    Consumption 9. Consumption 9.1. Tables of consumption In the following table the consumption of the board is shown, the constant minimum consumption (fixed by the permanently active components), the minimum consumption of the electronics included in each group formed by the switches (without sensors) and the individual consumptions of each of the sensors connected alone to the board (the total consumption of the board with a determined sensor will be calculated as the sum of the constant minimum consumption of the board, plus the minimum consumption of the group to whom the sensor belongs, plus the consumption of the sensor).

  • Page 81: Appendix 2: Solar Sensors Mounting Accessory Installation Guide

    Certifications Appendix 2: Solar sensors mounting accessory insta- llation guide This accessory is optional but highly recommended for the solar sensors. With this accessory you will get a secure fastening while keeping the sensor as level as possible, always pointing up. The accessory is composed of 2 main parts: A - Mounting bracket: it will be fastened to a pipe or mast with its u-bolt.
  • Page 82 Certifications Figure: Final look of the whole structure 6 - You may take advantage of the holes on the mounting bracket and the pipe to secure the cable of the sensor, avoiding its rotation. You can do that with some cable ties. To minimize azimuth error, the sensor should be mounted with the cable pointing toward true north in the northern hemisphere or true south in the southern hemisphere.
