2000 frame” (page 581) and “Path of the LED cable NTHW66 passing
through the bottom of the top frame bracket” (page 582). Route the cable
so that:
• it fits between the top of the BIP and the bottom of the top of the frame
• at the front of the frame, it routes up through the bottom opening of
the top frame bracket P0876758 as shown in the figure “A top frame
bracket P0876758, underside view” (page 583)
• it temporarily hangs freely down the front of the frame
If a front-mounted illuminated brandline cover is not being installed at this
time, ensure that the connector is protected from causing electrical
shorting (for example, wrap electrical tape over it). Dress the cable aside
until an illuminated brandline cover is installed.
3 Route the other 4-pin connector of NTHW66 across the rear of the BIP to
the right where the LED of a rear-mounted illuminated brandline cover
could be installed. Dress the cable as if an illuminated cover will be
installed.
If a rear-mounted illuminated brandline cover is not being installed at this
time, ensure that the connector is protected from causing electrical
shorting.
4 Fasten a U-shaped bracket P0995495 at each end of the top frame
bracket P0876758 as shown in the figures “An extension mounting
bracket P0995495” (page 584) and “An illuminated brandline cover and
mounting brackets P0995495 without door hardware” (page 585). Use
four Pozidriv 12-mm screws P0600060 each with a lock washer
P0600895 on each bracket.
When upper door hardware is to be installed, combine fastening the door
hardware to the same mounting bracket as shown in the figures:
• “An illuminated brandline cover and mounting brackets P0995495
with a door catch” (page 586)
• “An illuminated brandline cover and mounting brackets P0995495
with a door hinge” (page 587)
5 Connect an end of the cable assembly NTHW66 to the LED board at the
rear of the illuminated brandline cover. The 4-pin connector fits only one
way.
When connecting to a front-mounted brandline cover, route the cable up
through the rectangular opening in the bottom of the top frame bracket, as
shown in the figures “A top frame bracket P0876758, underside view”
