Safety
This transducer must be used in limited-energy secondary circuits according to
IEC 61010-1.
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 build-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.
