Remove bottom supporting plates

Figure1.7

The bottom supporting plates of the UPS are the same, In above figure, we take 80kVA-120kVA UPS
as an example to illustrate.

Loosen the brake of all the wheels or heighten the 4 supporting feet (as shown in Figure1.8).

The wheels of 10kVA-60kVA is equipped with brake, the wheels of 80kVA-120kVA is equipped with
supporting foot.
