                           the emergency line fitted with a GenSet system.






                           Line-line
                           If the main network goes down, the ATS021 and ATS022 devices allow switching to a second line
                           used as a reserve line. ATS022 allows you to select which of the two lines available is to be the

          CB1          CB2  serve line, disconnecting the non-priority loads (NPL) shunted from the main busbar.
