When wiring the electric vibrator leave enough slack in the cord so that the cord does not become taut during operation causing stress on the connections It is always best to position the cord down so that should there be any moisture present the moisture would tend to run down instead of into the vibrator wiring box Trim the cord by removing the jacket exposing the conductors and ground wire for approx 6 in Be careful not to cut the conductor or ground wire insulation Insert the cord through the conduit fittings and then through the opening in the side wall of the wiring compartment Position the jacket of the cord approx in beyond the inside wall of the wiring box wall Assemble all conduit fittings making sure that there is always minimum thread engagement of 5 full threads Install the conduit seal following all instructions being certain to comply with Articles 501 and 502 of the NEC LIN MU MVTX Manual 12 2 11 g d MTVX Manual 12 2 11 12 2 11 2 52 Page 9 MU Wiring Electric Vibrator Cont Trim the conductors within the wiring box leaving plenty of slack Next strip the conductor insulation for 1 4 in to 3 8 Crimp on closed loop wire connectors Use only the intended crimping tool as designated by the wire connector manufacturer The conductors should be neatly arranged on the floor of the wiring box The wires should not cross over each other See Figure 4 Figure 4 Proper Wiring Arr
