Figure 4.12 Terminal Diagram
Long control cables and analog signals may result in 50/60
Hz ground loops due to noise from line power supply
cables.
If ground loops occur, break the shield or insert a 100 nF
capacitor between shield and chassis, if needed.

Connect the digital and analog inputs and outputs to the
control cards of the units separately to avoid ground
currents. These connections are on terminals 20, 55, and 39
for both the filter and adjustable frequency drive sections.
