Power Wiring Selection - Emerson EVH Series Installation Manual

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
o North America 208 V to 240 V: Page 22
o North America 380 V to 500 V: Page 24
o All other International 380 V to 600 V: Page 25
Line (Mains) and motor cable installation
The input line and motor cables must be sized in
accordance with the rated EVH drive 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 EVH Drives.
Input protection
Input protection devices are rated based on the EVH drive
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 transferred. Below are
images of the locations for wiring.
