9.0STARTUP

Before plugging in your electronic equipment, make sure that all power switches are in the OFF posi- tion.

•Be certain there are no obstructions, wire bundles, manuals, trash, etc., in front of or on either side of the XDF. Make sure all doors are shut and sealed properly.

•Plug the XDF’s 120V power cord into a dedicated utility circuit.

•Plug the XDF’s 208V power cord into a dedicated utility circuit.

9.1XDF Startup Inspection Checklist

9.1.1Site Conditions

___ 1. Confirm at least 36 in. (915mm) clearance in front of the XDF, on the right side and behind the unit. No left-side clearance required.

___ 2. Confirm at least 36 in. (915mm) clearance above the unit (self-contained, air cooled units only; water/glycol units do not require clearance above).

___ 3. Confirm site ventilation provisions:

___	Sufficient ambient space to dissipate heat rejected by the XDF (self-contained, air cooled
	units).
___	Ambient temperature range is 35°F to 104°F (1.6 to 40°C).

___ 4. Ensure that the XDF is level.

___ 5. Confirm condensate drain tube is connected to a drain and will drain properly.

___ 6. Secure all electrical connections inside the XDF.

___ 7. Confirm that the dedicated circuits for the XDF’s compressor and fans are separate from the circuit for the UPS (not same duplex).

___	XDF requires a 120V/60Hz/15A, single-phase, 2-wire plus ground circuit.
___	Record the fan working input voltage 120VAC (±10%): ____________________
___	XDF requires a 208V/60Hz/30A, three-phase, 4-wire plus ground circuit.
___	Record the compressor working input voltage 208VAC (±10%): ____________________
___	Check UPS (if provided) nameplate for input electrical requirements.

___ 8. Examine the positioning of equipment inside the cabinet.

___	Prevent short cycling of airflow - no spaces larger than 1U between electronic devices.
___	Spaces larger than 5U at top of rack are covered with blanking panels.
___	Heaviest equipment installed near the bottom of the cabinet.

___ 9. Check cabinet seals—No gaps, loose cables, air leaks:

___	Door gaskets intact / free of damage. Close front and rear doors and confirm no visible
	seal violations.
___	Side panels and the frame have uniform sealing.
___	Cable entrance points are sealed.

___ 10. Determine whether the UPS, if one is installed in the XDF, has fully charged batteries.

NOTE

The UPS’s batteries may require recharging before it can fully supply your equipment’s power needs for the rated time if utility power fails.

To charge the UPS batteries before using the unit, you can apply power to the UPS module while installing equipment or making adjustments.

Refer to the UPS manual for preparation for startup, details of UPS operation and the meaning of LED indicators.
