Environmental Considerations

The HMI is designed to operate in temperatures from 0° to
50°C (32° to 122°F). It is intended for indoor installations and may not be
suitable for use in certain outdoor applications. Avoid installing the HMI
in environments with severe mechanical vibration or shocks. Do not
install the HMI in enclosures with rapid temperature variations or high
humidity. Either case will cause condensation of water inside the device
and eventual damage to the HMI.
Warning: Do not operate the HMI in areas subject to explosion
due to flammable gases, vapors, or dusts.
Warning: If wiring can potentially be exposed to lightning or
power surges, use appropriate surge suppression devices.

Safety Precautions

Please observe the following precautions and ensure compliance with all
local and national electrical standards when installing the HMI. Failure to
comply with these restrictions could result in loss of life, serious personal
injury, or equipment damage.
Warning: Do not connect the HMI to an AC power source. This
will cause permanent damage to the HMI.
Warning: A Hard-wired EMERGENCY STOP should be fitted in
any system using an HMI to comply with ICS Safety
Recommendations.
Warning: Do not attempt to use a DC power supply that does
not meet the HMI's power requirements. This 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.
