Cable Lengths: Floor to Connection Point Inside UPS

To help calculate the total cable length required, refer to Table 36 for the distance from the floor to
selected connection points inside the Liebert NX. Determine the cable length required to reach the
Liebert NX, then add the appropriate length from the table and adequate slack for repair and
maintenance.
