3.4.8 24Vcontrol circuit supply
A24VDC supplymust be provided to power thecontrolling electronics . This is useful for safety
reasons where AC power needs to be removed from the power stage but the controlling
electronics must remain powered to retain position and I/O information.
A separate fused 24V supply should be prov ided for the MicroFlex e100. If other devices are
likely to be powered from the same 24V supply, a filter (Baldor catalog number FI0014A 00)
should be installed to isolate the MicroFlex e100 from the rest of the s ystem. Alternatively, a
ferrites leeve may be attached to the supply cable near connector X2.
