Interrupting Rating
WARNING! Fire Hazard. This product requires installation of Branch Circuit Protection (BCP) as defined in
NFPA 70 of the National Electrical Code, Article 430, Section IV, Paragraph 430.52. Failure to comply may
result in injury to personnel from fire.(Table 10.2).
The G7 drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 Vac (200 V class) and 480 Vac (400 V class), when protected by branch circuit protection
devices specified in this manual. Use a circuit breaker or fuses having an interrupting rating not less than
100,000 RMS symmetrical amperes, 600 VAC maximum.
 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.
