Instruction for use: 1.Do not power up the device before all cables are connected. 2.Only use cable provided by Danisense to ensure correct wiring and dimension of cable. 3.Ensure that it is easy to unplug the mains cord in case of system problems. 4.Place the primary conductor through the apperture of the transducer(s) 5.If the DSSIU-4-1U is intended for desk use, mount the rubber feet which are part of the package. 6.If the DSSIU-4-1U is intended for Rack mounting, use the screw kit for mounting and do not mount the rubber feet. 7.Connect a Danisense DSUB cable between DSSIU-4-1U and each sensor 8.Connect a low impedance amperemeter, measuring resistor or power analyzer on the secondary output (4mm red and black connectors) 9.Ensure that no calibration connectors are attached when measuring primary current. Always avoid to create a calibration short circuit, between + and — calibration connection. 10.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. 11.When all connection are secured - connect mains power with the mains cable delivered. If other cables are used ensure that the cable has sufficint rating for operation. 12.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 equipment may be impaired.. It is mandatory to support the unit when rack mounted, either on the sides or backside. Indications: When mains is applied the left light diode on the front under the power symbol will light green. For each sensor channel connected a green light diode will light on the front if the connection is correct and the sensor is operating within normal range. page 5 - 2021-03-04 Precision – Innovation www.danisense.com DSSIU-4-1U Declaration of Conformity Danisense A/S Malervej 10 DK-2630 Taastrup Denmark Declares that under our sole responsibility that this DSSIU-4-1U is in conformity with the provisions of the following EC Directives, including all amendments, and with national legislation implementing these directives: Directive 2004/108/EC, Class A+B And that the following harmonized standards have been applied EN/IEC 61010-1 (Third Edition):2010, EN 61010-1:2010 Declares that under our sole responsibility that all products delivered by Danisense are manufactured in accordance with RoHS directive 2015/863/EU.
