PowerDesigns controllers are experimental systems designed to develop and test electrical systemsincorporating electric motors or actuators. Electrical systems can cause danger to humans, property and nature;therefore precautions shall be taken to avoid any risk. Under no circumstances shall the hardware be used wherehumans or property are put to risk without thoroughly validating and testing the whole system. Software andhardware interact in various ways, and software developers cannot foresee all possible combinations of hardwareused together with their software, nor problems that can occur in these different combinations. Things that can happen, even when using the correct settings, areelectrical failurefireelectric shockhazardous smokeoverheating motors and actuatorsoverstrained power sources, causing fire or explosions (e.g. Lithium Ion Batteries)motors or actuators stopping from spinning/movingmotors or actuators locking in, acting like a brake (full stop)motors or actuators losing control over torque production (uncontrolled acceleration or braking)interferences with other systemsother non-intended or unforeseeable behavior of the system

VESC Tool and the VESC firmware are developer tools that for safety reasons may only be usedby experts and experienced users, knowing exactly what they do.following safety standards applicable in the area of usage.under safe conditions where software or hardware malfunction will not lead to death, injuries or severe propertydamage.keeping in mind that software and hardware failures can happen. Although we design our products to minimizesuch issues, you should always operate with the understanding that a failure can occur at any point of time andwithout warning. As such, you shall take the appropriate precautions to minimize danger in case of failure.
