18 Site Planning Guide
NOTE: Protective ground is also known as safety ground or chassis ground.
•
Circuit overloading – Power circuits and associated circuit breakers must provide enough power
and overload protection.
NOTE: To prevent damage to the base system, isolate its power source from large switching loads,
such as air-conditioning motors, elevator motors, and factory loads.
• Power interruptions – The base system can withstand these applied voltage interruptions:
• Input transient – 50 percent of the nominal voltage
• Duration – One half-cycle
• Frequency – Once every 10 seconds
• Power failures – If a total power failure occurs, the base system automatically performs a
power-on recovery sequence without operator intervention.
AC Power Input
Table 17 provides the AC power input for the QD6000 and QD7000 base systems.
NOTE: Each power supply contains one 15-A slow-blow fuse.
Power Factor Correction
Power factor correction is applied within the power supply, which maintains the power factor of the
QD6000 and QD7000 base systems at greater than 0.95 with nominal input voltage.
AC Power Cords and Receptacles
Each QD6000 and QD7000 base system ships with two AC power cords, which use the standard AC
outlets in the destination country. Each AC power cord connects one of the power supplies in the
drive tray to an independent, external AC power source, such as a wall receptacle, or to any
uninterruptible power supply (UPS).
If you have a cabinet with internal power cabling, such as a ladder cord, you do not need the AC
power cords that are shipped with the QD6000 and QD7000QD6000 and QD7000 base system.
