Confirmation of power supply for agricultural vinyl house

I purchased it because it is used for phase detection at the time of connecting a backup power supply of a large vinyl house for agriculture. Although it rarely happens, if the power failure is likely to be prolonged due to heavy snow or the like, it is necessary to connect the three phase AC generator to control the control unit even with only the control power supply. In this case, there is a risk of connecting the generator to the opposite phase and connecting it to the opposite phase and breaking the equipment, so we decided to connect before confirming the phase rotation in advance. I chose it because the reason why I chose it is inexpensive and the fear of short circuit etc. is low. The alligator mouth is structured to prevent the short circuit because the outside is covered with plastic. The terminal block can be connected if you remove the cover, but the connection seems to be a bit difficult for the NFB terminal. I think that it is better to check where you can connect safely in advance. A 200 V short circuit is dangerous because a large current flows considerably. Although there are goods that can be checked from the top of the covering, the price will be multiplied by 2 to 3. If you prepare in advance, I think that you can safely use this product. Moreover, I think that it is good that batteries are unnecessary.
