2.1 Appropriate Usage
The PT100U ambient temperature sensor consists of a PT100 measurement resistor which is installed
in a lP65 plastic enclosure. The PT100U temperature sensor enables measurements in either a 2- or
4-wire system as desired. The measuring range of the ambient temperature sensor is between -30 °C
and +80 °C. To process the ambient data, the sensor 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
ATTENTION!
Damage to the sensors as a result of incorrect connection to the Sunny Boy
Control Plus or Sunny Central Control.
The Sunny Boy Control Plus installation guide and the wiring diagram provided must be
used for establishing the electrical connections and connectors.
ATTENTION!
Destruction of the PV system by a lightning strike.
All devices installed on a rooftop must be integrated into 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, the
corresponding overvoltage protectors can be ordered as an option from Sunny Central.
