For Safe Torque Off installation instructions, refer to the VLT® Frequency Converters -Safe Torque Off Operating Instructions.* Terminal 37 is not included in FC 301 (except enclosure type A1). Relay 2 and terminal 29 have no function in FC 301.** Do not connect cable screen.Very long control cables and analog signals may in rare cases, and depending on installation, result in 50/60 Hz groundloops due to noise from mains supply cables.If 50/60 Hz ground loops occur, consider breaking the shield or insert a 100 nF capacitor between shield and enclosure.To avoid ground currents from both groups to affect other groups, connect the digital and analog inputs and outputsseparately to the common inputs (terminals 20, 55, and 39) of the frequency converter. For example, switching on the digitalinput may disturb the analog input signal.Introduction VLT® AutomationDrive FC 301/3028 Danfoss A/S © 02/2016 All rights reserved. MG33ML0211
