If auxiliary supply exists, remove all bridges.
When used, the residual current earth leakage
protection system must be common for the two AC inputs and installed upstream.
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 sent 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).
