The arcs from the Tesla coil can set flammable objects on fire. Keep all flammable objects away from the Tesla coil while it is in operation. Always wear eye protection while soldering.
Power semiconductors may overheat and fail violently, causing a shrapnel hazard. Wear safety glasses when working on the board while it is energized. Only power up the board when it is fully enclosed inside the chassis. Keep sensitive electronics away from the Tesla coil at all times. Use the entire length of the included fiber optic cable to distance your computer from the Tesla coil.
Safety Warnings. Electrical Safety Warning The Tesla coil creates extremely high voltage and high frequency sparks. Adult Supervision Required Users under 18 should only use this kit under the supervision of an experienced adult. Pacemaker Warning Persons with electronic medical implants such as pacemakers should not be near the Tesla coil during operation. It is important to prevent arcs from striking ceilings, walls, and floors where wiring may be present. The arcs from a Tesla Coil generate heat, and therefore pose a small fire hazard.
The Tesla Coil may also pose a fire danger if wired improperly, if operated while damaged, if operated for periods exceeding the recommended duty cycle, if ventilation is blocked, or for other reasons. Do not allow arcs to strike fire sprinklers, as they may be triggered. The arcs from the Tesla Coil produce ozone and other gasses, which can build up to toxic levels in unventilated areas.
Do not allow this to occur. There are precisely two places on the Tesla Coil that arcing should occur: Out of the toroid, and in the spark gaps, located below the primary coil. The arcs produced in the spark gaps are much brighter than the arcs emitted by the toroid, and may cause eye damage if directly observed for prolonged periods.
Under some possible failure conditions, parts of the Tesla Coil may maintain a dangerous electrical charge even after the system has been disconnected from power for several minutes. If wiring is ever disconnected during operation there is an especially high risk of equipment maintaining a charge. If there is reason to suspect that danger is present, do not come in contact with any pieces of the equipment, including wiring, for several minutes. If the Tesla Coil is wired improperly, or is damaged, there may be additional risks involved in operation.
There are several extra high-voltage warning labels included with the system. We recommend that these labels be affixed to the Tesla Coil should it be used or stored in a location where persons other than the operator may have access to the unit. We advise that the labels already present on the system not be removed. When not in use for prolonged periods, the Tesla Coil should be partially dismantled to help prevent possible use by unqualified persons.
Detach the black and white low voltage wires from the bolts on the two exposed low-voltage terminals on the power transformer. Note that even when disconnected, these wires pose a dangerous shock hazard if the power is switched on.
The most dangerous components in the Tesla Coil are all part of the relatively low voltage 10,volt circuitry, including the power transformer, the primary coil, and all wiring in the main unit underneath the primary coil.
Arcs can leap several inches from these components. It is imperative to verify that no one can ever come into contact with these components while the main power cord is plugged into an outlet. To help prevent possible damage to the Tesla Coil, verify the following before every operation.
Make sure that the power transformer is placed at least 8 feet 2. Also, make sure that no wires are raised off the ground high enough for arcs to strike them. Verify that all wiring is connected properly. If the wire at the base of the secondary coil is not connected to the grounding terminal, the Tesla Coil may be destroyed when operated.
Make certain that the black power cord coming from the small box at the bottom of the base of the main unit is positioned such that it emerges directly out from the base. If it is coiled back into the base near the chokes, capacitor, or filters, destructive arcing may occur. The Tesla Coil cannot be operated while moisture is present on any part.
The secondary coil is shielded with plastic pipe to prevent damage from contact, but it is not airtight to allow air circulation. Do not run if condensation is present.
The electrical outlet used to power the Tesla Coil must not have a faulty ground. The Tesla Coil will be damaged if the electrical circuit is not grounded properly.
Be sure that there is no conductive material accidentally placed anywhere on the Tesla Coil. If conductive material is placed too close to the secondary coil, destructive arcing may occur. If using a discharge rod, place the rod above the toroid, not below.
