Safety
This transducer must be used in electric/electronic equipment with respect to
applicable standards and safety requirements in accordance with the following
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.
