2.2.- Utilizando un multímetro comprobar que la correspon-
dencia de las fases entre los SAIs del sistema es la siguiente:
ENTRADA DE RED AL SAI
Entrada L1 SAI1 = Entrada L1 SAI2
Entrada L2 SAI1 = Entrada L2 SAI2
Entrada L2 SAI1 = Entrada L3 SAI2

ENTRADA DE BYPASS AL SAI

Bypass L1 SAI1 = Bypass L1 SAI2
Bypass L2 SAI1 = Bypass L2 SAI2
Bypass L2 SAI1 = Bypass L3 SAI2
Bypass N SAI1 = Bypass N SAI2

SALIDA DEL SAI

Salida L1 SAI1 = Salida L1 SAI2
Salida L2 SAI1 = Salida L2 SAI2
Salida L2 SAI1 = Salida L3 SAI2
Salida N SAI1 = Salida N SAI2
2.3.- Cerrar los interruptores de bypass y salida del SAI1 y
sólo el de bypass del SAI2.
Comprobar que no existe ninguna diferencia de potencial en-
tre la salida del sistema y la entrada de bypass del SAI2.( Fig.2)

2.2.- Using a Multimeter check the exact correspondence of
the connections between the phases of the UPS, as follows:
UPS MAINS INPUT
L1 input UPS1 = L1 input UPS2
L2 input UPS1 = L2 input UPS2
L3 input UPS1 = L3 input UPS2
UPS RESERVE LINE
L1 reserve UPS1 = L1 input UPS2
L2 reserve UPS1 = L2 input UPS2
L3 reserve UPS1 = L3 input UPS2
N reserve UPS1 = N input UPS2
UPS OUTPUT
L1 output UPS1 = L1 output UPS2
L2 output UPS1 = L2 output UPS2
L3 output UPS1 = L3 output UPS2
N output UPS1 = N output UPS2
2.3.- Close the reserve and output circuit breakers of the
UPS1, close the reserve circuit breaker of the UPS2.
Verify that there is no difference between output and re-
serve voltage of the UPS2.(Fig.2)
