Conditions of Safe Use

5 Conditions of Safe Use
Conditions of Safe Use - General
• The devices shall be mounted in an IECEx / ATEX certified enclosure with a minimum
ingress protection rating of at least IP54 and used in an area of not more than pollution
degree 2 as defined in IEC 60664-1.
• The enclosure must utilize a tool removable cover or door.
• Provision shall be made external to the equipment to provide transient protection at a level
not exceeding 119 V at the power supply terminals.
• The standard 5-wire resistive touch screen ("TA" option) has not been evaluated for poten-
tial damage from UV exposure. Therefore, installation is restricted against direct exposure
to sunlight.
• Examples of acceptable installations include indoor applications away from direct sun-
light; outdoor applications with shading to prevent direct sunlight; etc. Regular inspections
are necessary to check for deterioration of the touch screen. Return the VisuNet appara-
tus to factory for repair or replace the VisuNet apparatus if damage is detected.
Conditions of Safe Use - D1
• The intrinsic safety barrier, gaskets and touch screens are suitable for a service tempera-
ture range of -20°C to 50°C.
• When mounted in a method that reduces the environment of the back side of the compo-
nent to EPL Gc or nonhazardous, the exposed display/touch-screen is suitable for EPL
Gb and/or Db.
• The input terminals are suitable for field wiring. See manual for installation details.
• The standard 5-wire resistive touch screen (TI option) has not been evaluated for potential
damage from UV exposure. Therefore, installation is restricted against direct exposure to
sunlight is required. Regular inspections are necessary to check for deterioration of the
touch screen.
• Brightness Control Buttons - located on the back of the unit, were not evaluated as 'ic' cir-
cuits.
• The component is equipped with a separate ground terminal for the intrinsic safety barrier.
Proper handling of this ground connection is required.
• The standard resistive touch screen (TI option) does not pose a static hazard from normal
use when the component is properly installed. Keep away from high charge processes.
• The hardened resistive touch screen (HI option) has an outer layer of glass and no special
consideration for static is required.
• When used within the service temperature range, the touch screen is suitable for a T6
temperature classification.
