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. The wire set for the 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 are mounted onto the busbars that connect to the DC input of the
inverter module.
