Sensor Box Professional
2.3 WiringtheDataCablewiththeSolar-Log™
The Sensor Box Professional is connected via the RS485 gateway with the Solar-Log™. The 4-core connection cable
between the irradiance sensor and the Solar-Log™ is used for data exchange and 12 V power supply. A separate
mains adapter is not necessary.
The connection cable can be extended (max 50 m). Please be sure that the supply voltage 10,5 VDC reaches the
end of the connection cable. For longer distance please use a cable with bigger wire cross section.
For outdoor use, the connection must be protected in conformity with IP54. For indoor wiring, please use a
shielded data cable. The shield of the cable must be connected with a potential equalisation. The 4 wires of the
connection cable have to be connected with the Solar-Log™ connection plug.
Warning!
Interchanging the connection cables may result in damage to sensor.
