up slope.
Figure 1. Locating Vibrator on Hoppers
CAUTION
!
Never weld structure with vibrator mounted and wired.
Welding may cause damage to motor windings and bearings.
IMPORTANT
The object of rotary vibration on bins, hoppers, and chutes is
to transmit vibration through the wall into the product
contained inside. If structure is not made rigid, vibrator may
draw high amperage and move material less efficiently.
Make sure structure is free of paint before mounting vibrator.
2. If using customer-supplied mounting plate to mount vibrator onto
structure, do the following:
a. Make sure plate is at least the size of vibrator base.
b. Locate plate so that vibrator can be positioned as shown in Figure 1.
c. Weld mounting plate onto structure.

WARNING
!
Wire vibrator in accordance with National Electrical Code
Article 430. Have wiring installed by a qualified electrician
only.
1. Find wiring diagram number for your vibrator on vibrator nameplate.
CAUTION
!
Before running cord to vibrator, make sure cord voltage
rating equals or exceeds the voltage at which you will be
operating the vibrator. It must have a minimum temperature
rating of 221°F (105°C) and a diameter as shown in Table III.
If wire is not proper diameter, cord grip will not tighten
properly and vibrator could be damaged by moisture or
material getting inside wiring compartment. If cord is
damaged, it could short power supply or short to ground
causing damage to vibrator.
2. Table III provides information on securing the electric vibrator cord grip
when installing power supply and thermistor circuit cords. The frame size
of the electric vibrator will define the size of the cord grip. Each cord grip
is designed for a specific cord diameter range. When installed at the

IMPORTANT
See Figure 5. The compression nut must be tightened to a
position that will provide proper strain relief for the cord. If
the compression nut is not tight enough, the electrical
connections may be stressed. If the compression nut is too
tight, the cord may be damaged. When using a factory cord,
tighten the compression nut to a position that meets the
specified “Distance Between Flats.”
Table III. Cord Grip Specifications
Figure 5. Cord Grip Installation
IMPORTANT
When wiring vibrator, leave slack in electrical cable so that
cable does not become taut during vibration cycle and cause
stress on wire connections. On applications where moisture is
present, leave enough slack in power cable to prevent moisture
from running down cable into vibrator.
3. Wire vibrator according to appropriate wiring diagram inside terminal
box or see Figure 6 or 7. Use closed loop wire connectors only.

IMPORTANT
Read entire section before beginning work.
Checking shaft
rotation
1. Remove cap screws, washers, and vibrator weight covers.
CAUTION
!
DO NOT run vibrator with eccentric weights removed.
Running vibrator with eccentric weights removed will damage
bearings.
WARNING
!
When checking shaft rotation with weight cover removed,
keep hands away from swinging weights. Weights can crush
fingers.
2. Start vibrator for one second, then stop.
3. Observe direction of motor rotation. If motor is not rotating in correct
direction, lockout / tagout / blockout / testout energy source and reverse
rotation. To reverse rotation of three-phase vibrator, reverse any two of
the three power supply wires.
4. Replace weight cover, taking care not to pinch o-ring.
Adjusting
eccentric weights
for 00–10 frame
NOTE
Table IV shows the force output for each weight configuration.
IMPORTANT
For the most efficient operation, vibrator eccentric weights
should be adjusted to the lowest force setting required to move
the material. This will increase vibrator life and reduce energy
costs.
