This multi-colored light displays 4 separate UPS load conditions.
It will turn from green (low) to yellow (medium) to red (high) as you
connect equipment to show you the load level your UPS is support-
ing. When the light is red your UPS is supporting a load above 85%
of its capacity. If the red light begins flashing, your UPS is severely
overloaded. Remove overload immediately until light stops flashing.
