MR33 Series (75K-600K) Modular UPS

User Manual

The UPS should be transported by trained professional.

During transporting, please take care and avoid impact or falling off.

If the UPS needs to be stored for a long time after unpacking, it is suggested to package the UPS with

original plastic bag.

The UPS can be transported by motor-driven forklift (as shown in Figure3-3) or manual forklift (as

shown in Figure3-4). While lifting, please keep the UPS center of gravity at that of the forklift and

move slowly and stably.

Figure3-3

Motor-driven forklift

Figure3-4

Manual forklift

When lifting, pay attention to the balance and stable of the UPS.

During moving, keep the UPS vertical and do not put down or uplift suddenly.
