## **Safety** 

⚠ Caution 

If the device is used in a way that is not specified by the manufacturer, the protection provided by the device may be compromised. Always inspect the electronics unit and connecting cable before using this product and do not use it if damaged. Mounting assembly shall guarantee the maximum primary conductor temperature, fulfill clearance and creepage distance, minimize electric and magnetic coupling, and unless otherwise specified can be mounted in any orientation. 

Caution, risk of electrical shock 

This transducer must be used in limited-energy secondary circuits SELV according to IEC 61010-1, in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturer’s operating specifications. 

Use caution during installation and use of this product; certain parts of the module can carry hazardous voltages and high currents (e.g. power supply, primary conductor). 

Ignoring this warning can lead to injury and or/or cause serious damage. 

De-energize all circuits and hazardous live parts before installing the product. 

All installations, maintenance, servicing operations and use must be carried out by trained and qualified personnel practicing applicable safety precautions. 

This transducer is a build-in device, whose hazardous live parts must be inaccessible after installation. This transducer must be mounted in a suitable end-enclosure. 

Besides make sure to have a distance of minimum 30 mm between the primary terminals of the transducer and other neighboring components. 

## Main supply must be able to be disconnected. 

Always inspect the flexible probe for damage before using this product. 

Never connect or disconnect the external power supply while the primary circuit is connected to live parts. Never connect the output to any equipment with a common mode voltage to earth greater than 30 V. 

Always wear protective clothing and gloves if hazardous live parts are present in the installation where the measurement is carried out. 

This transducer is a built-in device, not intended to be cleaned with any product. Nevertheless if the user must implement cleaning or washing process, validation of the cleaning program has to be done by himself. When defining soldering process, please use no cleaning process only. 

## ESD susceptibility 

The product is susceptible to be damaged from an ESD event and the personnel should be grounded when handling it. 

Do not dispose of this product as unsorted municipal waste. Contact a qualified recycler for disposal.

**HO 50 ... 250-S** 

## **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.

**HO 50 ... 250-S** 

## **Application information** 

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

- ●Use of a bare conductor is not recommended with panel mounting (either horizontal or vertical) as insulation distances might be compromised between the busbar and fixation screws. 

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

|**nsulation 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|



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 

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

## **Remarks:** 

- _U_ out is positive with respect to _U_ ref when positive _I_ P flows in direction of the arrow shown on the drawing above. 

- ●Connection system: equivalent to JST B5B-PH type 

- ●Mounting foot may be removed and repositioned as shown on pages 16,17 and 18 of this datasheet. We recommend to change the mounting foot position just once.
