Please add three-pole (3-pole) MCCB to distribu-
tion panel for UPS’s input. Do not connect any other
load to it.
Connect the phase cables to
X1 MAINS SUPPLY:
X1/L1 - X1/L2 - X1/L3
terminals, the neutral to
X1
MAINS SUPPLY: X1/N
terminal. Neutral connection
should be done directly from distribution neutral
bus to UPS neutral.
5.3.1.3 . Auxiliary Supply Connection
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 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).
