(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 93.)
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
Code and any applicable provincial codes.
Use the Class RK5, Class T or L type fuses certified by UL and cUL.
(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) 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
55K or less
Suitable For Use in A Circuit Capable Of Delivering Not More Than 65kA rms Symmetrical Amperes, 528V Maximum.
75K or more
Suitable For Use in A Circuit Capable Of Delivering Not More Than 65kA rms Symmetrical Amperes, 550V Maximum.
(4) Motor overload protection
When using the electronic thermal relay function as motor overload protection, set the rated motor current to Pr.9
Electronic thermal O/L relay.
When connecting multiple motors to the inverter, install an external thermal relay individually.
