Remarks • VOUT is positive when IP flows from terminals 1, 7 (IN) to terminals 2, 8 (OUT) • Temperature of the primary conductors should not exceed 100°C. 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 built-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.
