Internal Power Wiring

When cables are used for power wiring, they must be copper and rated at 90° C

(194° F). For frames 13 and 14 drives, power connections between the AC choke

and the NFE converters are typically made using busbars, however, copper cables

may be used.

Drives with Parallel Power Structures

Drives can contain one to six converters. Each converter contains a set of input

power terminals. When parallel power structures are present, you must supply

power to all sets of input terminals on these drives. Refer to Ta b l e 1

and Table 2

on page 3

for the number of converters provided with each drive.

Connect power cables (L1, L2, L3) between the appropriate output terminals of

the AC choke and the input terminals of the power structure. Note that multiple

cables per phase may be required. Refer to Figure 14

and Figure 15 on page 22 for

cable/busbar routing examples.

ATTENTION: The following information is merely a guide for proper installation.

Rockwell Automation, Inc. cannot assume responsibility for the compliance or

the noncompliance to any code, national, local or otherwise for the proper

installation of this drive or associated equipment. A hazard of personal injury

and/or equipment damage exists if codes are ignored.

IMPORTANT

Parallel wiring must have the same cable dimensions, type and routing. Non-

symmetrical wiring may cause unequal loading between the converters and

reduce the drive’s ability to deliver current to the motor.

IMPORTANT

The choke has two sets of output terminals designed for different voltages. Tap

1 is the incoming line connection. Tap 2 or 3 is used to connect to the drive

input. Refer to Table 1

and Table 2 on page 3 for specific tap connections.

IMPORTANT

Busbar alignment should be vertical to allow the maximum flow of cooling air

through the enclosure.
