3-14 Basic Installation MN19023.4.7 External customer supplied 24V control supplyDepending on model (catalog numbers FDHxxxxx-xxx3 and FPHxxxxx-xxx3) a 24VDCcontrol supply must be provided to power the control electronics. This is useful for safetyreasons where AC power needs to be removed from the power stage but the controlelectronics must remain powered to retain position and I/O information. It is recommendedthat a separate fused 24V supply is provided for the FlexDriveII. If other devices are likely tobe powered from the same 24V supply then a filter (Baldor catalog number FI0014A00) shouldbe installed to isolate the FlexDriveII from the rest of the system.Location Connector X1 / X1APart number FDHxxxxx-xxx3 or FPHxxxxx-xxx3Nominal inputvoltage24VRange 20.4-28.8VDCInput current(maximum)1.75A continuous (4A power on surge)Tightening torque for terminal block connections is 0.5-0.6Nm (4.4-5.3 lb-in)Note: Connect 24V to connector X1 only if your model has this feature. Connecting 24Vto a model that does not require an external 24V supply (FDHxxxxx-xxx0 andFPHxxxxx-xxx0) could damage the unit.Customer supplied24VDC (fused)+24V24V filter(optional)GNDSingle-phase modelshown for illustrationpurposesSTARPOINTIncoming safetyearth/ground (PE)If 24V wires areshielded,earth/groundouter shields,using 360∫clamps connectedto backplane.Figure 6 - Customer supplied 24V supply connections
