FP-AIO-600 and cFP-AIO-600
Caution
For Zone 2 applications, install a protection
device across the external power supply and the COM
terminal. The device must prevent the external power
supply voltage from exceeding 42 V if there is a transient
overvoltage condition.
Special Conditions for Hazardous Locations Use in Europe
The cFP-AIO-600 has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0251502X. Each module
is marked
II 3G and is suitable for use in Zone 2 hazardous
locations.
