CHAPTER 3
Preparing for installation
Installing the CoreSense™ M10 monitoring system requires some planning. You need to plan:
• the physical location of the monitoring system analytical unit and sensor head,
• the power supply to the analytical unit cabinet (connection location, need for additional fuses, etc.)
• the necessary cables (see “Electrical specifications” on page 83 and “Communication” on
page 86,
• the required tools.
On a transformer, several mounting locations may be available for installing the analytical unit and
sensor head (see Figure 12 and Figure 14) (see also “INSTALLATION ON ENERGIZED TRANSFORMERS”
on page 9).
Care should be taken to select a mounting location:
• where the analytical unit will have sufficient clearance.
• that will allow for the analytical unit touchscreen to be positioned at eye level.
• where the sensor head will be exposed to maximal oil flow and minimal oil temperature fluctuations.
Considering meteorological conditions
Installation of the CoreSense M10 monitoring system should not be performed under the following
meteorological conditions:
• In rain
• In snow
• In highly
windy/dusty conditions
• At temperatures below 5 °C (41 °F) or above 40 °C (104 °F)
• If the relative humidity level is above 80%.
(at temperatures up to 31 °C [87 °F], and decreasing linearly to 50% at 40 °C [104 °F])
NOTICE
The installator may pre-assemble the CoreSense M10 (connecting the sensor head conduit
to the open analytical unit cabinet, close the cabinet) in a temperature- and humidity-
controlled location (building, back of truck, etc.) that meets the proper environmental
standards, and then bring the whole assembly on location where installation can be
completed regardless of meteorological conditions.
Also, the installator can build a temperature-controlled temporary shelter at the
installation location and proceed to the installation there as long as environmental
conditions are met.
