Installation 133 of 268
Module temperature sensor
Module temperature is detected by an integrated cell sensor, thus avoiding the
costly process of mounting a sensor on the back of the module.
Fitting optional sensors
The temperature sensor must be fitted in a shady place with a wall bracket.
The connection plug is screwed firmly into the 3 pin inlet on the radiation sensor.
As far as possible, the wind wheel should be installed in a high, exposed posi-
tion using the mounting bracket. The connection plug is screwed firmly into the
2 pin inlet on the radiation sensor.
Cabling for the data line to the Solar-Log
1000
The sensor box is connected to the Solar-Log using the RS485 interface.
The connection cable between the radiation sensor and the Solar-Log has
4 wires and includes the 12 volt power supply and the data line to the Solar-
Log. A separate power supply unit is not required.
The connection cable can be extended (up to 100 m). However, a 12 V supply
voltage must be provided at the end of the cable. For longer stretches please
select a larger cable cross section.
The cable must be suitably protected in outside areas. (IP54). The cabling in
inside areas can consist of a shielded data cable. The cable shielding must
have an equipotential bond. The four wires in the connection cable must be
connected to the 4 pin connection plug on the Solar-Log™.
Commissioning the Solar-Log™
When the Solar-Log is switched on, the sensor box is also powered up au-
tomatically. Then the sensor box must be configured to the required free
RS485 interface:
1. On the screen call up Config/Start/Initial configuration. To do this also
see the installation handbook Chapter 7 - Commissioning
2. When selecting the inverter tick MT sensor.
3. Carry out inverter detection.
The sensor box is integrated into the system like an inverter.
Further configuration is done using the Solar-Log web interface.
