NOTE!
The digital outputs of the CFW900-IOS have freewheeling diodes for the 24 Vdc power supply of
the inverter control (inverter internal power supply or external power supply connected to VIN). If a
separate external 24 Vdc power supply is used to power the loads of the digital outputs, the state of
the outputs will remain indeterminate as long as the 24 V power supply of the inverter control is not
energized. If this characteristic is unwanted, the CFW900-REL-01 or CFW900-IOD-01 outputs must
be used.
