Do the power cables connected to the new UPS cabinet need phase verification?

Thread Content

Since both transformers in the workshop are to be overhauled and power needs to be cut off, the UPS cabinet in the control room needs to be powered by three-phase electricity from another workshop in order to keep it functioning. After I turn off the transformers and the UPS starts working, I will then connect the power cable from the other workshop to the UPS cabinet. Do I need to check the phase alignment before making this connection?
