STEPS
1. Mount Safety Disconnect Switch.
2. Remove enclosure cover by loosening two cover screws and lifting cover off hinges.
3. Remove switch (see REMOVE SWITCH section). This is recommended to prevent steel debris from entering switch components.
4. Drill conduit hole in desired location. Fitting size as follows: 1.109" (28.2 mm) diameter hole for 3/4" (19.05 mm) hub.
5. Install conduit fitting. Ensure "O" ring is properly seated and the inside locking ring is seated tightly against the inside surface of enclosure to ensure proper grounding.
6. Re-install switch (see REPLACE SWITCH section).
7. Connect wires (see WIRING section).
8. Replace cover and hand thread screws to engagement. NOTE: Handle must be in the "OFF" position to close cover. NOTE: Verify that O-rings are properly seated under screws. Tighten screws to 15-18 in.-lbs. (1.7-2.0 N-m) torque.
REMOVE SWITCH (Fig. 2)
NOTE: DO NOT REMOVE DIN RAIL.
1. To remove switch loosen middle mounting screw on ground bus terminal block (A) using a flathead screwdriver, and slide to the side with neutral bus (B).
2. Remove both mounting screws securing the switch using a #0 Phillips screwdriver.
3. Insert a flathead screwdriver in switch tab (C). Gently pull tab outward while pulling switch up; beginning with tab side and then opposite side.
NOTE: If replacing the switch component remove switch rod by loosening set screw (D), pulling rod out of switch and set rod aside.
NOTE: If replacing the switch component you can remove auxiliary contact on switch by inserting flathead screwdriver tip between switch and auxiliary contact and pressing outward.
REPLACE SWITCH
NOTE: If replacing the switch component re-install switch rod ensuring it is fully seated in bottom of pocket. Tighten set screw to 7-9 in.-lbs. (0.8-1.0 N-m).
NOTE: If replacing the switch component attach auxiliary contact (if applicable) to switch by fitting the tabs on top and pressing in auxiliary contact in a downward motion.
1. Mount switch onto DIN rail by hooking back side hinge onto DIN rail, then gently pull switch tab outward and push switch down until it snaps into place.
2. Slide switch into position and align the two screw holes with threaded holes in base plate. Tighten 2 mounting screws to 4 in.-lbs. (0.4 N-m).
3. Slide ground and neutral bus terminal blocks back to position next to switch and tighten ground bus mounting screw to 7-9 in.-lbs. (0.8-1.0 N-m). Ensure terminal blocks are not loose on DIN rail.
4. Verify switch cover properly mates with switch mechanism with cover closed and ON/OFF handle moves freely.
