Notes:
Can be any UL listed type with below ratings.
Due to UL listing, only can be below Eaton types.
Line and motor cable size is selected according to UL 61800-5-1 for copper conductor rated 75°C. Use only with copper wire rated 75°C here. Size requirements for
other different wire types are defined in the National Electrical Code
®
, ANSI/NFPA
®
70.
Earthing conductor size is determined by the maximum overcurrent device rating used ahead of the drive according to UL 61800-5-1.
n If power cubes or bypass are used, a UL listed Class J, T, CF, CC or equivalent fuse is recommended.
Refer to Appendix B for specific branch circuit protection devices types recommended by Eaton.
