The operating spe-cifics of each feature package are described below.The Eaton SPD Series requires no operator involvement, otherthan to monitor the display panel to determine status of theSPD.After system power is applied, the SPD automatically beginsprotecting downstream electrical equipment from voltage tran-sients.Some SPD units have a Form C relay contact that allows for theremote indication of SPD status. Form C contact wires are per-manently connected to the SPD.3.2 Displays and IndicatorsAll Eaton SPD Series units (Basic, Standard, and Standard WithSurge Counter) use a display panel to indicate system status.The display panel is slightly different for each feature package.Each display has both green and red light emitting diodes(LEDs) to indicate the status of the protection on each phase.Green indicates the phase is fully protected. Red indicates aloss of protection.
