Appendix: Extension modules 415MPOW-01 auxiliary power extension module DescriptionThe MPOW-01 auxiliary power extension module is used in installations where thedrive's control part is required to be powered during network failures andmaintenance interruptions. The MPOW-01 provides auxiliary voltages to the controlpanel, fieldbus and I/O.Note: If you change any of the drive parameters when the drive is poweredthrough the MPOW-01, you have to force parameter saving with parameter 1607PARAM SAVE by setting the value to (1) SAVE…; otherwise all changed datawill be lost. Electrical installationWiring• Use 0.5…1.5 mm2 (20…16 AWG) shielded cable.• Connect the control wires according to the diagram in section Terminaldesignations below. Use a tightening torque of 0.8 N·m (7 lbf·in).Terminal designationsThe diagram below shows the MPOW-01 terminals and how the MPOW-01 module isconnected to the external power supply and how the modules are daisy chained.SCR MPOW-01SCR+ +24 V DC or 24 V AC ± 10%- Terminal SCR is internally connectedto the analog ground (AGND) of thedrive.All terminals are connected togetherinside the module allowing daisychaining of the signals.+-SCRSCRExternalpower supply+GNDSCRNextMPOW-01
