From page 4 of the manual. Amber light is low voltage. see figure 2. Time for a volt meter.
FAC Voltage Input Indicators
The WF-8500 Series Power Centers have built-in indication of the incoming AC voltage.
Three LEDs give at-a-glance status of Low, Normal or High voltage. See Figure 2 below.
If the incoming voltage is within the normal operating range of 105 to 130 VAC, the Green
LED will be illuminated. However, if the incoming voltage is less than 105 VAC, the Yellow
LED will illuminate. If the incoming voltage is greater than 130 VAC, the Red LED will
illuminate. If either the Red or Yellow LED is illuminated, shut down the WF-8500 Series
Power Center and investigate the cause of the problem.
