X or Y-Post - Modular or Hardwired Termination Hub (on pages 9 & 18) Wiring Schematics: 34 INCHES LONG 40 INCHES LONG EACH 9 FEET LONG System 4-Circuits: 3 with One Shared Neutral; One with its own Neutral; System Ground and Isolated Ground (3+1) 4-Circuits: 2 with One Shared Neutral; Another 2 with One Shared Neutral; System Ground and Isolated Ground (2+2) 3 Circuits: Each with own Neutral; System Ground and Isolated Ground (3SepN) WARNING: All electrical installations should be performed by a qualified person in accordance with codes and regulations applicable at the installation site. Circuits should be checked for proper voltages all sources of power supply must be disconnected prior to any servicing. NOTE: These three wiring schematics each have an individual, physical "key" so that they can't be interconnected inadvertantly (e.g. a harness will not plug into a harness). Notes on Chicago Installations: Must be hard wired under authority of a permit by a contractor licensed in the city of Chicago. Harnesses and quick connect connectors not allowed in the city of Chicago. UL listed under file # E Page 1 of 20

2 Fig. 1c Optional Method for Installing on a 95" Post Assembly to "X" Post If installing on a short post, the hub mount piece must be installed first. Note: This figure shows screw and T-nut installation from the back side of the base enclosure. Note: Fish T-nut into slot using a piece of tape. NOTE: The hub mount and extension are the only extrusions that are black annodized. TAPE 1a. Mount extension piece flush with the top of hub mount. TOP OF BASE ENCLOSURE 1b. Tighten four (4) set screws. 1c. Loosely attach four (4) 1/4-20 T-nuts and four (4) 1/4-20 x 3/4" socket head cap screws (torque to 50 in-lbs. or 4-5/32 ft.- lbs.) to four (4) holes in hub base enclosure (Fig. 1c). 1a 1/4-20 x 3/4" Socket Head Cap Screw T-NUT AND SCREW LOOSELY FITTED 3-1/2" HUB MOUNT 1b 1c 7" EXTENSION PIECE Page 2 of 20

4 3a 3. Vertical Tube Assembly Starting from inside of the tube back, thread cable ties through two (2) zip tie holes back to inside of tube back. This is very important for assembly on "X" post. It is very difficult to thread cable ties after tube back is assembled on the "X" post. CABLE TIES 4. Align top tube back mounting hole with top bracket clearance slot and formed hole (4a). Screw #10-32 thread forming screw through tube back mounting hole, tube bracket right clearance hole and into tube bracket left formed hole (4b). Tighten screw. 3b ASSEMBLED TUBE BRACKET #10-32 SCREW BACK OF VERTICAL TUBE BACK 4b VERTICAL TUBE (BACK) 4a 3c Page 4 of 20

5 6. Moving down tube back, fasten tube back to tube brackets as described. Tube brackets may be moved along post to align tube bracket mounting holes with corresponding tube back mounting holes. Repeat for all remaining tube back mounting holes. 5. Route cables along tube back and make appropriate power and data connections. Zip tie cable(s) to tube back. Align one end of tube front with the tube back. Align snap features on tube front and tube back. Push/squeeze tube front onto tube back until snap features are fully engaged for full length of tube. 6 TUBE FRONT HARNESS TO HARNESS CONNECTOR POWER FEED Page 5 of 20

6 7. Place Hub Power Piece on Base Enclosure. Don't fasten to the hub at this time. 8. Power piece is open at its back so that it slips around the cables and vertical tube. NOTE: You'll need to lift the conduit out of the way before setting the hub power piece in place. Then feed conduit through opening. Power piece is open at its back so that it slips around the cables and vertical tube. 7 HUB POWER PIECE Page 6 of 20
