Environmental Considerations
The 6156 Industrial Monitor requires a minimum free air space of
76.2 mm (3 in.) behind and 50.8 mm (2 in.) above and below for
proper cooling. Allen-Bradley Industrial Monitors have been
designed to function without cooling fans. Therefore, maintenance of
fan filters and access to them need not be a concern.
Strong magnetic fields near the front of the monitor outside the
enclosure could potentially distort the image over time. This type of
image distortion generally disappears after degaussing occurs.
Allen-Bradley Industrial Monitors automatically degauss each time
AC power is applied, or when the degauss button is pressed.
Note: The internal degauss will not prevent color impurities caused
by local magnetic fields. Make certain the Industrial Monitor’s
enclosure is free of residual magnetism.
Panel Mounting
The panel on which you will mount the Industrial Monitor should be
at least 14 gauge to insure a NEMA 4 seal and proper support for the
unit. The mounting studs attached to the rear of the monitor bezel
will accommodate this minimum thickness panel and panels up to
6.35 mm (0.25 in.) thick.
To install the Bulletin 6156 Industrial Monitor:
1. Confirm that the shipping carton contains a package of 20 10-32
lock nuts and 20 flat washers. You will need 14 nuts and washers
for installation.
2. Refer to the physical dimension drawings (Figures 1 and 2, pages
4 and 5) and confirm that there is adequate space behind the
panel where the unit is to be situated. Remember to allow extra
space for air circulation.
3. Refer to the panel cutout drawing (Figure 3 Page 8) for
dimensions of the panel cutout and mounting hole locations. Cut
and drill the panel.
4. Carefully remove the monitor from its packaging. Avoid
damaging the monitor gasket.
Tip: It will be easier to install the monitor if you support it with a
shelf or other support adjusted to the appropriate height.
