LED Display - Rotating
The front LED display of the ERM-3K4U can
be rotated horizontally and used as a 4U rack-
mounted chassis, or vertically and used as an
upright tower. By default, the
display is in the horizontal
position.
To rotate the display, remove the ERM-3K4U
top cover (above the reservoir), both rack
handles and ears, and both front bezel side
screws.
This enables the removal
of the front bezel and
provides access to the
LED display’s rear acorn
nuts.
The bottom rubber feet
for the ERM-3K4U can be
unscrewed and moved to
the “new” bottom side.
