Transformer transportation restraints removing procedures for UPS with 12-pulse rectifier

The removing procedures of the output transformer transportation restraints of 300kVA UPS with 12-pulse rectifier are the same as those of 300kVA UPS with 6-pulse rectifier. The removing procedures of the transportation restraints of the phase-shifting transformer are as follows:

1.Open the front door and remove the back panel of the side cabinet to reveal the phase-shifting transformer, as shown in Figure 5. Retain the screws.
