3.3 DETAILS OF CHECKING
3.3.1 Power Supply Checking
3.3.1.1 Checking the power supply
Check whether the power supply satisfies the following specifications:
200VAC +10%, -15%, 50/60Hz ±1Hz, 3φ
or 220VAC +10%, -15%, 60Hz±1Hz, 3φ
3.3.1.2 Phase rotation
Connect input terminals U, V, and W to R, S, and T of the phase
rotation sensor, respectively, and check that the disk of the phase
rotation sensor turns clockwise.
