Suspending Zx5 Speaker Systems - Electro-Voice Zx5-60 Owner's Manual

Suspending Zx5 Speaker Systems

Zx5 enclosures have 5 steel anchor points internally mounted on the top, bottom, and rear. Single
stud fittings can be attached to these anchor plates and used as suspension points. Each of
these anchor plates also has a M8 thread to accept rated forged M8 shoulder eyebolts. 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.

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. Replace any damaged hardware. 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. Replace any loudspeaker systems that are damaged or missing
hardware. Never exceed the limitations or maximum recommended load for the Zx5 systems.
