Rockwell Automation SD3100 DISTRIB PWR SYS SD3100 DC PWR MODULE - Manual (Page 36)

3-2 SD3100 Power Modules
3.2 Physically Installing the Power Module
To move and position the unit at your site, follow the instructions given in publication
2100-5.5, titled
Instructions - Receiving, Handling, And Storing Motor Control Centers.
This publication contains instructions for the proper handling, moving, and positioning
of the Power Module.
After the Power Module is properly positioned, follow the instructions given in
publication 2300-5.1, titled
Bulletin 2300 Family of Drive Systems Hardware. This
publication describes how to splice busbars, how to attach the Power Module in a
multiple drive configuration, and how to join MCC sections together (if necessary).
3.3 Wiring AC Input Power to the Power Module
To wire AC input power to the Power Module, you will need to do the following:
• install an isolation transformer
• select and provide appropriate input power wire
• prepare the drive enclosure
• connect the input power
Take precautions to separate AC and DC power leads from signal leads, such as
resolver or tach wiring, to minimize electromagnetic interference. Wiring should
comply with ANSI/IEEE Standard 518. Follow the instructions on separating wiring
found in the wiring diagrams and in instruction manual D2-3115.
Refer to figure 2.5 (1250A units), figure 2.7 (1650A units), or figure 2.9 (3000A units)
for component and terminal locations.
3.3.1 AC Input Wire Selection
Table 3.1 shows the recommended AC input wiring. Note that this table reflects
NFPA 70, 75° C wiring. Refer to the applicable local codes for specific guidelines.
!
ATTENTION: The Power Module is at line voltage when connected to
incoming AC power. Disconnect, lock out, and tag all incoming power to
the drive before performing the following procedures. Failure to observe
this precaution could result in severe bodily injury or loss of life.
!
ATTENTION: The user is responsible for conforming with all applicable
local, national, and international codes. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
