5.6.6 MOUNTING HEIGHT
The elevation entered into DSAPilot refers to distance from the bottom
of the module’s enclosure or the bottom of the lowest module’s
enclosure in a multi-module cluster to the floor below. Thus, the
mounting height is the same as the elevation in DSAPilot.
5.6.7 WALL BRACKET INSTALLATION
DANGER: ONLY PERSONS WITH THE KNOWLEDGE OF PROPER
HARDWARE AND INSTALLATION TECHNIQUES REQUIRED SHOULD
ATTEMPT TO INSTALL DSA
i
SERIES MODULES OVERHEAD. FAILURE
TO FOLLOW THIS PRECAUTION MAY RESULT IN DAMAGE TO THE
EQUIPMENT, INJURY, OR DEATH.
The supplied Wall Brackets are designed for attachment of the module
enclosure to a wall or other vertical surface. Ensure both the hardware used
to attach to structure and the structure itself are capable of supporting the
load with a design factor that meets applicable building codes.
See Mechanical Drawings in Chapter 9 for weights.
Using the supplied Wall Bracket Mounting Template or exact
measurements, locate the four mounting points required to attach each
supplied Wall Bracket to the supporting structure. Mounting templates
are provided on the shipping-carton and CD-ROM. A bracket template is
shown in chapter 9. Ensure that these mounting points are plumb and
square to each other so the enclosure will be exactly vertical when
installed. Out of plumb and/or square Wall Brackets can prevent proper
engagement with the Enclosure Brackets.
Critical Dimensions:
1. Spacing between the Wall Brackets for a single module must be
within 0.1 in / 3 mm of the dimensions in Figure 5.6.7a. In order to
lift a module onto its wall brackets, spacing between the top wall
bracket and ceiling, or other overhead obstruction, must be 8.5
inches minimum.
NOTE: 8.5 inches allows only 0.25 inches extra clearance.
2. Spacing between the Wall Brackets for modules mounted over-
under fashion must be 4.9 inches.
3. Spacing between the Wall Brackets for modules mounted side by
side must be 5.4 inches.
