4.2 Terminal rating Inputs 
 
Mains voltage: Input current depending on the operating state of the unit 
Under voltage  U
Mains 120 V  UMains 230 V 
  Safety shutdown from the operating 
position takes place should mains 
voltage drop 
≤AC 75 V  ≤AC 165 V 
  Restart is initiated when mains 
voltage exceeds 
≥AC 100 V  ≥AC 195 V 
State inputs, temperature controller, temperature switch, load controller, pressure 
switch, air pressure switch, actuator (except safety loop) of the contact feedback 
network (CFN) are used for system supervision and require mains-related input
