Section 5
Auxiliary Input and Output Power Option Devices
A disconnect device (circuit breaker, contactor, disconnect switch, etc.) should NOT be used as a means of starting and stop-
ping the Drive or motor.
A disconnect device can be installed for emergency stop purposes, but when that disconnect device is opened, there may be
loss of electrical braking.
Figure 1-3 is a factory guideline for proper wiring practices and relative locations within the electrical path from the line to the
load. It does not imply what devices are needed for a particular application, nor does it show what devices were shipped with
a particular order. Therefore, disregard those items in the diagram which are not being used in your installation. However, it is
recommended that an input or DC reactor be used with all Drive ratings when wired to a source of 600 kVA or greater. Mount
all optional power devices close to the Drive, and keep electrical connections as short as possible.
Note: DO NOT run input and output wiring in the same conduit.
