MAIN POWER SUPPLY Devices with OPTION L provide low voltage power supply input in a wide voltage range. The power supply must not be shared with other equipment and meet SELV circuit requirements according to EN/IEC62368: Suggested power source is a cheap 12VAC / 10VA transformer. Length between power supply source and device must be less than 3 m. |

OPTION B devices accept power from a long-lasting, non-rechargeable external battery. Typically lithium thionyl chloride cells with additional capacitor for impulsive use. This solution can be adopted for applications that remain for long periods in low-power mode with periodic wake-up and short-term operations. |

WARNING connections with reversed polarity DO NOT DAMAGE the device but PRODUCE A REPENTINE DISCHARGE OF the battery After connecting the battery (and after each switching off of carried out with the appropriate command) it is necessary to connect the auxiliary power supply (RJ45) even for a short moment to start the device. |
