TARTUP
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.
9.1 XDF Startup Inspection Checklist
9.1.1 Site 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.
