Improper use

For configuration purposes, the sensor head can be powered when it does not contain any oil.
However, the thermal pump must be turned OFF. This can be done via the web interface (for more
information, see "Activating the thermal pump" on page 69). The CoreSense M10 is delivered with the
thermal pump turned OFF.
When installation is complete and air has been purged from the sensor head, make sure to enable the
thermal pump via the web interface.
NOTICE
The thermal pump is designed to operate while immersed in transformer oil. It will fail
within minutes if operated in air.
It is prohibited to use the monitoring system for any of the following (including, but not limited to):
• A climbing aid, e.g., for mounting purposes.
• A support for external loads, e.g., as a support for pipes.
• By adding material, e.g., by painting over the name plate, or welding/soldering on parts.
• By removing material from the sensor head, e.g., by drilling the housing.
Repairs, alterations, and enhancements, or the installation of replacement parts, are only permissible
as far as these are described in this manual. Approval by ABB must be requested in writing for any
activities beyond this scope. Repairs performed by ABB-authorized centers are excluded from this
article.
