly instruction.
To move the traker safely in the horizontal position in case of power failure we recommend
to use a uninterruptible power supply. When all electrical components fail the systems can be moved into the
horizontal position by using standard tools. (see III-6)
The development of the DEGERtrakers is based on the DIN 1055-4. Reducing the module surface the
system will be able to resist higher demands than the values given in the norm. The maximum mountable
module surface depends on regional conditions and regulations. To calculate the maximum mountable
module surface a dimensioning-tool is available on our website. The download of the dimensioning-tool is
free.
DEGERtrakers can also be set up in earthquake endangered zones without reservation in respect
of module area or foundations geometry.
In case of accumulation of snow on the module surface with more than 35kg/m²(equivalent
to about 8 cm wet snow and about 15 cm powder snow) it is necessary to broach the module surface. It is
possible to do this by activating manually the CCB as described above.
For 6000NT and 9000NT the snow sensor is mandatory. Upon failure of the snow sensor,
it is necessary to
tilt the module surface
at a load of more than 10kg/m².
Intended Use
A DEGERtraker is designed and dimensioned to be applied with standard-photovoltaic
modules and is therefore not adapted to be applied with concentrator modules, mirrors, solar thermal
collectors etc. The maximum mountable module surface calculated by the dimensioning-tool must not be
exceeded in any case. As soon as the modules are mounted an operating wind guard has to be assembled
or the module surface has to stay in the horizontal position.
Permissible ambient temperature:
-20°C to +55°C
Sound level
Distance 20m:
no difference to the sound level of the surrounding measurable
Distance 10m:
40 dB(A)
Reference value: 40 dB(A) corresponds to:
- tweet of a bird
- usual background sound level in a house
