Protection category IP 30 according to IEC 60 529
Note:
We recommend that the network settings are changed before the device is installed
(see section 6).
Note:
To permit the exact temperature measurement with the internal temperature sensor,
an adequate air circulation in the enclosure or server enclosure must be provided,
and the CMC PU III located so that it is adequately supplied with air, and the vent slots
not covered.
If this cannot be implemented, the external temperature sensor from the scope of sup-
ply must be used instead of the internal temperature sensor.
Note:
The separation between the infrared access sensor in the CMC III PU and the reflect-
ing foil must not exceed 15 cm. If necessary, correct the CMC III PU installation loca-
tion appropriately.
