Power Requirements

This section provides information regarding command module AC power requirements, power cord routing instructions, and site wiring conditions.

The AC power source must provide the correct voltage, current, and frequency specified on the manufacturer’s nameplate. Internal AC power units for rackmount cabinets must be able to handle the power requirements for these units (Table 2-7).

Table 2-7		Command Module Power Requirements
Item		Unit of Measure	Requirement
Circuit Breaker		Slow-blow Fuse	3 A per Power Supply
		Nominal Voltage	90 to 264 VAC
		Frequency	50 to 60 Hz
AC Power
		Operating Current	1 A1
	Maximum Surge Current		2 A1

1 Typical current at 240 VAC, 60 Hz at 0.70 power efficiency, 0.99 power factor.

Power Cord Routing

All modules are shipped with two AC power cords that are appropriate for use in a typical outlet in the destination country. Each power cord connects one of the power supplies in a module to an independent, external power source, such as a wall receptacle or uninterruptible power supply (UPS). If you have a rackmount cabinet with internal power cabling, such as a ladder cable, you do not need these power cords.

A rackmount cabinet can have up to two AC power distribution boxes with separate power cords (Figure 2-3). To ensure redundancy, each power cord must connect to an independent, external power source. Each AC power distribution box has a ladder cable that runs up the inside of the cabinet and connects to one of the power supplies in each module.

Figure 2-4 on page 2-10shows the power cords and receptacles for domestic (inside USA) and international use (outside USA).
