3.2.7.2 Recommendation for wiring
a)
If the analogue signal source is single-ended, use a 2-wire shielded cable as follows: 1
st
wire connects the live signal to the drive positive input (+); 2
nd
wire connects the signal
ground to the drive negative input (-).
b) If the analogue signal source is differential and the signal source ground is isolated from
the drive GND, use a 3-wire shielded cable as follows: 1
st
wire connects the signal plus to
the drive positive input (+); 2
nd
wire connects the signal minus to the drive negative input
(-) and 3
rd
wire connects the source ground to the drive GND
