Overvoltage protection
The RESOL overvoltage protection device SP1 should be used in order to protect the
susceptible temperature sensors in or at the collector against induced overvoltages.
In the case of local thunderstorms, voltage peaks which could destroy the sensor can be
induced in the sensor cable. The protector diodes in the SP1 limit these overvoltages
to a value harmless to the sensor.
The best way to protect the sensor is to install this connecting box close to the sensor.
Because of the weather conditions, the SP1 is designed as a robust connecting box in a
dripping water-protected housing which can be used outdoors. Seven rubber glands for
the sensor cables in the side walls of the connecting box allow for an easy installation
in each position.
