Appendix 8 Backfeed Protection

Backfeed Protection

The presence of a backfeed protection is required by IEC 62040-1 UPS standard.
An additional external isolation device must be installed upstream the UPS system. A magnetic
contactor or a circuit breaker with UVR (Under Voltage Release) functionality can be used for this
purpose.
The isolation device must be able to carry the UPS input current (common input in case of single
source, bypass input in case of dual source).
E.g. an isolation device can be a magnetic contactor. The coil of the contactor should be supplied by
(eg. fused L1-N voltage) the input source in single mains configurations or by the bypass source in
dual mains configurations, via the output port as per Appendix 6.
If the contactor coil exceeds the voltage/current limits of the UPS output port a 24 Vcc source should
be generated from the same source the contactor coil is supplied from, in order to supply an
additional external auxiliary relay coil. The relay contact, properly rated, should allow to supply the
contactor coil.

Connections to provide backfeed protection are show into following schematic diagram.
