BREAKERS
The U.P.S. has a system of breakers, which allows the user to carry out the necessary
operations in order to use and carry out maintenance on the equipment and to shut down the
power supply if there is an emergency. A sticker placed on the second access specifies the
name of each switch near the switch itself. The by-pass switch contains a protection device so,
as it cannot be disconnected inadvertently. The user can remove this protection device if
he/she decides to carry out a manual by-pass (Chapter 5).

3.3.2
FUSES
The U.P.S. includes a system with two fuse groups, both counting three fuses each which
are able to disconnect electrical power input (points 1 and 7 picture 6), when the electrical
power is not within the set parameters. The type of fuse, which is used, guarantee quick
intervention and therefore are a guarantee also for optimum protection of the internal devices.
Furthermore, there is also a fuse on the line, which connects the U.P.S. to the batteries (point
6 picture 6), both for internal and external batteries.
Picture 12
Board A, (picture 12), to the user’s left, protects the state of the rectifier input, board B
(picture 12), to the user’s right, protects the reserve line. Whereas the single-fuse board C
protects the battery line.
