2 Safety
2.1 Appropriate Usage
The RA100T is a modular irradiation and temperature sensor. The sensor consists of a monocrystalline
silicon solar cell and an integrated temperature sensor module PT100. The irradiation sensor is
calibrated to 25 °C; the measuring range can be found on the sensor's type label. The measuring
range of the temperature sensor is between -30 °C and +50 °C.
In order to process the ambient data, the sensors must be connected to the Sunny Boy Control Plus or
the Sunny Central Control.
The sensor is only suitable for use with original SMA accessories or with accessories recommended
by SMA Solar Technology AG.
Appropriate usage also includes observing all further documentation relating to this device and its
components.
2.2 Safety Instructions
NOTICE!
Damage to the sensor as a result of incorrect connection to the Sunny Boy
Control Plus or Sunny Central Control.
The Sunny Boy Control installation guide and the wiring diagram provided must be used
for establishing the electrical connections and connectors!
NOTICE!
Destruction of the PV system by a lightning strike.
All devices installed on a rooftop must be integrated in the existing lightning protection of
the PV system.
Overvoltage protector
Protect your PV system components against overvoltage from outside by connecting the
sensors to an overvoltage protector. For using the sensors with the Sunny Central Control,
the corresponding overvoltage protectors can be ordered from Sunny Central as an
option.
