AGENCY APPROVALS
AgENCy APPRoVED MoDEL AREA CLASSIFICATIoN
➀ Dual stage units with ‘HS’ switches are not ATEX approved.
➁ IEC Installation Instructions:
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
For ambient temperatures above +55 °C or for process temperatures above +150 °C, suitable heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
Special conditions for safe use:
When the equipment is installed in process temperatures higher than +85 °C the temperature classification must be reduced
according to the following table as per IEC60079-0.
