    After the start-up operations have been completed, perform a manual battery test: press button 3 and then 2 on the control panel. At the end of the test, after approx. 8 seconds, with the CPS started correctly and with the battery connected on the signals and control panel, the two green input and output LEDs must be on constant.

    The various equipment operating modes are described below. setting The operating mode is set when the CPS is installed; it may be changed subsequently but this should always be done by a specialized technician. 4.8.1 On - line - factory setting - load always powered by inverter, in the event of an input mains failure the load continues to be powered from the inverter using the energy stored by the batteries.

  • Page 26: Standby-Off (With Mains Present The Load Is Not Powered)

    Standby-Off: if there is a mains power supply, CPS output is zero. The RECTIFIER remains on and keeps the battery charged. The output voltage is only present when the mains power supply fails. The system remains with output voltage = 0V while the voltage and the input frequency are within the acceptance field.
