*1 In main circuit power supply, voltage should not exceed
230V, + 1 0 % (253V) I f the voltage should exceed this
value, a step down transformer is required
* 2 W h e n housed in a panel, the inside temperature must not
exceed ambient temperature range
* 3 I n the speed control range, the lowest speed is defined
under the condition in with there is 100% load regulation, but
not stopped.
