## **Safety** 

This transducer must be used in limited-energy secondary circuits according to IEC 61010-1. 

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 busbar, 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.

## **Remarks** 

- _U_ out is positive when _I_ P flows in the direction of the arrow. 

- ●Temperature of the primary conductor should not exceed 100 °C. 

- ●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: . 

- **https://www.lem.com/en/file/3137/download/** 

- ●The retrun busbar and primary conductor elbow must be located at least at 2.5 mm × window length more far away from the transducer case. 

- ●Dynamic performances are best with a primary busbar completely filling the primary aperture. 

- ●This is a standard model. For different versions (supply voltages, turns ratios, unidirectional measurements...), please contact us.
