Installing an illuminated brandline cover
Install an illuminated brandline cover onto a top frame bracket at the front or
rear of a NEBS 2000 frame to extend the Passport 15000 or 20000 status
indicators when enclosing the frame with doors.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need these tools:
— a step ladder to access the top of the 212.5 cm (7-ft.) NEBS 2000
frame
— a driver to fasten and unfasten very large slotted captive screws as
shown in the figure “Types of screws used with frame enclosure
hardware” (page 120)
— a driver to fasten the very large Pozidriv P0600060 screws as shown
in the figure “Types of screws used with frame enclosure hardware”
(page 120)
— a flashlight to see the connections at the rear of the BIP
• The illuminated brandline cover is intended to be installed at the front of
a NEBS 2000 frame, but you can choose to mount it instead at the rear.
The LED cable accommodates installing an illuminated brandline cover
at the front or the rear, but not both simultaneously.
• For initial installations of a Passport 20000 in a NEBS 2000 frame, the
LED V-cable NTHW66 is already installed and connected at J3.
Procedure steps
1 Use the figure “Paths of the LED cable NTHW66 to the front and rear of a
NEBS 2000 frame” (page 581) to determine whether the NTHW66 is
already installed and connected to J3. The cable is labelled.
If it is installed, go to step 4.
If it is not installed, go to step 2.
2 Route 1 of the 4-pin connectors of the cable NTHW66 from the left rear of
the BIP above J3 to the front of the frame as shown in the side view in the
figures “Paths of the LED cable NTHW66 to the front and rear of a NEBS
