2. Connection of the system
2.1 Power transformers
•
A step down transformer, (XAT-2) is normally shipped together with this generator for installation.
This transformer can provide proper power input for UD150L-30 FX/EX generator, YSF/RS table
system, HMS/AID high-speed starter, and other peripheral accessories.
•
There are two other transformers in UD150L-30 FX/EX generator are power related, T1 and T2
transformer. It is necessary to change taps for these two transformers according to the supplied input
from XAT-2 before proceeding.
(1) T1 transformer,
For example, if the incoming power is three-phase 400V from XAT-2, connect AIN-0 to –A200 and
AIN-2 to A200.
(2) T2 transformer,
Connect T2-0 to –200 and T2-2 to 200 base on the same assumption as (1).
