CAUTION Verify that the DGA monitor is correctly wired and grounded before turning it on.
CAUTION If the circuit breakers will not stay in the ON position, turn off Mains power to the DGA monitor immediately and inspect the Mains and OPTPSU power wiring. The circuit breakers may be tripping because of a loose wire or incorrect connection.
Make sure the DGA monitor is in an upward position before turning it on. Turning on the DGA monitor in any other position will result in a float sensor error.
Figure 1. Turning on DGA monitor in an upward position
  1. Verify that the circuit breakers Main and Heat inside the DGA monitor are turned on.
  2. Turn on Mains power from the external disconnection device.
  3. Turn on the circuit breaker F1 Main and switch S1 inside the power supply unit.
  4. Check the DC OK LED on the power supply:
    • If the LED is lit solid green, OPTPSU power to the DGA monitor is successfully turned on.
    • If the LED keeps blinking, it is likely that the 24 V DC connection to DGA monitor is wired incorrectly. Turn off switch S1 and Mains power, and correct the problem before attempting to power on the DGA monitor again.
