Appendix 4 Instructions for UL and cUL

(Conforming standard UL 508C, CSA C22.2 No.14)
(1) Installation
This inverter is UL-listed as a product for use in an enclosure.
Design an enclosure so that the inverter ambient temperature, humidity and atmosphere satisfy the specifications.
(Refer to page 92.)
Wiring protection
For installation in the United States, branch circuit protection must be provided in accordance with the National
Electrical Code and any applicable provincial codes.
For installation in Canada, branch circuit protection must be provided in accordance with the Canada Electrical

(2) Wiring of the power supply and motor
For wiring the input (R/L1, S/L2, T/L3) and output (U, V, W) terminals of the inverter, use the UL-listed copper wires
(rated at 75°C(167°F)) and round crimping terminals. Crimp the crimping terminals with the crimping tool
recommended by the terminal maker.
(3) Short circuit ratings
• 200V class
Suitable For Use in A Circuit Capable Of Delivering Not More Than 65kA rms Symmetrical Amperes, 264V
Maximum.
• 400V class
01160 or less
Suitable For Use in A Circuit Capable Of Delivering Not More Than 65kA rms Symmetrical Amperes, 528V
Maximum.
01800 or more
Suitable For Use in A Circuit Capable Of Delivering Not More Than 65kA rms Symmetrical Amperes, 550V
