Safety

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 built-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.
