THESE STEPS MUST BE COMPLETED IN THE DEFINED SEQUENCE FOR FCC APPROVALS
For steps requiring connection to the RAMBo refer to the TAZ 6 Wiring connection document
Plug in EL-HR0088 CB Y-Z Harness into RAMBo then pass its 16 position connector through to the interconnect housing transition
Plug in EL-HR0084 CB X Harness into RAMBo then pass its 12 position connector through to the interconnect housing transition
Plug in EL-HR0081 CB Bed Harness into RAMBo then pass its 10 position connector through to the interconnect housing transition- a single red wire without connector will remain unconnected until a later step
Install the Dual Extruder harness (EL-HR0101) from the inside the case, set the orientation of the connector so socket #5 (empty socket) of the connector is away from the USB connector; secure the connector with 3x- 18-8 FHS Black Oxide; tighten to 3in*lbs; Connect the cable to the RAMBo
Position the EL-MS0144 (Sealing Cap) strap so the strap will double over itself when the cap is installed onto the 16position round connector, secure the sealing cap with 1x- 18-8 FHS Black Oxide; tighten to finger tight, the cord should not be able to rotate once tightened. Cover the connector with the sealing cap.
Plug in ELHR0087 CB Extruder Harness into RAMBo then pass its 20 position connector through the interconnect housing transition- Connect the single black wire with connector to the single red wire from EL-HR0081, insert red wire into connector position 1 which is marked MX
Plug in 2x AS-CB0068 CB LCD Harness v2 to the RAMBo and LCD; Connect LCD EXP1 to RAMBo P1; connect LCD EXP2 to RAMBo P2
Plug in Case fan to RAMBo FAN2 location
Plug in EL-HR0082 CB Bed Power Harness to the RAMBo then pass the 2 position connector through to the interconnect housing transition
Route Red and Black Power Supply wires to second tie down, ensure sufficient service loop and bend radius is maintained (see picture), secure wire with Ty Wrap with the securing latch positioned toward the case opening
Install 1x- M3 star washer to the case ground lug near the RAMBo, install 7 ground wires from the internal cable harness to the ground lug, secure with 1x- M3 Nyloc nut tightened to hand tight (if using a ratchet beware of over-tightening the nut)
Install Interconnect Housing on case exterior, verify slot in interconnect Housing aligns with slot in case
Route connectors from each of the internal harnesses into the Interconnect Housing, connectors sizes indicate proper position in the Interconnect Housing
Connect external cables to each of the internal connectors:
Internal Harness (# of connector positions) and mating External harnesses
EL-HR0088 CB Y-Z Harness (16) to EL-HR0091 Y-Z Harness (16)
EL-HR0084 CB X Harness (12) to EL-HR0075 X Harness (12)

EL-HR0082 CB Bed Power Harness (2) to EL-HR0083 Bed Power Harness (10 & 2)
Secure Panduit in Interconnect Housing for 10- 15 mm of Panduit to extend from Interconnect Housing front into the housing; Panduit must be pushed down into the interconnect housing retention slot; wires must be inside the conduit so they are safe from damage when the interconnect cover is installed
Install interconnect housing cover with 6x- M3x12 BHCS and 6x- M3 washer; tighten to hand tight; ensure the cover is flush to the interconnect housing and the interconnect housing is flush to the case. DO NOT TIGHTEN screws past hand tight to force either the cover or the interconnect housing into place.
Inspect wiring layout to ensure all connections are made and wires are laying correctly
Install SD card Bezel into the case cover (entry direction is from the painted side of the cover); install cover onto case with the SD card slot aligned with the SD card reader
Secure the case cover with 14x- M3x8 BHCS and 14x- M3 washers; tighten to 5in*lbs
Install Flexy LCD Knob
Wipe down the bottom of the case with Alcohol; remove three (3) 3/4” square, 1/4” high bumpers from their protective backing apply the bumpers to the case
Install LulzBot test firmware; test unit to ensure all motors (6) correctly rotate, all fans (3) correctly rotate, all switches (7) properly operate, and the LCD display properly lights up, makes sounds as the LCD menu is navigated, and the control Knob functions.
