DS300UB-1V Intended use: The DS300UB-1V is designed to measure current up to 450A, and be powered by a DSSIU-4-1U or DSSIU-6-1U. Instruction for use: 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...
