Risk of improper handling. Can cause equipment damage, injury or death. The Liebert PPC is heavy; its weight ranges from 400lb. (182kg) to 2450lb. (1111kg) The unit should not be loosened from the shipping pallet until after all handling by forklift or pallet jack is completed ELECTROMAGNETIC COMPATIBILITY—The Liebert PPC complies with the limits for a Class A digital device,... -
Page 6: Installation Instructions
Inspect for damage or signs of mishandling before unpacking the unit(s). Check the Shock-Watch indicator. If the Liebert PPC was shipped in an export crate, open the shipping crate carefully. (Use care to avoid puncturing the container with sharp objects that would damage the contents.) Remove the packing and vapor barrier and inspect the equipment for any obvious shipping damages. -

• Phase C (wire 432) to X3 The sidecar neutral (Wire 442) and ground (Wire 452) conductors are connected to the Liebert PPC main ground busbar (see unit wiring diagram). For Liebert PPC’s without transformers, the sidecar phase and neutral conductors are connected to the corresponding output power distribution terminal blocks inside the main unit. -
Page 14: Input Power Connections
For units with a transformer, the main input feeder should consist of 3-phase conductors and one (safety) ground conductor (3W + G). For units without a transformer, the main input feeder must consist of 3-phase conductors, one neutral and one (safety) ground conductor (4W + G). Vertiv | Liebert ® ™... -

1.3.2 Junction Box Installation (If Used) Main input (power) and low-voltage (control) junction boxes are available for the Liebert PPC to simplify customer connections. Shipping Arrangements—The junction boxes, if used, can either be shipped with the system or can be advance-shipped for installation during the roughing-in stage of new construction. -

Page 26: System Grounding
1.3.4 Grounding Electrode Conductor (Units With Transformer) Required by code—The Liebert PPC with transformer must be grounded according to the safety practices of NEC 250-26. A local grounding electrode conductor is recommended in addition to the equipment safety ground, which is normally run with the input power conductors. -

Air circulation—Prevent restriction of airflow under the raised floor by running the flexible conduits flat on the sub-floor, in parallel paths. For best performance, the Liebert PPC should be located as close to the load as practical. Initial system output loading should be between 50% and 75% of rated capacity. This allows the addition of future loads without immediately investing in another power conditioner. -

The shunt-trip solenoid opens the Main Input Breaker, which de-energizes the Liebert PPC. Multiple-unit shutdown—When more than one Liebert PPC is installed by the user, a typical requirement is that actuation of a single device (REPO, for example) must shut down all Liebert PPC’s. The low-voltage control circuits of all standard Liebert PPC systems are designed to meet this requirement. -

NOTE The Liebert PPC transformer has input voltage taps for each input phase. The taps are arranged in 2-1/2% or 5% intervals ranging from -10% to nominal to +5%. This permits the transformer to provide the proper output voltage for a range of input voltages. Should it be necessary, the tap arrangement may be changed to match the input voltage: •... -
