With the ET energy optimisation adapter, the power supply can be interrupted unnoticed from outside. Here, the control signals (24VDC) are connected via the 4-pole OPT interface either to an energy optimisation system according to DIN 18875 or to an additional switching contact (bridge) for manual operation.
As long as signals b and c are connected at the 4-pin OPT interface, there is no power interruption. Three LEDs indicate the status of the signals a = ready for operation (orange), b = energy demand (red) and c = energy release (green)
