Warning: Do not operate the HMI in areas subject to explosion due to
flammable gases, vapors, or dusts.
Warning: Do not connect the HMI to an AC power source. You will
cause permanent damage to the HMI.
Warning: Do not attempt to use a DC power supply that does not meet
HMI power requirements. You may cause malfunction or permanent
damage to the HMI.
Warning: Do not power the HMI with a DC power supply used for
inductive loads or for input circuitry to the programmable
logic
controller. Severe voltage spikes caused by these devices may damage
the HMI.
Control Panel Design Guidelines
Pay careful attention to the placement of system components and
associated cable routing. These items can significantly enhance the
performance and integrity of your control application.

Control Panel Grounding
The control panel must be connected to a good, high-integrity earth
ground both for safety considerations and shielding purposes. Maple
Systems cannot overemphasize the importance of good grounding. If you
fail to use good grounding procedures during installation, sporadic
malfunction of the HMI may occur:
