Description:

The inverter unit can be connected to the DC bus through either fuses only or a switch fuse.

Fitting a switch fuse enables the isolation and reconnection of an inverter module even when the DC bus is energised. On the other hand, an external circuit is required for controlled charging of the capacitor bank of the module when the switch fuse is closed. For frame R2i to R5i inverter modules, only the DC fuses are required in addition to the switch fuse kit since the modules contain an internal charging circuit. R6i, R7i and R8i (and multiples) inverter units require the switch fuse kit, DC fuses, and fuses for the charging circuit. The tables below specify the DC fuses, DC fuse bases, switch fuse kits, and charging circuit fuses for the ACS800-104 inverter units.
