According to EN 62040-1, the user should place a warning label on the input
distribution panel and the other primary power isolators, in order to prevent the risk
of voltage backfeed.
This label is supplied with the Installation Manual. It indicates:
RISK OF VOLTAGE BACKFEED
• Isolate Uninterruptable Power Supply before working on this circuit.
• Then check for Hazardous Voltage between all terminals including the protective
earth (PE).
