(front view without front door and panel)

1.All Liebert-supplied cable must be repositioned prior to and while setting the cabinets in their installed location.

2.All interconnection cables and hardware supplied by others.

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

4.The interconnecting output cables between the paralleling cabinet and the UPSes must be the same size and the same length.

5.The location of the system output neutral busbar (connection K) and the ground busbar (connections H, I and J) are shown for a left-access style. For right-access version, these busbars are at opposite locations

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