•
Are intended for use in areas in which explosive atmospheres caused
by gases, vapors, mists, or air are likely to occur occasionally. Such
locations correspond to Zone 1 or 2 classification according to ATEX
directive 2014/34/EU.
IEC Hazardous Location Approval
The following applies to products with the IECEx certification:

for short periods. Such locations correspond to Zone 1 or 2
classification to IEC 60079-0.
•
The type of protection is “[Zone 0] Ex ib[ia] IIC T4” according to
IEC 60079-11 and “[Ex iaD]” according to IEC 60079-11.
•
Comply to Standards IEC 60079-0:2004, IEC 60079-11:2006,
IEC 60079-26:2004, IEC 61241-0:2004, and IEC 61241-11:2005,
reference IECEx certificate number IECEx BVS 09.0023X.
Special Conditions for Safe Use:
The intrinsically safe circuits (ch0 to ch7) may extend into areas with
combustible dust. However it shall be ensured that the apparatus, connected
to these intrinsically safe circuits, meet the requirements for category 1D
respectively 2D and are marked accordingly.
All the other intrinsically safe circuits may also extend into areas with
combustible dust. However it shall be ensured that the apparatus, connected
to these intrinsically safe circuits, meet the requirements for category 2D and
are marked accordingly.
The module may only be used with the terminal base type 1797-TB3/* or
type 1797-TB3S/* (DMT 98 ATEX E012U)
A warning label shall be installed in immediate proximity of these apparatus:
ATTENTION! Avoid electrostatic charging
