1.2 General Precautions
Take the following precautions before servicing the Power Supply:
• To prevent the possibility of an electrical shock, always plug the Power Supply into a grounded
power source
• Power supplies produce high voltage. Before working on the Power Supply module, do the
following:
Turn off the Power Supply;
Unplug main power; and
Allow at least 2 minutes for capacitors to discharge
• High voltage is present in the Power Supply Controller. Do not operate with the cover removed
• High line voltages exist in the ultrasonic Power Supply module. Common points are tied to circuit
reference, not chassis ground. Therefore, use only non-grounded, battery-powered multimeters
when testing these modules. Using other types of test equipment can present a shock hazard
• Be sure power is disconnected from the Power Supply before setting a DIP switch
• Keep hands from under the horn. Down force (pressure) and ultrasonic vibrations can cause
injury
• Do not cycle the welding system if either the RF cable or converter is disconnected
• Avoid situations where fingers could be pinched between the horn and the fixture
CAUTION Loud Noise Hazard
Sound level emissions of up to 84.9 dB have been measured using a
standard test load. To prevent the possibility of hearing loss, use
appropriate hearing protection.
WARNING High Voltage Hazard
Be sure the power switch is in the Off position before making any
electrical connections.
NOTICE
Sound level and frequency of the noise emitted during the ultrasonic
assembly process may depend upon a. type of application, b. size,
shape and composition of the material being assembled, c. shape
and material of the holding fixture, d. welder setup parameters and
e. tool design. Some parts vibrate at an audible frequency during the
process. Some or all of these factors may result in sound levels of up
to 84.9 dB. In such cases operators may need to be provided with
personal protective equipment. See 29 CFR (Code of Federal
Regulations) 1910.95 Occupational Noise Exposure. For all other
countries, follow your local regulations.
