5.2.4    External maintenance by-pass. 

In  some  cases,  in  order  to  facilitate  maintenance  operations  of  the  individual  units  making  up  the  system, it may be 
advisable to install an external maintenance by-pass. 
The new disconnector located on the by-pass line (Q2) must be provided with auxiliary contacts (one for each CPS). 
The  position  of  the  contact    is  opposite  to  the  position  of  the  switch,  thus    the  contact  must  be  closed  when  the 
disconnector is open. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The contacts of each disconnector must be connected to the corresponding CPS terminals, as shown in the diagram.
