Leroy-Somer R630, Installation And Maintenance Manual, Page: 12 / 46

1 - FUNCTIONAL
- This unit is mainly an interface between external signals
and low power electronics.
- It is composed by :
• The adaptation three phases transformer between input
voltage and measurement circuits.
• The burden resistor of parallel CT.
• The adaptation transformer between input voltage and
low power electronic supplies.
• The interface input relays between command / control
terminals and internal circuits.
• The interface between 64pts BUS and the analogic in-
put / output terminals
2 - ADJUSTMENTS
- Setting of the auxiliary input voltage (terminals 16,17) :
(110 or 220Vac) by jumpers.
