1.1.3 Unit Preparation
The Liebert PPC may be removed from the shipping pallet and installed by customer personnel. A typical
procedure is:
1. Set the palletized assembly in a level area, where there is enough room to roll the unit and entire cable assembly off the
pallet onto the floor.
2. Cut the shipping bands.
3. Remove the factory-provided ramp from its shipping position—packed in front of the unit. Place the ramp adjacent to the
pallet to provide a smooth path from pallet to floor.
4. Remove side and rear panels from the module. An Allen wrench for the side panels is furnished in the installation packet.
(Carefully disconnect panel ground wires by pulling the easy-disconnect terminals at the unit frame.)
5. Remove the bolts holding the unit to the shipping pallet. (Located in each of the four bottom corners.)
6. Remove shipping blocks from under unit, then remove chocks from all casters.
7. Roll unit off pallet onto floor.
8. Roll unit to its installation location. For units located on a raised floor, use care when positioning unit over the floor cutout
to avoid casters falling through the cutout.
1.1.4 Location Considerations
The Liebert PPC should be located within the computer room, and/or close to the load(s) which it is supplying.
Equipment Location—Should employ the shortest output distribution cable runs consistent with logical
equipment arrangement and allowances for future additions.
Operating Environment—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—Required for exit of cables/conduit and/or for cooling air flow. This clearance is
automatically provided by a raised floor (6 in. / 150 mm minimum height). Figures 1 and 2 show typical
raised-floor cutout dimensions.
When units are not located on a raised floor (or if the raised floor is not adequate to support the unit), optional
floor pedestals may be used. (Non-raised floor applications are not CSA approved.) Units with top cable exit
provisions and side vents do not require bottom clearance.
Recommended Minimum Service Clearances—Shown in Figure 4. The indicated clearances at the front and
one other side or rear of the unit are required for service access by the National Electrical Code (NEC)
(Article 110-26). Clearance above the unit is required for cooling air flow (exhaust).
Heat Output—As do all electrical devices, the Liebert PPC produces heat under normal operation. (See Table 1.)
This heat output should be included when calculating the environmental conditions of the room.
WARNING
Risk of cutting bands under tension. Can cause injury or 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 the following paragraphs in
1.1.4 - Location Considerations.
