Safety SMA Solar Technology AG
2 Safety
2.1 Appropriate Usage
The PT100M temperature sensor is a module temperature sensor. It consists of a PT100 measurement
resistor which is embedded in a plastic pipe. The measuring range of the module temperature sensor
is between -20 °C and +110 °C.
To pro ces s th e am bie nt d ata , the se nso r mu st b e co nne cte d 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 installation guide and the Sunny Central 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 Control,
the corresponding overvoltage protectors can be ordered as an option from Sunny
Central.

C 2 Adhesive tape strips

3.2 Identifying the Module Temperature Sensor
The module temperature sensor can be identified by measuring the measurement resistance. The
nominal resistance equals R0 =100 Ω (at 0 degrees).
4 Installation and Electrical Connection
The PT100M module temperature sensor can be connected to the Sunny Boy Control Plus, the Sunny
Central or the Sunny SensorBox. Take into account the prefabricated cable length of 2.5 m. If the
cable length is insufficient, you can extend it using a junction box, for example over a 2 or 4-wire
system.
2-wire system
When connecting the temperature sensor in a
2-wir e syst em, the cable r esist ance is includ ed in
the measurement. Depending on the cable
length, this can lead to inaccuracies when
measuring.
The 2-wire system should therefore only be used with short cable lengths (maximum 3 m)
or where the necessary degree of measuring accuracy is not as high. In order to improve
the measuring accuracy, the use of a 4-wire system is recommended.
Installation Guide PT100MNR-IEN083510 7
Installation and Electrical Connection SMA Solar Technology AG
4-wire system
To offset measuring errors which occur as a
result of cable resistance, connect the
temperature sensor via a 4-wire system. This
type of connection ensures the current feed and
voltage measurement are performed by separate pair cables. The cable length must not
exceed 30 m.
Protect the connection interfaces against weather conditions.
When extending the sensor cable, protect the connection interface against weather
conditions (e.g. by using a junction box or terminal box).
4.1 Cabling Recommendations
The cable length and quality will affect the signal quality. To achieve a good quality signal, observe
the following cabling instructions:
Outdoors
For outdoors, use a cable with the following basic properties.
• Cross-section: min. 4 x 0.25 mm
•UV-resistant
We recommend the following cable types:
• Lapp cable: Unitronic S-LifY11Y 4 x 0.34 mm
• UL-listed Lapp cable: UNITRONIC S-LifY11Y 4 x 0.34 mm², order no.: 7038 865
Indoors
If you protect the cable against UV radiation for use outdoors by means of a suitable cable channel,
you can also use a non-UV-resistant (indoor) cable with the basic properties mentioned above.
We recommend the following cable types:
• Lapp cable: Unitronic LiYY 4 x 0.25 mm
• UL-listed Lapp cable: UNITRONIC LiYY UL/CSA 4 x AWG22/7, order no.: 0022 604
• Helukabel: TRONIC LiYY 4 x 0.25 mm

4.2 Selecting Where to Install
Consider the following points when selecting where to install:
• Select a solar cell which is never in the shade during the day.
• The module temperature sensor is fixed to the rear.
• Take into account the prefabricated cable length of 2.5 m.
