Installation Instructions

1.1.3Unit Preparation

The Liebert FPC may be easily removed from the shipping pallet and installed by customer person- nel. 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 and entire cable assembly off the pallet onto the floor.

2.Cut the shipping bands.

! WARNING

The shipping bands may be under tension and may snap violently when cut. Use eye, face and hand protection to guard against injury when the bands are cut.

3.Remove the factory-provided ramp from its shipping position.

One ramp is provided for every five units. Ramps are packed either in front of or on top of a set of cable reel(s).

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.If cables are on wheeled cable reel(s), remove the bolts holding the reel(s) to the pallet and remove the nailed-on shipping blocks.

8.Roll the unit off the pallet onto the floor, carefully guiding the cable reel(s) after it.

9.Roll the FPC and the cable reel(s) 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.

! CAUTION

Before maneuvering the unit into its final position, read and follow all advisories in 1.1.4 - Location Considerations.

1.1.4Location 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 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 pro- vided 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 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). Units with optional distribution monitoring also require service access clearance on the left side.

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.
