Installing a brandline cover or a top cover
Install a brandline cover or a top cover onto a top frame bracket that is
mounted onto a NEBS 2000 frame bracket. When enclosing a frame with
doors, install the cover on the rear of the frame.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a brandline cover NTPN51 or a top cover that is part of kit
NTRU0185. (If you have a brandline cover with an amber LED lens on
it, use the procedure “Installing an illuminated brandline cover” in the
document P0608794 “Installing an illuminated brandline cover onto a
NEBS 2000 frame”.)
• A brandline cover has words on it and is typically mounted at the front
of the frame at the factory. A top cover is a blank cover and is typically
to be mounted at the rear of the frame after the frame is anchored and
cabled for power. Either cover can be mounted in the front or rear
position. Refer to the figure “Locations of installed brandline covers and
top frame brackets” (page 571).
Procedure steps
1 Hold the brandline or top cover so that:
• the captive screw heads face you
• the words read correctly (brandline only)
2 Fasten each captive screw of the cover to each of the 2 mounting brackets
at the ends of the top frame bracket P0876758 as shown in the figures
