1) Three-phase connection requires a commutating choke.
2) Mains current with relative mains impedance ≥ 1% (see chapter „Electrical
installation“) 3) Reduction of switching frequency in thermal limit range
6) For UL-compliant fusing, the specified Cooper Bussmann fuses must be used. Other
fuses must not be used for UL-conforming fusing.
