Appendix D Integrated Protective Maintenance Grounding Device The compact design of the IPMG device does not compromise its rugged construction and proven performance under industrial operating conditions. Requiring minimal maintenance, this manually operated device is controlled from the outside of the standard and arc-resistant (ArcShield™) medium voltage controllers. -
Page 99: Operating Handle
Appendix D Integrated Protective Maintenance Grounding Device Operating Handle IMPORTANT There must be a minimum clearance of 25.5 mm (12 in.) on the side of the cabinet where the operating handle is located. The separate operating handle is suitable for use only for the hex splined interface shaft of the IPMG device. - Page 100 Appendix D Integrated Protective Maintenance Grounding Device Figure 97 - Close the IPMG Device from an Open Position (1512B Cabinet with 400 A IPMG Device) Opening the IPMG Device from a Closed Position 1.

Appendix D Integrated Protective Maintenance Grounding Device The auxiliary contacts are factory adjusted and should not require readjustment in the field. The electrical configuration of the auxiliary contacts is shown below. Figure 100 - Standard, 2- Form C Auxiliary Contact Configuration IPMG Specifications Specifications Description... -
Page 104: Maintenance
Appendix D Integrated Protective Maintenance Grounding Device Maintenance The IPMG device is virtually maintenance free. All contacts are lubricated in the factory at the time of shipment. General annual inspections should include that the main drive line operates smoothly and does not stick or bind due to possible misalignment that is caused by the mechanical interlocks and interfacing to the main contactor and isolation switch. - Page 105 Appendix History of Changes This appendix contains the new or updated information for each revision of this publication.
