Special Requirements 
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) must not 
be exceeded for the macro environment of the device. 
The devices are in accordance with IP rating 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. 
 
2.5.3  Repair 
Devices of explosion protection class of "flameproof 
enclosure / Flameproof enclosure" are equipped with 
flameproof open joints in the housing.  
Contact ABB before commencing repair work.
