## **Intended use** 

� To ensure safety protection, only use the device as described by the manufacturer 

The DSSIU-1 is designed to power current transducers such as Danisense DT, DS, DQ, DN and DM series or similar. Please see the product manual: https://danisense.com/user-manual. 

- Cleaning only with a damp cloth 

- Power/unpower the device by plugging/unplugging the mains power cord 

- Always keep mains power cord accessible 

## **Connections** 

- (Front) D-sub-9 connector for connecting the transducer cable with the DSSIU-1 

- (Front) RED 4 mm banana connector for connecting the positive (+) current or voltage reading from the transducer 

- (Front) BLACK 4 mm banana connector for connecting the negative (-) current or voltage reading from the transducer 

- (back) 3 pole IEC mains power connector 

- (back) 4 pin connector to read STATUS and TEDS signals fed through from the transducer 

## **Instruction for use** 

1. Do not power up the device before all cables are connected.

**DSSIU-1** 

2. Place the primary conductor through the aperture of the transducer. 

3. Connect a D-sub-9 cable between DSSIU-1 and sensor. 

4. Connect a low impedance amperemeter, measuring resistor or power analyzer on the output (4mm red and black connectors). 

5. If using a transducer with direct measuremnent output from the transducer housing (DS600UB-10V or similar), AVOID connecting to the black and red bananas on the front of the DSSIU-1. 

6. When all connection are secured - connect mains power. 

7. Apply primary current. 

## **LEDs** 

The two front panel LEDs indicate 1) the DSSIU-1 is powered. 2) the status signal (if available) from the connected transducer is OK.

When the sensor is operating in normal condition the status pins (Status+ and Status-) are shorted by an optocoupler and the green status LED is ON, see Fig. 2. When a fault is detected, or the power is off, the status pins are opened and the green status LED is OFF. Status signal optocoupler ratings found below:
