NonStop NS2400 Series Planning Guide

Branch Circuits and Circuit Breakers, Monitored Single-Phase PDUs
In NonStop NS2400 cabinets without the optional rack-mounted UPS, each of the two PDUs
requires a separate branch circuit of these ratings:

Category D circuit breaker is required.
CAUTION: Be sure the hardware configuration and resultant power loads of each cabinet within
the system do not exceed the capacity of the branch circuit according to applicable electrical codes
and regulations.
Select circuit breaker ratings according to local codes and any applicable regulations for the circuit
capacity. Note that circuit breaker ratings vary if your system includes the optional rack-mounted
HP Model R5000 UPS.
North America and Japan: 200 to 240V AC, Modular Single-Phase PDU Power
The NonStop NS2400 cabinet can contain up to 4 1U modular power distribution units (PDUs).
On systems with a UPS, two PDUs are used, occupying a total of 2U of space.
On systems without a UPS, two pairs of PDUs are used. Each pair is mounted back to back so the
two pairs occupy only 2U of space.
The PDU power characteristics are:
PDU input characteristics
• 200 to 240 V AC, single-phase, 24A RMS, 3-wire
• 50/60Hz
• 3.6 m attached power cord
• NEMA L6–30P input plug as shown below:
PDU output characteristics
• 4 15A output circuit breakers
• 4 AC receptacles per PDU - IEC 320 C19 receptacle
type
• 2 extension bars per PDU. Each extension bar contains
7 AC receptacles.
