îš„Interrupting Rating
Varispeed F7 is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 VAC maximum (200 V Class) and 480 VAC maximum (400 V Class).
Use a circuit breaker or fuses having an interrupting rating not less than 100,000 RMS symmetrical amperes,
600 VAC maximum.
îš„Motor Overheat Protection
To protect the motor from overheating, set the E2-01 constant in the Inverter to the same value as the level of
the motor rated current.
