MCU W-2: IP31
Up to 2000 m
+5 °C to +40 °C
MCU5-2: -25 °C to +70 °C
MCU W-2*: -20 °C to +60 °C
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 18.104.22.168.
Normally only non-conductive pollution occurs. Occasionally, however, temporary conduction caused by condensation occurs.
* Storing the MCU W-2 battery at high temperatures is not recommended because it prematurely ages the battery. The maximum recommended times for storage of the MCU W-2 battery are:
- 1 week at +60 °C
- 1 month at +45 °C
- 6 months at +40 °C
- 12 months at +35 °C
