Mitsubishi Electric MDT421S: How to Mount and Attach Options to the LCD Monitor

English-14

3. Ventilation Requirements for enclosure 

mounting

To allow heat to disperse, leave space between surrounding 

objects as shown in the diagram below.

4. To avoid monitor from falling

When installing the monitor using the tabletop stands (op-

tional), take measures to prevent the monitor from falling over 

in case of an earthquake or other disaster to lessen the prob-

ability of injury and damage resulting from fall. 

As shown in the 

fi

 gure, secure the monitor to a solid wall or 

pillar using rope (commercially available) strong enough to 

bear the weight of the monitor. (MDT421S: approx. 27 kg (with 

the optional stands))

When you use screw hooks (commercially available), ring 

screw hooks, not C-shaped screw hooks (with opening), are 

recommended. 

Caution:

•  The effectiveness of preventing from falling substantially 

depends on the strength of brackets and base to which 

prevention device from falling is attached. When you 

cannot ensure suf

fi

 cient strength, provide adequate 

 reinforcement. 

•  Though the recommended prevention from falling is 

intended to lessen the probability of injury and damage, it 

doesn’t assure its effectiveness against any kind of 

earthquake or disaster. 

•  Do not sleep where the monitor may topple over or fall in 

case of an earthquake or other disaster. 

•  Before moving the monitor, remove the rope that is 

securing the monitor. Failure to do so may result in injury 

or breakdown of the monitor. 

You can attach mounting accessories to the LCD monitor in

one of the following two ways:

1. In the upright position

2. Lay the screen face down

Lay the protective sheet on a table, which was wrapped 

around the monitor when it was packaged, beneath the 

screen surface so as not to scratch the screen face.

This device cannot be used or installed without the Tabletop 

Stand or other mounting accessory. Failure to follow correct 

mounting procedures could result in damage to the equip-

ment or injury to the user or installer. Product warranty does 

not cover damage caused by improper installation.

Failure to follow these recommendations could result in void-

ing your warranty.

Use M6 screws (having a length 10 mm longer than the thick-

ness of the mounting bracket) and tighten them securely. 

Prevent the screws from loosening using spring washers, 

etc. MITSUBISHI ELECTRIC recommends using mounting 

interface that comply with TÜV-GS and/or UL1678 standard 

in North America.

Caution:

For preventing the monitor from falling.

•  Install the monitor with metal brackets for wall or ceiling 

installation (commercially available) on your own respon-

sibility. For detailed procedures of installation, refer to the 

instructions of the metal brackets. 

•  To lessen the probability of injury and damage resulting 

from fall of the monitor in case of earthquake or other 

disaster, be sure to consult the bracket manufacturer for 

installation location. 

•  To lessen the risk of falling of the monitor, thread commer-

cially available rope through the handles at the right and 

left of the monitor and secure the rope to the wall mount 

brackets or ceiling mount brackets. 

•  Do not sleep where the monitor may topple over or fall in 

case of an earthquake or other disaster.
