Product Overview

4.4 Internal Components

The drive system is designed by the installer to meet specified power requirements, using the VLT
basic kit and any selected options kits. The basic kit consists of connecting hardware and either 2 or 4 drive modules, which
are connected in parallel.
The basic kit contains the following components:
•
Drive modules

•
DC fuses
•
Microswitches
Other components, such as busbar kits and back-channel cooling duct kits, are available as options to customize the drive
system.
The drive system in Illustration 4.4 shows a system using 4 drive modules. A system using 2 drive modules is similar, except
for the connecting hardware used. The illustrated drive system shows the cooling kit and the busbar option kit. However,
the installer can use other connection methods, including custom manufactured busbars or electrical cables.
NOTICE
The installer is responsible for the details of the drive system construction, including connections. Also, if the installer
does not use the Danfoss recommended design, the installer must obtain separate regulatory approvals.
