11.4.2 Installing an EXD3902 on a Wall
This section describes the procedure and precautions for installing an EXD3902 on a wall.
Context
Place a foam pad or cardboard under an EXD3902 to protect the EXD3902 housing from
damage during the installation.
The wall for installing EXD3902s must meet the following requirements:
The wall must be able to bear a weight four times heavier than the EXD3902's weight.
Expansion bolts must be tightened to 30 N·m to ensure that the bolt assemblies work
properly and the wall remains intact.
Procedure
Step 1
Determine a position for installing the EXD3902 on a wall, use a level to verify that the
marking-off template is placed horizontally, and then use a marker to mark anchor points, as
shown in Figure 11-12.
