Important:
The MI does not have a built-in power switch. The system is always pow-
ered when connected to a power source. Vaisala recommends mounting an external
mains switch to control the MI’s power supply (Figure 3.5). The external power switch
should be easy to access. It is also recommended to use a 10A/230V circuit breaker for
power supply.
