Safety
This transducer must be used in electric/electronic equipment with respect
to applicable standards and safety requirements in accordance with the
manufacturer’s operating instructions.
Caution, risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (eg. primary connections, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
This transducer is a build-in device, whose conducting parts must be inaccessible
after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.

●● IS is positive when VP is applied on terminal +HV.
●● The primary circuit of the transducer must be linked
to the connections where the voltage has to be
measured.
●● Installation of the transducer must be done unless
otherwise specified on the datasheet, according to
LEM Transducer Generic Mounting Rules. Please
refer to LEM document N°ANE120504 available on
our Web site: Products/Product Documentation.
●● This is a standard model. For different versions
(supply voltages, turns ratios, unidirectional
measurements...), please contact us.
