LEGRAND KEOR T EVO - Auxiliary Supply Connection

26
Connect the phase cables to X1
MAINS SUPPLY: X1/L1 - X1/L2 -
X1/L3 terminals, the neutral to X1
MAINS SUPPLY: X1/N terminal.
Cables must be protected by fuses
or MCCB, refer to Section 5.4
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 in-
stalled upstream.
According to EN 62040-1, the user should place a warning label on the input distribu-
tion 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).
