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 - Gain access to the internal components of the Liebert
®
FPC
™
unit by removing the
exterior panels and internal accent panels.
Visually inspect - Be sure wiring and components are not damaged.
Check power connections - Check all power connections for tightness. Refer to Tables 11
through 14 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 FPC.
Initial System Startup
A qualified electrician must be employed to perform the equipment inspection and startup. Liebert
system startup may be arranged by calling your local Emerson sales representative or Emerson
Network Power Liebert Services. In the United States, call 1-800-LIEBERT.
Warranty
A copy of the appropriate checklist (furnished with the equipment) must be completed, signed, dated
and returned to Emerson Network Power. Warranty coverage of the equipment is not effective unless
the checklist has been received by the factory.
!
WARNING
Risk of electric shock and arc flash. Can cause injury and death.
Verify that all incoming line voltage (power) and low-voltage (control) circuits are
de-energized and locked out before performing the internal inspection.
!
WARNING
Risk of improper startup. Can cause equipment damage, personal injury and death.
Hazardous voltages are present during startup procedures. Electrical safety precautions must
be followed throughout inspection and startup.
Equipment inspection and startup should be performed only by properly trained and qualified
personnel wearing appropriate safety headgear, gloves and shoes.
