Safety and warning notes

In order to guarantee safe operation of the transducer and to be able to make

proper use of all features and functions, please read these instructions thoroughly!

Safe operation can only be guaranteed if the transducer is used for the purpose

it has been designed for and within the limits of the technical specifications.

Ensure you get up-to-date technical information that can be found in the latest

associated datasheet under www.lem.com.

Caution! Risk of danger

Ignoring the warnings can lead to serious injury and/or cause damage!

The electric measuring transducer may only be installed and put into

operation by qualified personnel that have received an appropriate training.

The corresponding national regulations shall be observed during

installation and operation of the transducer and any electrical conductor.

The transducer shall be used in electric/electronic equipment with respect

to applicable standards and safety requirements and in accordance with all

the related systems and components manufacturers’ operating instructions.

Caution! Risk of electrical shock

When operating the transducer, certain parts of the module may carry

hazardous live voltage (e.g. primary conductor). The user shall ensure

to take all measures necessary to protect against electrical shock. The

transducer is a build-in device containing conducting parts that shall not be

accessible after installation. A protective enclosure or additional insulation

barrier may be necessary. Installation and maintenance shall be done with

the main power supply disconnected except if there are no hazardous live

parts in or in close proximity to the system and if the applicable national

regulations are fully observed.

Safe and trouble-free operation of this transducer can only be guaranteed if transport,

storage and installation are carried out correctly and operation and maintenance are

carried out with care.
