High voltage power supply module not connected occurs due to high voltage power supply module disconnection or output current exceeding specification value applied to maintenance output or abnormal output. The manual's first action is: “When current exceeding the specification value is applied to the maintenance output or abnormal output, the output is shut off to protect the output circuit, and the LEDs for all ION/HV connected to the bar (high voltage power supply module) flash (green) and the error code "E8" or "E9" is flashing in the frequency display.”
