If you are not sure, ask your instructor to check your circuit. When working with voltage sources above 600V but less than 8000V, you should stay at least three feet away from any energized item. Keep in mind that overstressed or overheated components may explode, that short circuits or faults may cause violent arcing, hot gas, and that tiny drops of melted metal can be ejected with high velocity straight into your face. If you work with motors, make sure they are coupled properly and firmly tightened to the main frame. The couplings should always be shielded.
Centrifugal force can transform couplings into dangerous projectiles.
Be aware of possible stroboscopic effects that make rapidly moving parts seem almost stationary. All connections must be done correctly. A loose connection may open suddenly and consequently a dangerous situation will develop. Many terminals and components are not electrically insulated. Do not disconnect or remove instruments or parts from the benches.
