8 en | Safety Notes DiBos/DiBos Micro 10. Power source The device must only be operated with the power source indicated on the label. If you are not sure whether you can operate the device with a specific power source, ask the dealer from whom you bought the device or your electricity provider. You will find more information on devices that can be operated with batteries in the operating manual. For devices that are operated using external power units, only recommended and tested power units should be used. For devices that are operated using power units with limited power, the power unit must conform to the EN 60950 standard. Other replacement power units may damage the device and lead to fire or electric shock. For devices that are operated using 24 V AC, the normal input voltage is 24 V AC. The input voltage to the device should not exceed 30 V AC. The wiring provided by the customer for connecting the power source to the device (24 V AC) must conform to electrical codes (Class 2 power stages). The power source (24 V AC) must not be grounded at the connectors or the power supply connections on the device. 11. Coax grounding If a cable system is connected to the device for outside use, ensure that the cable system is grounded. Only for models available in the USA: Section 810 of the National Electrical Code, ANSI/ NFPA No.70-1981, contains information on the correct grounding of the mounting, coax grounding at a discharge device, the size of the ground conductors, the location of the discharge device, connection to discharge electrodes and requirements regarding the discharge electrodes. 12. Grounding or polarizing This device may have a polarized AC plug (a plug with one pin broader than the other). With this protection system, the plug can only be inserted into a socket in one way. If you are unable to insert the plug fully into the socket, rotate it and try again. If you are still unable to insert the plug, ask an electrician to replace the socket with a later model. Do not attempt to bypass the polarized plug. Alternatively, the device may have a 3-phase ground plug with a third (grounding) pin. With this protection system, the plug can only be inserted into a grounded socket. If you are unable to insert the plug into the socket, ask an electrician to replace the socket with a later model. Do not attempt to bypass the grounded plug. 13. Lightning For added protection of the device during a storm, or when it is not used for a lengthy period of time, unplug the device from the mains and disconnect the cable system. This prevents the device being damaged by lightning or a power surge. 14. The installation location should be quiet and have only limited access.
