Figure 1. Installing external main switch

CAUTION The MI does not have a built-in power switch. The system is always powered when connected to a power source. Vaisala recommends mounting an external mains switch to control the MI’s power supply, as shown in the previous figure. Make sure that the external power switch is easy to access. It is also recommended to use a 10A/230 V circuit breaker for power supply.
