Wire sets for use with the reduced run function

A "reduced run" function (for inverter unit frame sizes 3×R8i and above) makes it possible
to continue operation with limited current even if some modules of the inverter unit are out
of service. For more information, see chapter
STO connection is available as shown below.

DC-side components


Frame R8i modules are connected to the DC bus through fuses. The design presented in
this manual has flush-end fuse blocks bolted to the DC busbars.
A DC switch/disconnector can be installed if quick isolation of the module from the DC bus
is required. One of the auxiliary contacts of the switch is used for monitoring the
open/closed state of the switch. A capacitor charging circuit is to be installed with the DC
switch/disconnector.
Note: A separate capacitor charging circuit must be designed and installed by the
customer if the inverter unit is directly connected to the DC bus and the supply unit of the
system does not have a charging capability.
The common mode filters (see page 257) are mounted onto the busbars that connect to
the DC input of the inverter module.

DC bus installation parts (for Rittal TS 8 enclosures)

The brackets in this kit act as a mounting base for the busbar supports of the Rittal Flat-
PLS DC bus and ensure its correct placement and alignment inside the cabinet line-up.
Note: The designs presented in this manual for Rittal TS 8 enclosures employ the Rittal
Flat-PLS busbar system. Make sure that the current carrying capability of the busbars is
not exceeded at any point of the drive system.
