Special conditions 
The devices must be installed in a protected environment in 
accordance with the specific conditions on the test certificate. 
Pollution degree 3 (in accordance with IEC 60664-1) should 
not be exceeded for the macro environment of the device. 
The devices are in accordance with IP degree of protection 
IP 66 / IP 67. If the device is installed properly, this 
requirement is met 
by the housing as standard. 
When connected to the power supply / not connected to the 
power supply, the electrical circuits must not exceed 
overvoltage category III / II. 
For input limits or analog input limits, see the chapter titled 
"Limit value tables" on page 13. 
 
Devices with extended EMC-protection 
(SIL and NAMUR design) 
For the operation in the ignition protection type "Intrinsic 
safety / Intrinsically safe", the current circuits on the device 
must be connected over approved, electrically isolated safety 
barriers.
