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.
