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.

Temperature of the primary conductor should not exceed 100C. Dynamic performances (di/dt and response time) are best with a single bar completely filling 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.
