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).
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.
