2.0 EQUIPMENT INSPECTION AND STARTUP
2.1 Internal Inspection
A detailed internal inspection should be performed after the unit is in place and before it is energized, to ensure
trouble free startup. The same internal inspection should be carried out when performing preventive
maintenance.
Open the unit—Remove the exterior panels to gain access to the Liebert PPC’s internal components.
Visually inspect—Be sure wiring and components are not damaged.
Check power connections—Check all power connections for tightness. Refer to Tables 8 through 11 for torque
requirements of all electrical connections.
Perform formal detailed inspection—Follow the procedures described in 3.0 - INSPECTION AND STARTUP
CHECKLIST when performing detailed inspection.
2.2 Startup
Checklists—Follow the detailed step-by-step checklist (3.0 - INSPECTION AND STARTUP CHECKLIST)
when installing and starting up the Liebert PPC.
Initial system startup—A qualified electrician should be employed to perform the equipment inspection and
startup. Liebert system startup may be arranged by calling your local Liebert sales representative or Vertiv
Services. In the USA, call 800-543-2378.
Warranty effectivity—A copy of the appropriate checklist (furnished with the equipment) must be completed,
signed, dated, and returned to Vertiv. Warranty coverage of the equipment is not effective unless the checklist is
received by the factory.

Verify that all incoming power and control circuits are de-energized and locked out before performing the
