3.1.4 MANUAL BY-PASS
Il by-pass manuale, indicated in picture 3.1 as M.B., consists in a breaker which powers the critical load directly
from the main system. This device is particularly useful during ordinary/extraordinary maintenance, as it allows the
operator to deal with the internal circuits with a minimum risk of contact with voltaged elements.
3.1.5 PART LAYOUT
It is important to be familiar with the parts that are necessary during the connection procedures before connecting
the equipment. In order to access the parts which will be described you must remove the “second access”, which is the
metal panel used to protect the inside parts of the U.P.S. and also to protect the user from accidental contacts with live
parts.
