Safety
This chapter provides an overview of the safety precautions that must be observed when operating the
instrument. For personnel and system safety, and to obtain optimum performance, read this manual
carefully and thoroughly before installing, using, or maintaining the instrument.
NOTICE
The design of this guide is based on the assumption that the CoreSense™ M10 system
is installed on a de-energized transformer. However, it is possible to install the system
on an energized transformer, assuming that all necessary safety precautions are heeded.
See “INSTALLATION ON ENERGIZED TRANSFORMERS” on page 9 for important
information about installation of CoreSense M10 systems on energized transformers.
If you do not fully understand the information contained in this guide, or if the instrument shows any
