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 208 V to 240 V: Appendix B
• North America 380 V to 500 V: Appendix B
• All other International 380 V to 600 V: Appendix B
Line (Mains) and motor cable installation
The input line and motor cables must be sized in accordance
with the rated PowerXL 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 100,000 A RMS for
all size PowerXL VFDs.
Input protection
Input protection devices are rated based on PowerXL rated
input and output current. For UL and cUL/CSA, refer to
AppendixD for proper sizing. For gG/gL (IEC 60269-1), refer
to Appendix B for proper sizing.
Consult with service representative for further information
about input protection requirements.
Brake chopper connection
Dynamic braking resistor connections are made to the R+
and R- terminal on the drive. Wire size should be followed
according to the wattage being transfered. Below are images
of the locations for wiring.
