Remarks Caution, risk of electrical shock * IS is positive when IP flows in the direction of the arrow. * Temperature of the primary conductor should not exceed 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. 100C. 060911/3 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
