UL - drive system, configuration example

UL - drive system, configuration example 1:

Drive system with UL approval

The following illustration shows a possible configuration example. Before implementation, please contact your UL certificate authority and discuss further necessary boundary conditions.

Please note that the AX-Bridge does not have UL approval.

UL - drive system, configuration example 2:

Legend:

1 = UL-circuit breaker (480 V AC)

2 = UL circuit breaker (700 V AC / 800 V DC) e.g. Ferrule FWP from Cooper-Bussmann

UL - drive system, configuration example 3:

Fuse holders with UL approval

Note when using UL circuit breakers that the necessary fuse holders also have to carry UL approval.

Dimensioning of the UL circuit breaker (2)

The dimensioning of the fuses (2) in the DC link is application-dependent. The motor and the load profile are directly factored into the calculation; please take this into account during the design process.
