1.2.  General presentation 

1.2.1.  Of the product 

This manual describes the instructions for installation, use, setup and maintenance of the dual plate D700.  
 
This plate is for the regulation of generators with field current of up to 25 A in continuous operation, and 50 A 
maximum in short-circuit conditions for 10 seconds maximum.

This plate has been designed to be installed in a control and power switching cabinet. These cabinets must 
provide  the  minimum  conditions  for  protection  and  safety  of  electrical  installations  up  to  300  VAC 
phase/neutral, in force in the place where the plate is installed.  
 
It  consists  of  a  frame  equipped  with  two  AVRs,  a  set  of  24  VDC  power  supplies,  and  a  set  of  relays  and 
terminals. To make it easy to remove and replace a faulty AVR, even when the generator is still running, a 
set of disconnect terminals has been installed on the measuring and power supply circuits of each AVR. 
 

Note:  For  more  information  on  AVR  operation,  please  refer  to  the  installation  and  maintenance 
manual for D700 AVRs (LEROY SOMER reference: 5513en).
