## **Conditions of acceptability** 

- _1 - These devices have been evaluated for overvoltage category III and for use in pollution degree 2 environment._ 

- _2 - A suitable enclosure shall be provided in the end-use application._ 

- _3 - The terminals have not been evaluated for field wiring._ 

- _4 -  These devices are intended to be mounted on a printed wiring board of end use equipment. The suitability of the connections (including spacings) shall be determined in the end-use application._ 

- _5 - Primary terminals shall not be straightened since assembly of housing case depends upon bending of the terminals._ 

- _6 - Any surface of polymeric housing have not been evaluated as insulating barrier._ 

- _7 -  Low voltage control circuit shall be supplied by an isolating source (such as a transformer, optical isolator, limiting impedance or electro-mechanical relay)._ 

## **Marking** 

Only those products bearing the UR Mark should be considered to be Listed or Recognized and covered under UL's Follow-Up Service. Always look for the Mark on the product.

The HO-NP gives the same output levels as the HAIS-TP referring to the HAIS nominal currents. This allows easier replacement of HAIS by HO-NP in existing applications.

Notes:[1)] The standard configuration is with all jumpers in parallel (1 primary turn) which is the only one calibrated and guaranteed by LEM. The sensitivity may change slightly for all other configurations, therefore, LEM advises the user to characterize any specific configuration. 

2) The maximum magnetic offset referred to primary is inversely proportional to the number of turns, thus is divided by 2 with 2 turns and by 4 with 4 turns. 

## **Definition of typical, minimum and maximum values** 

Minimum and maximum values for specified limiting and safety conditions have to be understood as such as well as values shown in “typical” graphs. 

On the other hand, measured values are part of a statistical distribution that can be specified by an interval with upper and lower limits and a probability for measured values to lie within this interval. 

Unless otherwise stated (e.g. “100 % tested”), the LEM definition for such intervals designated with “min” and “max” is that the probability for values of samples to lie in this interval is 99.73 %. 

For a normal (Gaussian) distribution, this corresponds to an interval between −3 sigma and +3 sigma. If “typical” values are not obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to an interval between −sigma and +sigma for a normal distribution. 

Typical, maximal and minimal values are determined during the initial characterization of the product. 

## **Remark** 

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.**

## **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 (e.g. primary bus bar, 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.
