dani/enseIsolation specifications Parameter Caution: Do not connect the transducer to signals or use for measurements within Measurement Category IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without...

dani/enseEnvironmental, safety and mechanical specifications Parameter Developed to protect the current transducer from typical fault conditions: • Unit is un-powered and secondary circuit is open or closed • Unit is powered and secondary circuit is open or interrupted Both DC and AC primary current up to 100% of nominal value can be applied to the current transducers in the above situations without damage to the electronics. Please notice that the transducer core can be magnetized in all above cases, leading to a small change in output offset current (less than 10ppm) When transducer is operating...

dani/enseIntended use: The DS300UB-10V is designed to measure current up to 300A, and be powered by a DSSIU-4-1U or DSSIU-6-1U. 1. Do not power up the device before all cables are connected. 2. Only use cables supplied by Danisense 3. Place the primary conductor through the apperture of the transducer 4. If the DSSIU-4(6)-1U is intended for desk use, mount the rubber feet which are part of the package. 5. If the DSSIU-4(6)-1U is intended for Rack mounting, use the screw kit for mounting and do not mount the rubber feet. 6. Connect a DSUB cable between DSSIU-4(6)-1U and each sensor 7. Connect...
