24 V Control Circuit Supply - ABB MicroFlex e150 User Manual

24 V control circuit supply

A 24 V DC supply must be provided to power the controlling electronics. This is
useful for safety reasons where AC power is removed from the power stage, but the
controlling electronics must remain powered to retain position and I/O information.
A separate fused 24 V supply should be provided for the MicroFlex e150. If other
devices are powered from the same 24 V supply, a filter (part FI0014A00) should be
installed to isolate the MicroFlex e150 from the rest of the system. Alternatively, a
ferrite sleeve can be attached to the supply cable near connector X2.
