NOTES:

1. All Liebert-supplied cable will need to be repositioned prior to and while setting the cabinets in their

installed location.

2. All interconnection cable and hardware supplied by others.

3. AC connections must be made to the UPS modules before attaching paralleling cabinet to UPS modules.

4. Utility AC source neutral not required for maintenance bypass/transformer cabinet type CR1.

5. Paralleling cabinets must between both UPS modules.

6. Refer to the individual drawing of each piece of equipment for additional details
