Safety
guidelines
To avoid possible personal injury whenever you are working
with the 6430 unit:
•
Do not operate the drive without the motor case tied to
earth ground.
Note: This is normally done by connecting the motor’s case
to J3-5 of the 6430 and connecting J1-3 of the 6430 to earth
ground. These pins are marked by a
symbol on the
silkscreen and are shown on the diagram on page 2-4.
•
Do not make any connections to the internal circuitry. The
input and output signals are the only safe connection
points.
•
Always remove power before making or removing
connections from the unit.
•
Be careful of the J3 motor terminals when disconnected
from the motor. With the motor disconnected and power
applied to the drive, these terminals have high voltage
present, even with the motor disconnected.
•
Do not use the ENABLE input as a safety shutdown.
Always remove power to the drive for a safety shutdown.
