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 Connection Top view Mechanical characteristics Remarks • General tolerance • Transducer fastening • IS is positive when IP flows in the direction of the arrow. • Temperature of the primary conductor should not exceed ± 0.5 mm 2 holes ∅ 5.3 mm 2 M5 steel screws Recommended fastening torque 4 Nm or 2.96 Lb. - Ft. or 4 holes ∅ 4.2 mm 4 M4 steel screws Recommended fastening torque 3.2 Nm or 2.37 Lb. - Ft. or 4 holes ∅ 2.25 mm depth10 mm 4 x PT KA30 screws long 10 mm Recommended fastening torque 0.9 Nm or 0.66 Lb. - Ft. • Transducer fastening Horizontal position 4 holes ∅ 5.3 mm 4 M5 steel screws Recommended fastening torque 4 Nm or 2.96 Lb. - Ft. or 4 holes ∅ 2.25 mm depth16 mm 4 x PT KA30 screws long 16 mm Fastening torque, maxi 1 Nm or 0.74 Lb. - Ft. • Primary through-hole 40.5 x 13 mm or ∅ 38 mm • Connection of secondary Molex 5045-03/A Vertical position 100°C. • Dynamic performances (di/dt and response time) are best with a single bar completely filling the primary hole. • This is a standard model.
