## **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.

Important notice:  whatever the usage and/or application, the transducer jumper temperature shall not go above the maximum ratings of 120 °C as stated in page 2 of this datasheet. 

## **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.

## **Assembly on PCB** 

- ●Recommended PCB hole diameter 1.6 mm for primary pins 1 mm for secondary pins 

- ●Maximum PCB thickness 2.4 mm ●Wave soldering profile maximum 260 °C for 10 s No clean process only. 

## **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.
