3.6 Physical Installation
3.6.1 ORIENTATION
1. When installing the enclosure, there is a correct “top”
and “bottom”. This cannot be assumed from the
physical appearance. Instead, orientation depends on
application and desired acoustical performance
determined using DSAPilot.
2. Ensure the enclosure is oriented correctly by
verifying which ends are supposed to be the top and
bottom for the intended application. The Signal End
is the end with the identification LED, visible on
one end of the front of the enclosure. The Power
End has the ac mains connector.
NOTE: The desired coverage cannot be achieved if the
enclosure is incorrectly oriented.
3.6.2 MOUNTING
WARNING: Comply with all installation warnings in Section 5.6.1.
The DSAi Series modules are normally intended to be flush-mounted
against a vertical surface capable of supporting their weight.
1. Using the template printed on the shipping box, locate and position
the supplied Wall Brackets to structure.
2. Attach the Wall Brackets to structure. You must provide attachment
hardware and ensure the attachment method and structure are capable
of supporting the intended load. Position the Wall Bracket weld nuts
left or right to allow clearance for later insertion of the Retainer Bolt.
3. Ensuring they are oriented properly, install the two Enclosure
Brackets on the module. Insert and hand-tighten the supplied 3/8-16
Enclosure Bracket Bolt and Lock Washer for each Enclosure
Bracket.
4. Lift the enclosure onto the installed Wall Brackets.
WARNING: Use at least two people for lifting enclosure onto the
brackets.
5. Insert and snugly tighten at least one of the supplied 1/4-20 Retainer
Bolt and Lock Washer through the side of either of the Wall and
Enclosure Brackets. This prevents the enclosure from being lifted off
the Wall Brackets.
6. Securely tighten each 3/8-16 Enclosure Bracket Bolt to lock the
enclosure at the desired horizontal angle.
