4.6.4 Installation in Hazardous Areas

ACA592–XX transmitters can be installed in a wide variety of industrial sectors. Systems that require ignition
protection are divided into zones. As a result, different instruments are also required.
Note. For additional information, refer to Section 2.5, page 12.
Figs 4.9 to 4.15, page 38 provide details of installations in ATEX/IEC Ex areas.
