Wiring Electric Vibrator Cont.
For wiring diagrams 1A, 1E, 2A and 2C (Fig.4), reinstall the rubber block over the power supply
conductors and install the wiring box cover being careful not to pinch the O-ring. Screw torque
is specified in the Appendix. See figure 8.
For wiring diagrams 5A and 5B, you will note that there is a small 2-pole terminal block in the
wiring box. This is the thermistor circuit. Proceed to Thermistor Wiring.

Terminal Block Hardware Installation
Secure the wire connectors and the shorting bars to the terminal block in the positions shown
on the wiring diagram using the hardware provided. It is essential that the hardware be
positioned as shown in Figure 7.
Note that the closed loop wire connectors provided on the power supply cord are positioned
between the two flat washers. A drop or two of thread sealant such as Locktite is recommended.
Do not use permanent thread sealant because the terminal block will be damaged should you
wish to remove and replace the power supply cord. The terminal block nuts should not be over
tightened since the possibility of damaging the plastic insulating body is high. Reference table
VI in the Appendix for torque values. Make the connections hand-tight followed by a ¼ turn
but never put a ratchet on these nuts.
