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.
Installation and maintenance should be done with main power supply
disconnected.
The operator must have an accreditation to install this material.
Caution! Risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (e.g. primary conductor, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
The user must take care of all protection guarantee against electrical shock.
This transducer is a built-in device, whose conducting parts must be inaccessible
after installation. A protective housing or additional shield could be used.
