## **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._ 

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

**HO 50 ... 250-S/SP33 series** 

## **Application information** 

- ●HOxx-S series is designed to use a bus-bar or a cable[1)] to carry the current through out the aperture with a maximum cross section of 8 × 15 mm 

- ●Use of bare conductor is not recommended for panel mounting horizontal or vertical, insulation distance might not be respected between busbar and fixation screw head. 

Note: 1) The maximum magnetic offset referred to primary is inversely proportional to the number of turns, thus is divided by 2 with 2 turns. 

## **Insulation distance (nominal values):** 

|**Insulation distance (nominal values):**|||
|---|---|---|
||_d_Cp|_d_CI|
|Betweenprimarybusbar and secondary pin|14.6 mm|-|
|Betweenprimarybusbar and core|-|11.34 mm|
|Between core and secondaryterminal|-|1.18 mm|



## **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, minimum and maximum 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.
