**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 breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements. 

**Cau琀椀on:** When using insulated wires all wiring must be insulated for the highest voltage used.

**Advanced Sensor Protection Circuits “ASPC”** 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) 

## **Status pins** 

When transducer is operating in normal condition, the status pins (3 and 8) are shorted. Status pins properties:     - forward direction pin 8 to pin 3, maximum forward current 10mA 

- maximum forward voltage 60V, maximum reverse voltage 5V 

## **Accessories** 

- 4-channel power supplies unit for connection up to 4 x DL2000 : 

- 6-channel power supplies for connection of up to 6 x DL2000: 

- Transducer cables in 4 lengths (2m - 5m - 10m –15m - 20m): 

DSSIU-4-1U DSSIU-6-1U DSUB2 - DSUB5 - DSUB10  - DSUB15 - DSUB20

**DS300UB-10V** 

## **Intended use:** 

The DS300UB-10V is designed to measure current up to 300A, 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 each sensor 

7. Connect a Voltmeter, DMM or other sort of analyzer with a voltage input to the transducer BNC connector. 

8. Ensure that no calibration connectors are attached when measuring primary current. Always avoid to create a calibration short circuit, between + and — calibration connection. 

9. There is a risk of electrical shock if an uninsulated busbar with high voltages is touching the metal enclosure of the transducer. Please ensure before powering up the system that no primary busbar can touch the metal enclosure. 

10. When all connection are secured - connect mains power 

11. Apply primary current 

## **Safety Instructions:** 

DO NOT TRY TO DISASSEMBLE THE UNIT. 

If the  green transducer diode is not operating when the system is powered up, disconnect power and contact Danisense for further instruction. 

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
