2.WIRING THE LV-1101/1102 W/OPTION ‘D’ WITH STRAIN RELIEF CABLE FITTING.

a.Remove the gland nut and tapered rubber grommet from the strain relief cable fitting and slide them over the cable with the gland nut going on first.

NOTE

Check the match of the outside diameter of the cable with the inside diameter of the grommet. No more than .020" of play should be evident.

b. Strip the outer jacket of the cable back 2 inches. Strip the insulation from the individual conductors approximately 1/4".

c.Each microswitch is supplied with 3 flag slip-on terminals. Remove from the microswitch and crimp or solder to the appropriate leads.

d.Feed the cable up through the cable fitting and attach the leads to the microswitches per Figure 1 or Figure 2 Wiring Schematics, below.

e.Push the rubber grommet into the conical hole in the cable fitting. Slide the cable thru until the end of the jacket is flush with the inboard end of the cable fitting. Grip the cable to prevent rotation and thread the gland nut onto the cable fitting to seal the grommet tightly to the cable.

3.If using a fitting other than the strain relief cable fitting, attach the fitting to the body and attach the conduit to the fitting and wire to local code per Figure 1 or Figure 2 Wiring Schematics.

Microswitch actuation point may be monitored by an audible click or with an OHM meter before connecting line power to the terminal strip or by monitoring the voltage supplied to the load through the microswitch.
