Important:
The cables must conform to local standards.
Install a power switch outside the humidifier to completely isolate
the mains power supply, with earth (fault protection 30 mA) the earth
cable must be mechanically protected and not exposed. The unit is
not compatible with IT power supply systems. The single-pole current
breaking switch must be fitted upstream of the device.
