5.212 Eyebolt Installation

Installation instructions follow:

1.Remove the M10 flat-head bolts from the enclosure (see Figure 18a).

2.Screw the lifting eyebolt with fender washer into the threaded attachment point until the fender washer has contacted the enclosure (see Figure 18b).

3.Continue to finger tighten the eyebolt until the correct alignment position is obtained, a maximum of one complete turn.

4.All hardware supplied by the user must be rated for overhead lifting to suspend the loudspeaker system.

5.Never install the eyebolt without the factory-supplied washer.

Eyebolts must be fully seated and oriented in the plane of pull (see section 5.211 Eyebolt Application Warnings, Figure 17). Always use the factory-supplied fender washer to distribute the load on the enclo- sure. Over tightening the eyebolt with a wrench, screwdriver, etc., can result in a system failure and pos- sible injury.
