Notes on use in hazardous areas
Do not open the device when the supply voltage is turned on.
Replacing components may impair suitability for Class 1, Division 2 or Zone 2.
The device may only be operated in an environment with pollution degree 1 or 2 (see
IEC 60664-1).
Do not connect or disconnect cables to or from the device when a flammable or
combustible atmosphere is present.
When used in hazardous environments corresponding to Class I, Division 2 or Class I,
Zone 2, the device must be installed in a cabinet or a suitable enclosure.
If a device is operated in an ambient temperature of more than 60 to 70 °C, the
temperature of the device housing may be higher than 70 °C. The device must therefore be
installed so that it is only accessible to service personnel or users that are aware of the
reason for restricted access and the required safety measures at an ambient temperature
higher than 60 °C.
