Drive Module Power Requirements

E3300 Drive Module

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 this unit (Table 11).

Table 11 E3300 Power Requirements

Item	Unit of Measure		Requirement
Circuit Breaker	3.0 A (slow-blow fuse per power supply)
		USA	International
	Nominal Voltage	90 to 136 VAC	198 to 257 VAC
Drive Module AC	Frequency	50/60 Hz	50/60 Hz
Power
	Idle Current	2.9 A1	1.3 A1
	Maximum Operating Current	3.2 A1	1.5 A1
	Maximum Surge Current	4.5 A1	2.1 A1

Power Connections

The drive module uses two AC power cords (one for each power supply). In order to meet power requirements and maintain power redundancy, you must connect the drive module to either 90-136 VAC or 198-257 VAC, 15 A circuits as described below.

•Redundant power, 90-136 V – Connect as follows:

•If three or less drive modules are connected to a command module, use two 90-136 V, 15 A circuits. Connect one power supply from each drive module to one circuit and the other power supplies to the second circuit.

•If more than three drive modules are connected to a command module, use four

90-136 V, 15 A circuits. Connect one half of the drive modules to two circuits and the remaining drive modules to the other two circuits. Make sure that each drive module connects to two different circuits (one per power supply).

•Redundant power, 198-257 V – Use two 198 V-257 V, 15 A circuits. Connect one power supply from each drive module to one circuit and the other power supply to the second circuit.
