Frame size R8i inverter modules are connected to the drive DC bus
through a switch fuse (type OESL by ABB). The installation is
equipped with a Switch Fuse Controller Unit (ASFC) which controls
the inverter power switch-on and power switch-off. The unit also
protects the charging circuitry by stopping the inverter if switch fuse is
accidentally opened while the inverter is running.
One switch fuse (controlled by one ASFC unit) can provide power
supply for one to three inverter modules. Every inverter module must
have a charging circuit of its own.
The ASFC unit consists of the ASFC board enclosed into a plastic
housing (IP00). The unit can be snapped on onto a standard mounting
rail.
