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 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.

Remarks
I ●S is positive when IP ows in the direction of the arrow.
Temperature of the primary conductor should not exceed ●
100°C.
Dynamic performances (di/dt and response time) are best ●
with a single bar completely lling the primary hole.
In order to achieve the best magnetic coupling, the ●
primary windings have to be wound over the top edge of
the device.
