    OPT100 Installation Guide M211857EN-R 2. Planning the installation 2.1 Installation safety WARNING! Read the product documentation carefully before installing or operating the product. If you encounter the following marking during installation or operation, consult product documentation to find out the nature of the potential hazards and any actions which have to be taken to avoid them: WARNING! Only licensed experts may install electrical components.

  • Page 11: Installation Phases

    Chapter 2 – Planning the installation CAUTION! Surfaces inside DGA monitor that are marked with the symbol below heat up during normal operation. Avoid touching hot surfaces and wear protective gloves when working inside the cabinet. Whenever possible, allow the DGA monitor to cool down before starting the work. Wear protective eyewear and gloves.

    • Operating altitude: DGA monitor is intended for use in altitude range -1000 … 3000 m. If you have any questions, contact Vaisala for more information. Performing a site inspection in person is a good idea. Take photographs of the intended installation location, oil connections, and electrical connections.
  • Page 16 OPT100 Installation Guide M211857EN-R • The recommended arrangement is to use two valves in different locations on the transformer. This improves oil circulation inside the transformer and prevents the returned oil from immediately mixing with the next sample. • Use the same valve for oil intake that has been previously used to take oil samples. This makes the measurements results of the DGA monitor more comparable with previous laboratory analysis results.
