Motor Cable Connection Procedure; Removing The Fan Carriage Of An Inverter Module - ABB ACS880-107 Hardware Manual

74 Electrical installation
more than three inverter modules, make sure that the load is distributed evenly between
the modules:
•
In case of two inverter cubicles of two modules, connect the same number of cables to
each cubicle.
•
In case of one inverter cubicle with three modules and another with two, each cubicle
requires a number of cables proportional to the number of modules within. For
example, connect three out of five (or six out of ten, etc.) cables to the cubicle with
three modules, the remaining two out of five (four out of ten) cables to the cubicle with
two modules.

Motor cable connection procedure


The procedure involves removing the fan carriages of each inverter module, making the
connections, and reinserting the fan carriages.
To allow more room for making the connections, the inverter modules can be removed
completely instead of just the fan carriages. To do this, follow the procedure under
Removing the inverter module(s)
