Conditions of acceptability
When installed in the end-use equipment, consideration shall be given to the following:
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 have been evaluated for use in 105°C maximum surrounding air temperature.
5 - The secondary (Sensing) circuit is intended to be supplied by a Isolated Secondary Circuit - Limited voltage circuit defined
by UL 508 paragraph 32.5. The maximum open circuit voltage potential available to the circuit and overcurrent protection
shall be evaluated in the end use application.
6 - These devices are intended to be mounted on a printed wiring board of end-use equipment. The suitability of the connec-
tions (including spacings) shall be determined in the end-use application.
7 - Primary terminals shall not be straightened since assembly of housing case depends upon bending of the terminals.
8 - Any surface of polymeric housing have not been evaluated as insulating barrier.
9 - Low voltage circuits are intended to be powered by a circuit derived from an isolating source (such as a transformer, optical
isolator, limiting impedance or electro-mechanical relay) and having no direct connection back to the primary circuit (other
than through the grounding means).
Marking
Only those products bearing the UL or 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.

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 a 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.
