The IM481H requires an external regulated +5Vdc power supply. The supply is connected 
between pins 11 (ground), and 14 (+5vdc). A 22 microfarad 10v tantilum capacitor must 
be placed as close to the IM481H as possible between the +5vdc input pin (14) and 
ground.  
 
The +5vdc supply ground and the motor supply ground should not be connected together 
at the power supplies. The common ground connection between the motor power supply 
and the +5vdc supply should be made at the ground pin of the additional electrolytic 
capacitor used for the motor supply (see section 9.1) 
 
Figure 5 shows the proper connection of the external +5vdc supply to the IM481H. 
 
NOTE: 

Care should be taken when using this supply not to couple noise from 
external circuits into the IM481H which could cause erratic operation or 
damage.
