Electric Vibrators
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.
