VFD

See the VFD manufacturer's manual for information
on installation and operation of the VFD.
For a Graco supplied VFD, see manual 3A4793 for
information on VFD installation and operation.

Connect VFD to Motor

NOTICE
To avoid equipment damage, do not plug the
motor directly into a wall socket. The motor must
be wired to a VFD.
Follow the instructions in the motor manufacturer's
manual provided with this agitator to connect the
VFD to the motor. Wire size, fuse size, and other
electrical devices must comply with all local codes
and regulations.
Motors are equipped with an automatic thermal
protective device. Review the warning label on the
motor stating the requirement for connecting to the
control circuit terminals of the VFD. UL and NEC
require connection of motor thermostat leads P1 and
P2 into the control portion of a manual reset start
circuit.
For Graco supplied VFDs, motor thermostat leads P1
and P2 connect to terminals 4 and 13B on the VFD,
as shown below.

MOTOR THERMOSTAT LEADS
For ATEX motors, follow the thermal protection wiring
requirements described in the ATEX motor manual.
The ATEX motor manual is included with the agitator.
For Non-Graco supplied VFD — see the motor
Installation manual for instructions to connect to the
VFD.

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.
NOTE: Ground wire is not supplied.
