LEGEND:

1) Re-settable input protection

2) Input EMI filter + back-feed protection:

Input filter for protecting the UPS and load against any electromagnetic disturbances.

Back-feed protection: intervenes when the mains power supply fails, therefore isolating the UPS from the

input socket to prevent any back feed to the mains power supply. This protection is required to prevent any

voltage from returning to the supply, which could put the operator at risk whilst carrying out maintenance

work.

3) Rectifier/booster block protection fuse:

This fuse is dependent on the status of the re-settable input fuse (1): a fault occurring to the rectifier/booster

will open this protection before the input fuse intervenes, ensuring that the power supply to the connected

load is not interrupted, as the by-pass line will remain powered.
