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. page 2/3 060821/7 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice. w w w .lem.com Dimensions LF 1005-S (in mm. 1 mm = 0.0394 inch) Bottom view Back view Front view Top view Connection Mechanical characteristics * General tolerance * Transducer fastening Vertical position 0.5 mm Remarks * IS is positive when IP flows in the direction of the arrow. * Temperature of the primary conductor should not exceed * Dynamic performances (di/dt and response time) are best * This is a standard model.
