Green LED illuminates green to signal that the –48 VDC power supply input
voltage is greater than–43.5VDC at turn-on and remains green down
to –39VDC.
Amber The LED illuminates amber when the input voltage (falls below
–39VDC) and indicates that there is still a voltage present (voltage on
the terminal block). The LED remains amber and is active to around
20 V +/-5 V. The LED is not illuminated if the input is below –15 V.
