Power Wiring Selection

Motor cable connections are made to terminals U, V, and W.

Cable Selection: Power and Motor Leads

Use UL approved heat-resistant copper cables only
●
75°C or higher for all units rated
●
Line voltage/mains should be Class 1 wire only outside
●
North America
Refer to the following tables for cable sizing guidelines
●
North America 208V to 240V: Appendix B
●
North America 380V to 500V: Appendix B
●
All other International 380V to 600V: Appendix B

Line (Mains) and Motor Cable Installation

The input line and motor cables must be sized in accordance
with the rated DG1 VFD input and output current.
If motor temperature sensing is used for overload protection,
the output cable size may be selected based on the motor
specifications.
Maximum symmetrical supply current is 100,000A RMS for
all size DG1 VFDs.
Input Fusing
Fuses are rated based on DG1 rated input and output
current. Use Class T (UL and cUL/CSA
60269-1). Refer to Appendix B for proper fuse size selection.
Consult with Eaton Electrical for further information on fusing
requirements.
