Connection Diagrams
The layout of connection terminals is similar for all frame sizes (R1
…
R6). The only
significant layout difference is in the power and ground terminals for frame sizes R5
and R6. The following diagrams show:
•
Terminal layout for frame size R3, which, in general, applies to all frame sizes
except as noted above.
•
Power and ground terminal layout for frame sizes R5 and R6.
Warning! For floating (ungrounded) networks remove screws at EM1 and EM3.
