NonStop NS16000 Series Planning Guide (H06.11+)

International: 380 to 415 V AC, Monitored Three-Phase PDUs

The international PDU power characteristics are:

PDU input characteristics

• 380 to 415 V AC, 3-phase Wye, 16A RMS, 5-wire

• 50/60Hz

• IEC309 5-pin, 16A input plug

• 6.5 feet (2 m) attached harmonized power cord

PDU output characteristics

• 3 circuit-breaker-protected 16A load segments

• 3 AC receptacles per PDU (1 per segment) - IEC 320

C19 16A receptacle type

Branch Circuits and Circuit Breakers, Monitored Three-Phase PDUs

Modular cabinets for the NonStop NS16000 series system that use a three-phase power

configuration with monitored three-phase PDUs contain two PDUs. In cabinets without the optional

rack-mounted UPS, each of the two PDUs requires a separate branch circuit of these ratings:

Amps (see following “CAUTION”)Volts (Phase-to-Phase)Region

30200 to 240North America and Japan

380 to 415International

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.

Branch circuit requirements vary by the input voltage and the local codes and applicable regulations

regarding maximum circuit and total distribution loading. Select circuit breaker ratings according

to local codes and any applicable regulations for the circuit capacity.

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 rackmounted

UPS.

Modular Three-Phase PDUs

Two three-phase modular power distribution units (PDUs) are installed to provide redundant power

outlets for the components mounted in the modular cabinet. Each 1U rack-mounted modular PDU

comes with four modular PDU extension bars. The PDUs are oriented facing each other within the

rack. Each PDU has 28 AC receptacles, six circuit breakers, and an AC power cord. The PDU is

oriented with the AC power cord exiting the modular cabinet at either the top or bottom rear

corners of the cabinet, depending on the site's power feed needs.

For information about specific characteristics for PDUs factory-installed in modular three-phase

cabinets, refer to
