DC-side components
Frame R1i...R4i inverter modules are connected to the DC bus through individual fuses.
The fuses are installed on fuse bases that can be opened under no load. Microswitches are
used for monitoring the open/closed state of the fuse bases. The fuse bases specified for
frame sizes R3i and R4i include the microswitches as standard; the microswitches must be
ordered separately for R1i and R2i fuse bases.
A main DC switch/disconnector and DC fuses for all the modules in the same enclosure
can optionally be added. The main DC fuses are typically used to protect against short-circuits
in the DC path to the module fuses when a high-power supply unit is used.
