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.
This device is not intended for outdoor use.
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.
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.
Although LEM applies utmost care to facilitate compliance of end products with applicable regulations during LEM product
design, use of this part may need additional measures on the application side for compliance with regulations regarding EMC and
protection against electric shock. Therefore LEM cannot be held liable for any potential hazards, damages, injuries or loss of life
resulting from the use of this product.
Compliance with EU directives.

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.
