Product Description

1.4.3Positioning the Liebert XDC with Floor Stand

Install the Liebert XDC according to the site-specific documentation and secure the unit to the floor.

The Liebert XDC can be installed near a wall or another Liebert XDC. There must be at least 3 feet (914mm) clearance in front of the Liebert XDC for service access. When the Liebert XDC is combined with the optional water/glycol floor stand, Liebert recommends leaving 3 feet (914mm) of clearance on the left side of the unit.

A Liebert XDC on a floor stand is 102 inches (2591 mm) high (see Figure 9). The unit can be raised or lowered 1.5 inches (38.1 mm) with the leveling feet.
