1.1.3 Unit Preparation
The Liebert
®
FPC
™
may be easily removed from the shipping pallet and installed by customer
personnel. A typical procedure is as follows:
1. Set the palletized assembly in a level area where there is enough room to roll the Liebert FPC off
the pallet onto the floor.
2. Cut the shipping bands.
3. Remove the factory-provided ramp from its shipping position.
One ramp is provided for every five units.
4. Place the ramp adjacent to the pallet to provide a smooth path from pallet to floor.
5. Remove side panels from the Liebert FPC, if supplied. An Allen wrench for the side panels is
furnished in the installation packet.
6. Remove the bolts and two mounting brackets holding the unit to the shipping pallet.
Mounting brackets are located on either side of the unit.
7. Roll the unit off the pallet onto the floor.
8. Roll the Liebert FPC to the installation area. For units to be placed on a raised floor, use care
when positioning unit over the floor cutout to prevent the casters from falling through the cutout.
1.1.4 Location Considerations
The Liebert FPC should be placed near the load(s) it will supply, preferably within the data center.
Equipment location should employ the shortest output distribution cable runs consistent with logical
equipment arrangement and allowance for expansion.
The Liebert FPC is intended for indoor installation in an area with ambient temperatures of 32°F to
104°F (0°C to 40°C) with a relative humidity of 0% to 95% (non-condensing).
Bottom clearance is required for units with bottom entry/exit of cables. This clearance may be
provided by a raised floor at least 6" (150mm) high. Figures 1 and 2 show the typical raised-floor
cutout dimensions for cables and cooling airflow.
When units are not installed on a raised floor, or if the raised floor will not support the unit, optional
floor pedestals may be used. (CSA regulations require Liebert FPC arrangements employing a raised
floor. Non-raised floor applications are not CSA approved.) Units with top cable exit provisions do not
require bottom clearance.
Recommended minimum service clearances are shown in Figure 3. The National Electrical Code
(NEC) requires the indicated front and rear clearances for service access. Clearance above the unit is
required for cooling airflow (exhaust).
As do all electrical devices, the Liebert FPC produces heat under normal operation. (See Table 3.)
This heat must be accounted for when calculating the environmental conditions of the room.

WARNING
Risk of cutting metal bands under tension. Can cause injury and death.
The shipping bands may be under tension. Use appropriate eye, face and hand protection to
safeguard against injury from band backlash.
NOTE
Before maneuvering the unit into its final position, read and follow all advisories in 1.1.4 -
