and regulations.
Follow the instructions in the motor manufacturer's
manual provided with this agitator to connect the
motor to the VFD. Wire size, fuse size, and other
electrical devices must comply with all local codes

Graco Motor Control

See manual 3A4793 for information on motor control
installation and operation.

Grounding the Agitator

The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
The drum cover and all electrically conductive
objects or devices in the dispensing area must be
properly grounded. Check your local electrical code
for detailed grounding instructions for your area and
type of equipment.
To ground the agitator, connect one end of the
ground wire (G) to the ground connector on the
agitator (33). Connect the other end of the ground
wire to a true earth ground.
