Overview of wiring installation (R1...R4)
The figure below shows an overview of the terminal layout for
frame sizes R1...R4.
J1 – DIP switches for analog inputs (two switch types can be used)
J1 J1
AI1: (in voltage position) 0(2)...10 V
AI2: (in current position) 0(4)...20 mA
X1 – Analog inputs and outputs
(and 10 V ref. voltage output)
X1 – Digital inputs
(and 24 V aux. voltage output)
X1 – Relay outputs
J2/J5 – DIP switches
for RS485 termination

The figure shows the R3 frame size.
Other frame sizes have similar layouts.
WARNING! For IT systems, corner grounded TN systems and
residual current circuit breakers, remove screws at EM1 and
EM3 to disconnect the EMC filter. Note that when the EMC filter
is disconnected, the drive is not EMC compatible.
