•
The drive is suitable for use on a circuit capable of delivering not more than 65 kA
rms symmetrical amperes at the drive nominal voltage (600 V maximum for
690 V units) when protected by T class fuses.
•
The cables located within the motor circuit must be rated for at least 75 °C
(167 °F) in UL-compliant installations.
•
The input cable must be protected with fuses. Circuit breakers must not be used
without fuses in the USA. Suitable IEC (class aR) fuses and UL (class T) fuses are
