• 400V class

Design the enclosure so that the ambient temperature, humidity and ambience of the inverter will satisfy the above specifications. (Refer to page 187)

(2) Branch circuit protection

For installation in United States, branch circuit protection must be provided, in accordance with the National Electrical Code and any applicable local codes.

For installation in Canada, branch circuit protection must be provided in accordance with the Canada Electrical Code and any applicable provincial codes.

(3) Short circuit ratings

•200V class

Suitable For Use in A Circuit Capable of Delivering Not More Than 5 or 10kA rms Symmetrical Amperes, 230 or 500 Volts Maximum.

•400V class

Suitable For Use in A Circuit Capable of Delivering Not More Than 10kA rms Symmetrical Amperes, 500 Volts Maximum.

(4) Wiring of the power supply and motor

Screw the cables wired to the input (R, S, T) <L1, L2, L3> and output (U, V, W) terminals and control circuit of the inverter to the specified tightening torque using UL-recognized, 75° or higher rated copper wires and round crimping terminals. Crimp the crimping terminals with the crimping tool recommended by the terminal maker.
