Radio Frequency System Safety Considerations
5.1.
Introduction
Vante manufactures a variety of instruments that use radio frequency (RF) for sealing, welding,
and forming thermoplastics. Typical uses include the sealing of PVC and EVA tubing, and
plastic welding or forming in manufacturing processes. When in operation, these RF instruments
emit radio frequency energy to people, other instruments, and equipment located in close
proximity. Vante RF instruments operate at a frequency authorized by the Federal
Communications Commission (FCC) and the International Telecommunications Union (ITU) for
industrial, scientific, and medical (ISM) use. The following is an advisory regarding RF
instrument use and associated safety considerations.
5.2.
RF Effects on Human Tissue
Misuse or direct contact between tissue and RF contacts can result in RF burns.
5.3.
RF Effects on Pacemakers
There is no evidence that Vante RF instruments interfere with the function of modern cardiac
pacemakers.
5.4.
Electrical Safety
Vante RF devices meet or exceed appropriate electrical safety standards, and pose no electrical
shock hazard when used with properly fused and grounded outlets.
5.5.
RF Effects on Electronic Equipment
Vante instruments produce RF power, and during operation they emit some RF energy. While
most modern electronic equipment and instruments provide shielding from RF energy,
improperly shielded electronic devices operating in close proximity to an RF instrument may be
affected. If interference is suspected, appropriate electronic shielding, moving equipment further
away from the RF instrument, or operating the devices on different electrical circuits may be
necessary.
5.6.
RF Effects in Potentially Explosive Atmospheres
Do not operate Vante RF instruments in any area with a potentially explosive atmosphere. It is
possible for the RF electrodes to arc, initiating an explosion or fire.
Appendix: Controller Interface
The RF generator is controlled by a peripheral device, usually a handheld sealing head.
NOTE:
The J1 and J2 ports on the generator are not used.
