WARNING! Fire Hazard. Install adequate branch circuit protection according to applicable local codes and
this manual (Table 10.2). Failure to comply could result in fire and damage to the drive or injury to personnel.
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.
