Power Supply Selection
The power supply used to power the HMI should provide an output of
+24 VDC ±20% measured at the HMI power terminal block. A 24VDC
regulated power supply dedicated to the HMI is recommended. Use a
power supply with adequate current rating based upon your particular
model (visit the Support Center Specifications page on our website).
A power line filter installed at the AC input to the HMI power supply is
highly recommended as a safeguard against conducted RF noise, which
is often present on factory power lines. The wires connecting the output
of the power line filter to the power supply should be kept as short as
possible to minimize any additional noise pickup. The case of the power
line filter should be connected to a quiet earth ground. The power line
filter should have a current rating of at least 3 Amps with common mode
and differential mode attenuation. In applications that may have high
