• if the Ethernet connection is used, the transformer secondary must be connected to earth;
• a power supply voltage other than that specifi ed may seriously damage the controller;
• it is recommended to separate the power supply to the controller and the terminal from the power supply to the other
electrical devices (contactors and other electromechanical components) inside the electrical panel.
