How to Operate
5-1. Preparation for start-up
Before supplying power, read and understand the following precautions. Ignoring these precautions may
cause an electric shock or damage the buzzer unit.
• Connect the buzzer unit to a grounding circuit.
• Check that the wiring is connected to external device properly.
• Check that the power supply voltage is compliant with the specifications.
• Because the external contact may be activated during the adjustment, take measures to prevent an
activated contact from having influences on external circuits.
• Make sure to use a fuse with the specified ratings to prevent fire.
