As safety depends on the relay functioning correctly it is highly recommended that all safety functions of the relay be periodically tested to ensure correct operation. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 9 of 83...
Equipment that is found to be damaged or has been modified away from its published specification must not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or if it does not match the published specifications.
3 PRODUCT OVERVIEW 3.1 IPM V2 Relay The Ampcontrol IPM V2 Integrated Protection Relay is an intelligent protection relay based on microprocessor technology. The IPM Integrated Relay provides the necessary functions required for protecting electrical outlets supplying underground mining machinery, powered by reeling or trailing cables, in the metalliferous industry.

It is extremely important that the limitations and functionality of the relay are understood to prevent incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the nature of the limitations or their implication, consult a competent authority such as a supervisor or Ampcontrol technical representative.
The screws are inserted into the bracket and tightened to secure the IPM to the panel. Figure 4.1: IPM Relay Dimensions Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 17 of 83...
The IPM uses a 1000:1 current transformer installed around all three phases to monitor the earth leakage current of the outlet. These current transformers are panel mounted.

If the IPM is to be installed in areas of high electrical interference, it is recommended that the wiring for the digital inputs be run in screened cables. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 21 of 83...
5. Select the smallest internal diameter CT to suit the cable size. NOTE The two CT-COM terminals (12 & 13) are internally connected and are joined to earth. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 22 of 83...
The earth leakage protection function can be tested by connecting an AC supply through the earth leakage toroid, via a test pushbutton and a resistor. The resistor must be selected to ensure that the earth leakage protection trips as required. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 23 of 83...

The earth connection on the rear of the IPM relay is a bolted connection. An earth conductor should be secured to the chassis of the IPM using a ring lug. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 27 of 83...
5.6 Current Detection in CTs Ensure the integrity of the current-detection CTs by injecting primary current into the CT aperture and validating the reading on the IPM screen. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 28 of 83...
5.11 Lock, Reset, Aux, Ex-Stop, Ex-Start & MCI Inputs Ensure that the digital inputs to the IPM are operating correctly by operating each of the inputs and ensuring that the IPM functions as expected. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 29 of 83...
IPM V2 and assess how the relay‟s performance compares with the requirements of AS/NZS 2081. Testing was completed to assess the ability of the IPM V2 relay to trip within acceptable levels. The results for the earth leakage tripping times of the relay are detailed in APPENDIX 1: IPM Earth Leakage Tripping Curves.
The ITM is the preferred isolation module and must be used when the „Insulation Test‟ function is required. When “None” is selected the IPM Relay does not provide „Insulation Test‟, or voltage functions. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 31 of 83...

The status of the manual insulation test is shown on the Insulation Test Screen (Level 3, Screen 2). The three functions shown on the screen are „Not Active‟, „Arming Man.Ins.Test‟ and „Manual Insulat. Test‟. The display will show the last measured value.

EL current that does not cause a nuisance tripping. Similarly, the earth continuity trip time should be as low as practical to not cause a nuisance trips. In low noise applications (eg: simple DOL motors Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 35 of 83...
Where EC trip settings above 200ms are required to avoid nuisance tripping Ampcontrol recommends the source of noise (and so the electrical distribution system design) is properly investigated to ensure the system is safe.
An emergency restart on a hot motor can be achieved by zeroing the thermal accumulator memory. This is done by closing the Lock input and Reset key/digital input simultaneously for 1.5 seconds. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 37 of 83...
