Power connection diagrams
The following diagram shows the terminal layout for frame size R3, which, in
general, applies to frame sizes R1
terminals.
J1 – DIP switches for analog inputs (two types can be used)
X1 – Analog inputs and outputs
(and 10 V ref. voltage output)
(and 24 V aux. voltage output)
J2 – DIP switch
for RS485 termination
off position
Frame sizes
R5/R6 differ.
