Applications examples
According to EN 50178 and IEC 61010-1 standards and following conditions:
●Over voltage category OV 3
●Pollution degree PD2
● Non-uniformeld
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.
