[. . . ] 14 ELECTRO-VOICE® Zx5 Owner's Manual 2 Safety First When setting up, installing and using the Electro-Voice® Zx5 speaker system, there are a number of precautions that you should follow: · When Electro-Voice® Zx5 speakers are used for portable applications in which they will be positioned directly on the floor, make sure that the floor or stage is solid and secure. · Electro-Voice® Zx5 speakers include 1-3/8 inch stand mounts to allow mounting on tripod stands. Make sure to: · Check the specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker. · Check that the speaker stand is placed on a flat, stable surface and be sure to fully extend the legs of the stand. Do not try to make the stand "taller" and compromise its structural integrity. · Route cables and position the stand so that performers, production crew and audience members will not trip over the stand or cables and pull the speaker system over. Secure cables with wire ties or tape whenever possible. · Do not attempt to suspend more than one speaker on a stand designed for a single speaker · Unless you are confident that you can safely handle lifting the weight of the speaker onto the stand, ask another person to help you place it. · If you intend to hang or fly the Zx5 system, only do so safely with the correct hardware and accessories. WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. In addition to these points there are five additional M8 threaded points; two on the handle side, and three on the rear. These points can be used for suspending Zx5s vertically, horizontally, individually, in clusters, or to attach to EV mounting brackets. Working load limits for the Zx5 and fittings are shown in Figure 2. Zx5 has been pull tested and exceeds a safety factor of 8 to 1 when properly used. Figure 2: Working Load-Limit Rating of Zx5 Speaker System Prior to each use, inspect the grid assembly or suspension point(s) and associated hardware for any cracks, deformations, broken welds, corrosion, missing or damaged components which could reduce the grid assembly or suspension point(s) strength. Never exceed the limitations or maximum recommended load intended for grid assembly design or suspension point(s). As an added safety measure, it is suggested that the user install a second suspension point back to the grid (or building structural supports). This redundant safety point should have as little slack as possible (less than one inch is preferable). Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components, which could reduce enclosure strength. Inspect the bracket assembly on the enclosures for any cracks, deformations, missing or loose screws which could reduce the flying hardware strength. [. . . ] Inspect the bracket assembly on the enclosures for any cracks, deformations, missing or loose screws which could reduce the flying hardware strength. Replace any loudspeaker systems that are damaged or missing hardware. Never exceed the limitations or maximum recommended load for the Zx5 systems. 5 ELECTRO-VOICE® Zx5 Owner's Manual Suspending Zx5 Speaker Systems (cont') Zx5 M8 Suspension Points Metric (M8) inserts are equipped on the top and bottom of the enclosure, around the handle, and on the back of the enclosure for a total of 10 points.
