20 SAC01 AC CURRENT SENSOR Instruction of Installation and Use

Caution: 1. Pay attention to the auxiliary power information, especially the auxiliary power grade, and polarity, other wise will damage the product. 2. Pay attention to the wire connection; wrong terminal connection will cause malfunction of the product and even damage the product; 3. Don’t dismantle the product, and carry with care to avoiding bump and fall of the product; 4. If the product has been using under the environment with strong magnetic field interference, please pay attention to the shield of input wire, and the output signal wire should be as short as possible. For product intensive installation, the space between each product should not be smaller than 10mm. 5. Only use identified terminals. 6. There is no lightening strike prevention circuit design in this product. For out door and hazardous environment using, please add protective alternatives. 7. This product uses fire prevent ABS crust, its temperature withstand is only limited as +85°C, higher than this limitation will cause the product deformation. Please use and store carefully.

1. The product has compliance with EN50022; suitable for DIN rail mounting NS35/7.5, NS35/15. Installation steps are as following (please reference to dimensional drawing): Step 1: Immobilize one side of product‘s mounting trough to the DIN mounting rail; Step 2: Pull out the spring clasp; Step 3: Place whole mounting trough to the DIN mounting rail properly; Step 4: Release spring clasp to make sure the installation. 2. The product has calibrated before out of factory. After correctly wiring, it can be powered and used immediately. But for further precise signal sampling, user needs to warm-up the product for 3 minutes before use. a) The auxiliary power requires isolation voltage≥2000VAC, DC current output ripple <10mV, and multiple converters can share with one set auxiliary power together. b) Output signal (hz) is designed to follow the impedance load value of 250Ω; When Resistance (R1 ) is less than 100Ω, the user must add output current circuit a power reduced resistance load R0 to keep the summation of total impedance value is between 100Ω~ 250Ω.

3. The Maximum volume of line for the transducer terminal is 2.5mm 2 ; the insulation layer of the line should be peeled off about 8mm~10mm and tightly twisted to connect with the transducer terminals. 4. For the less than 10A AC current measurement, it may adopt ampere-turn method for input and for this time, the resolution of the transducer increases and measuring range narrows, but other technical index may not be affected.
