Installation Guide
AC power line terminal block
The CoreSense is an overvoltage category II instrument.
The AC voltage must be between 100 V and 240 V and have a minimum capacity of 1 A.
The frequency must be between 50 Hz and 60 Hz.
The AC power must be supplied through a 12 AWG cable of at most 15 m (50 ft.) or a 14 AWG cable of at
most 10 m (33 ft.) with an overcurrent protection (see “Planning your cabling” on page 11).
WARNING
An external circuit breaker with a rating of 15 amps must be installed on the AC source
and labeled accordingly, in accordance with your country’s national electrical code.
NOTICE
For configuration purposes, the sensor can be powered when it does not contain
any oil. However,
the thermal pump must be turned off
(this can be done in the web
interface [in Settings/administration settings]).
The CoreSense is delivered with the thermal pump turned off to avoid accidents.
Operating the heater in air will result in failure of the thermal pump.
The cable glands must be torqued to 3.6 N·m to ensure safe installation.
Make sure the power cord is properly secured.
When the installation is complete and the sensor is in contact with oil, make sure that the thermal
pump is enabled in the web interface.
