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 DSAi 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.
