Use the suitable personal protection devices and adhere to the current regulations governing electrical safety. This device must be installed exclusively by qualified personnel who have read all of the information relative to the installation. Check that the voltage supply and measurement are compatible with the range permitted by the device. Ensure that all current and voltage supplies are disconnected prior to carrying out any controls, visual inspections and tests on the device. Always assume that all circuits are under voltage until they are completely disconnected, subjected to tests and labelled. Disconnect all of the power supply prior to working on the device. Always use a suitable voltage detection device to check that the supply is interrupted. Pay attention to any dangers and carefully check the work area ensuring that no instruments or foreign objects have been left inside the compartment in which the device is housed. The correct use of this device depends on a correct manipulation, installation and use. Failure to adhere to the basic installation information can lead to injuries as well as damage to the electric instruments or to any other product. NEVER connect an external fuse in by-pass. Disconnect all of the input and output wires before carrying out a dielectric rigidity test or an insulation test on an instrument in which the device is installed.
