￭ DC bus connection and capacitor charging
The cabinet installer must equip the converter unit with DC fuses on the DC bus side and
with output DC fuses on the energy storage side. The user must equip also the energy
storage with fuses for protecting the energy storage cable in a cable short-circuit situation.
The user can install a DC switch/disconnector if quick isolation of the module from the DC
bus is required.
