Electrical requirements
Line voltage
Line voltage (AC) at the wall power outlet is a function of the local power
utility and your building power distribution network. Voltages outside of
the operating range of the disk array can cause intermittent system errors or
a complete system shutdown. If required, an HP representative and your
electrician can determine the current line voltage and make
recommendations. See
Appendix A
for specific AC line voltage
requirements.
Avoid the use of a line voltage conditioner.
Make sure that a power distribution unit (if used) supports the correct
voltage to support your entire system.
Branch circuit breakers
See
Appendix A
for specific branch circuit requirements for your power
situation.
Three-phase branch circuit breakers
The power cords supplied with each DKC or DKU configured for
three-phase power are sized for connection to a 30-amp circuit.
Single-phase branch circuit breakers
The power cords supplied with each DKC or DKU configured for
single-phase power are sized for connection to a 30- or 50-amp circuit.
Note
30-amp, single-phase power is available by special order only.
