20. Place the equipment door side up in the original packaging, if available. Safe lifting and
carrying of the DGA monitor requires two people.
If original packaging is not available:
• Use double wall cardboard boxes. If both OPT100 DGA Monitor and OPTPSU power
supply unit are sent, pack them in separate boxes.
• Protect the main cabinet fittings at the bottom. Fill the box with enough protective
material that the equipment cannot move around in the box.
• Close the box with plastic tape and add bands around the box.
21. Ship with "fragile" markings.
4.7.1 Forcing uninstallation
Use forced uninstallation only if normal uninstallation cannot be
completed, the device is faulty or the oil pipes have already been disconnected.
CAUTION!
If forced uninstallation is not completed correctly, it may cause
damage to the transformer.
CAUTION!
Do not transport the DGA monitor without uninstalling it properly:
• If the oil connections are not properly plugged, oil will drain out from the DGA
monitor during transport.
• Oil may contaminate the optical measurement module during transport
unless you complete the uninstallation procedure successfully and lock the
bleed valve manually.
CAUTION!
You need to be on site to complete this task.
Wear protective eyewear and gloves.
1. Connect to the DGA monitor user interface and log in as an Admin user.

3. Wait for DGA monitor to enter Standby mode. Depending on the stage in the
measurement cycle, stopping may take up to 60 min.
