TYPICAL FLOATING CONTROL (wiring diagrams)
Figure-2 through Figure-5 illustrate typical wiring diagrams for MFx1-7203 Series spring
return floating actuators. See Table-1 for model selection.
Caution: This product contains a half-wave rectifier power supply and must not be
powered off transformers used to power other devices utilizing non-isolated full-wave
rectifier power supplies. Refer to
EN-206, Guidelines for Power Multiple Devices from a
Common Transformer, F-26363 for detailed information.
