IP40 (MCUlite-2 and MCU5)
IP31 (MCU W)
Up to 2000 m
+5 °C to +40 °C
-25 °C to +70 °C (MCUlite-2 and MCU5)
-20 °C to +60 °C (MCU W *)
Relative humidity 80% maximum (non-condensing) for temperatures up to +31 °C.
Linear decrease to 50% at +40 °C
Pollution degree 2 as defined by BS EN 61010-1:2001 section 188.8.131.52.
Normally only non-conductive pollution occurs. Occasionally, however, temporary conduction caused by condensation occurs.
* Storing the MCU W battery at high temperatures is not recommended because it prematurely ages the battery. The maximum recommended times for storage of the MCU W battery are:
- 1 week at +60 °C
- 1 month at +45 °C
- 6 months at +40 °C
- 12 months at +35 °C
