1 General About the IR5002 With the insulation monitoring device IR5002, BENDER offers a special equipment for continuous monitoring of the insulation resistance of IT DC systems to earth. The device is intended to indicate when the value falls below a preset response value. -
Page 5: The Concept Of Ir5002
That provides adequate safety of the IR5002 and the connected peripheral devices. IR5002 can be used as an independent device or in combination with the Coupling device coupling device AG5002. If response values below 1000 Ω are to be set, the use AG5002 of a coupling device AG5002 will be necessary. -

Page 9: Principle Of Operation
3 Principle of operation IR5002 uses the measuring principle "3-Voltmeter-Method". Asymmetrical as well as symmetrical insulation faults in IT DC systems can be detected according to this measuring principle. In combination with the microcontroller a fast, safe and exact measurement and evaluation can be realized. -
Page 10: Symmetrical And Asymmetrical Insulation Faults
Principle of operation The insulation resistances RF+ and RF- can be calculated according to the following equations: • for symmetrical coupling, i.e R1=R2 and Rm1=Rm2 x Rm1 - (U1+U2) x R2) x Rm2 - (U1+U2) x R1) • for asymmetrical coupling, i.e. relation AK+ / AK- = 2:1 x Rm1 x (U x Rm2 - R2 x (U1 + U2))) (U2 x (U... -

- Page 28 Wiring and commissioning Important note: to fulfil the EMC requirements it is necessary to mount ferrite cores to the wires for the supply voltage and the earth wires. The bigger ferrit core is for the power supply (terminals L1/L+ and N/L-), the smaller ferrit core is for the earth wires PE and PE2.

Page 29: Error Messages
Wiring and commissioning Error messages Various error messages may occur during operation. Error messages are indications of internal or external faults of the IR5002 excluding the response of the device when the pre-set response value of the insulation resistance has been exceeded. -
Page 30: System Errors, Critical Errors
If one or more CRITICAL ERRORS occur, the relay K3 energizes and the CRITICAL ERRORS corresponding error (system error) will be displayed. IR5002 interrupts its measurements when a CRITICAL ERROR occurs. The error code will be output via both serial interfaces. -
Page 31: Indication Of Asymmetrical Faults
Wiring and commissioning Indication of The chapter FUNCTIONAL PRINCIPLE already refers to the fact that asymmetrical symmetrical and asymmetrical insulation faults have to be considered separately. faults In particular, asymmetrical faults have to be considered. If the ratio between the higher and the lower insulation value is greater than 50, the measured value for the higher insulation resistance insulation will not be displayed directly. -
Page 32: Data Output
Data output Data determined by measuring and calculating are output via the interfaces RS 232 and RS 485. By means of appropriate programs (e.g. ISODATA for IR5002) data can be indicated and evaluated. The following values are available via both serial interfaces:... -
