Warning Light Set

Status indicator for high-voltage tests for the dangers of high voltages in accordance with EN 50191.

Warning lights relating to high voltages are described in EN 50191. In this standard (valid only in Europe), it is required that there are warning lights at workstations with voltages above 1,000 V. These red and green lights indicate the status of high-voltage generation in the test field. If the red light is active, then high-voltage can be generated. This however does not necessarily mean that high voltage is present. If the green indicator light is active, this confirms that it is almost certain that no high voltage is either present or being generated. The warnings lights serve exclusively to protect the testing personnel and should not be confused with the test result "Pass" or "Fail".
