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. Caution: When using insulated wires all wiring must be insulated for the highest voltage used.

No detergent or chemicals should be used. Temperature Non-condensing 2.0 When multiple primary turns are used or high primary currents are applied the temperature around the transducer will increase, please monitor to ensure that the maximum ratisngs are not exceeded. It is recommended to have minimum 1mm2 per ampere in the primary busbar. 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) Accessories • 4-channel power supplies unit for connection up to 4xDM1200 : DSSIU-4 • 6-channel power supplies unit for connection up to 6xDM1200 : DSSIU-6 • Transducer cables in 5 lengths (2m - 5m - 10m - 15m - 20m): DSUB15 - DSUB20 DSUB2 - DSUB5 - DSUB10 - • Transducer cable 3m for connection to end-user’s power supply: Transducer cable for lab PS (with access to current output via 4 banana jacks) page 5 - 2020-04-27 Precision – Innovation www.danisense.com DM1200ID Dimension in mm (general tolerance 0.3mm unless otherwise stated) Mounting instructions Positive current direction Is identified by an arrow on the transducer body page 6 - 2020-04-27 • Horizontal or vertical mounting Precision – Innovation www.danisense.com 4 holes 6 x 11 4 x M5 steel screws / 6N.m
