OURCE
The status display touchscreen is equipped with a 24VDC input. Supplying
power other than 24VDC +/- 15% will severely damage the status display
touchscreen. Thus, check the power supply supporting the DC power
regularly.
3.3. G
ROUNDING
Without grounding, the status display touchscreen may be severely affected
by excess noise. Make sure that the grounding is done properly from the
power connector at the rear side of the status display touchscreen. When
power is connected, make sure that the wire is grounded.
Use a cable of at least 2mm
2
(AWG 14) to ground the status display
touchscreen. Ground resistance must be less that 100
Ω
(class 3). Note that
the ground cable must not be connected to the same ground point as the power
circuit.
3.4. I
NSTALLATION
Communication cables must be separated from power cables for operational
circuits. Only use shielded cables to avoid unpredictable problems.
