Safety Precautions
•Turn off power to the buzzer before installation, removal, wiring,
maintenance, and inspection. Failure to turn off may cause electrical shocks or fire hazard.
•For wiring, use wires of a proper size to meet the voltage and
current requirements. Tighten the M3 screw terminal of the cyclical
sound adapter to a torque of 0.6 to 1.0 N·m. Improper soldering or
failure to tighten the terminal screw may cause overheating and
fire.
Instructions
Notes on Panel Mounting
Use an optional locking ring wrench to mount the unit onto a
panel. Tightening torque should not exceed 0.88 N·m. Do not use
pliers. Do not tighten with excessive force, otherwise the locking
ring will be damaged.

Notes on Installing the Cyclical Sound Adapter
1.The cyclical sound adapter can be used on 12V and 24V DC
buzzer units (UZ6-11, UZ6-12).
2.Mount the buzzer unit on the panel before installing the cyclical
sound adapter on the panel. The buzzer unit cannot be mounted
with the cyclical sound adapter installed.
3.When installing the cyclical sound adapter, make sure that the
TOP marking on the cyclical sound adapter is on the same side
as the TOP marking on the buzzer unit and press in.
Note: When wiring, do not apply
exessive force to X1 and X2
terminals.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. SnAgCu type lead-free solder is recommended.
When soldering, do not touch the buzzer unit housing with the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
