Mount the Kinetix 5700 Drive System Chapter 3
Mount Accessory Modules
Mount the 2198-CAPMOD-2240 capacitor module on the far right or far left
of any system cluster, depending on the input power configuration. A capacitor
module is required in the following situations:
• Required in each cluster of a multi-cluster system
• More than one capacitor module can be used in a cluster, if needed
The 2198-CAPMOD-DCBUS-IO extension module is always mounted next
to a capacitor module or DC-bus conditioner module and always positioned
on the outside of the system cluster (either first or last). The extension module
can be paired with another accessory module and flexible bus-bars if external
DC-bus current is ≥104 A up to a maximum of 208 A.
Figure 47 - Flexible Bus Bar Example
IMPORTANT Each additional capacitor module adds to the total system capacitance and
increased energy storage.
IMPORTANT When the extension module is mounted next to another accessory module,
they must be connected by flexible bus bars.

IMPORTANT In a multi-cluster system with a power supply rated ≥104 A, two accessory
modules connected by flexible bus bars must be used to create a 208 A
extended cluster system. See the Accessory Module Connector Specifications
table on page 181
for DC-bus wiring requirements.
