Internal DC bus capacitors hold lethal voltages long after all external breakers are turned off. Wait a minimum of 10 minutes for the internal bleed resistors to drain the charge before touching internal busbars. An internal static bypass switch acts as a

An internal static bypass switch acts as a high-speed safety net. If the UPS experiences an internal fault or an extreme overload condition, the static switch automatically transfers the load to the utility source in less than 4 milliseconds, preventing any interruption to the connected equipment. 3.
