Toa HY-1500HW - Manual (Page 4)

When installing the safety wire, be sure to follow the instructions below.
Failure to do so may cause the speaker to fall off, resulting in personal
injury.
• Use a wire rope of 2 mm (0.08") or more in diameter. (The safety wire is not supplied.)
• Tighten the safety wire to take up the slack. Otherwise, impact shock at speaker fall may cause the wire-
connected parts or wire itself to break.
• Install the safety wire to a place that can structurally support the full weight of load.
• Screw a speaker suspension bolt (M8) into one of the screw holes on the speaker's bottom surface.
Then, connect the safety wire to the bolt.
4. INSTALLING TO A CEILING
The brackets to be used are as follows.
For vertical speaker installation:
V-Series Mounting Brackets (HY-1200VB, HY-1200VW, HY-1500VB and
HY-1500VW)
For horizontal speaker installation: H-Series Mounting Brackets (HY-1200HB, HY-1200HW, HY-1500HB and
HY-1500HW)
The example here shows the installation procedure of the mounting bracket using the HS-1200 series speaker
system.
4.1. Using the H- or V-Series Mounting Bracket Only
Step 1. Attach the supplied bracket holder to the speaker.
Fix the bracket holder using the supplied 2 screws (M6 x 20)
after aligning its datum line with the positioning mark (
) on
the speaker system.
Follow the same installation procedure to the other side.
