BACKFEED PROTECTION DEVICE
The back-feed protection device, as indicated by the EN 62040-1 Standard, is optional and
can be installed during the UPS production phase; the installation on site can only be carried
out by skilled personnel.
The device is a contactor that automatically disconnects the bypass line in case of failure of
the static switch, in order to avoid voltage feed-back on the input terminals during the a mains
failure.
The use of a device installed inside the UPS allows a higher flexibility of use, as only the
bypass line is cut leaving the rectifier battery charger in operation.
The use of an external device forces the user to separate the UPS supply lines (rectifier and
bypass) if the flexibility and availability of the UPS are supposed to be kept unaltered.
The following table shows the main electrical characteristics of the external sectioning device
in case this solution is chosen.
