11.5 EEX "ia" design for VT4A/ST4A and
VR4A/SR4A (fieldbus)
Important
The devices may only be operated in explosive areas if the
housing covers have been fully closed.
EC type-examination test certificate
TÜV 01 ATEX 1771
Designation
II 2G EEx ia IIC T4
II 2D T85 °C ... T med IP 67
The hazardous area design is based on the PTB's FISCO model
(FISCO = fieldbus intrinsically safe concept).
