Page 17: Mounting
CT-600/CT-1000 User’s Manual 2.4 Mounting The current transducers can be mounted in different configurations, depending on user’s needs and opportunities, but heatsink shall never be faced to the floor. The transducers are designed to be used in rack-mount applications, by means of any of the two (2) different 4-hole patterns placed in different sides of the mechanical case. -
Page 18: Primary Current Path
CT-600/CT-1000 User’s Manual • UNI 8119 • DIN 7504 - P • ISO 15482 2.5 Primary Current Path A non-symmetrical layout of the primary current return path may degrade the accuracy and the noise of the current transducer. A cross section of the transducer plastic case illustrates what happens if the primary current is not equally distributed over the perimeter of the current transducer head. -
