This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
This certificate covers Model Series KM8215, KM8219, KM8222, RM8215, RM8219, RM8222, PC8215, PC8219 and PC8222. These devices are computers and monitors with 15", 19" amd 22" displays, that are intended for installation into a panel or suitable enclosure. The only accessible portion of the computer to the end-user is the Display, which can be a touch screen. The operating ambient temperature range is 20°C to 50°C.
See Annex for additional information.
The devices shall be mounted in an IECEx certified enclosure with a minimum ingress protection rating of at least IP54.
The enclosure must utilize a tool removable cover or door.
Provision shall be made to provide transient protection device to be set at a level not exceeding 119 V at the power supply terminals of the apparatus.
The standard 5-wire resistive touch-screen (“T” option) has not been evaluated for potential damage from UV exposure. Therefore, installation is restricted against direct exposure to sunlight is required. Examples of acceptable installations include indoor applications away from direct sunlight; outdoor applications with shading to prevent direct sunlight; etc… Regular inspections are necessary to check for deterioration of the touch-screen. Return the VISUNET apparatus to factory for repair or replace the VISUNET apparatus if damage is detected.
