Chapter 4 Mechanical and Electrical Installation
Component Removal
Requirements
This section outlines which components must be removed to install each
PowerFlex 755T product. Each figure illustrates the minimum requirement to
allow adequate access to join and anchor the enclosures, and to interconnect
bus bars. All modules can be removed however to facilitate installation further.
With all modules removed, it is easier to place, align, join, anchor, and
interconnect the enclosures.
During installation, it is recommended that you designate a secure temporary
storage area for the components that you remove from the enclosure. LCL
filter modules and power modules present a tip-over hazard when removed
from the enclosure. Measures must be taken to ensure that modules are stored
in such a way that they do not pose a hazard.
Temporary Component Storage
Do not store components in active isles or work areas. A dedicated area
designated for the temporary storage of the components that are removed
during the installation process is recommended. Loose components can be
hazardous and easily damaged.
Recommended Equipment and Accessories
Equipment is available that is designed to help you safely handle major
components. The following equipment is recommended:
• PowerFlex 750-Series module service cart, catalog number 20-750-
MCART1, publication 750-IN105
• PowerFlex 755T DC precharge module lift, catalog number 20-750-
MCART2, publication 750-IN105
• PowerFlex 750TM power and LCL filter module storage hardware,
catalog number 20-750-MINV-ATIP, publication 750-IN106
• PowerFlex 755T power module service ramp, catalog number 20-750-
MRAMP1, publication 750-IN108
For a list of Commonly Used Tools see page 16.
IMPORTANT LCL filter modules and power modules are labeled to indicate their
designated position in the product enclosure. Always reinstall modules in
their corresponding factory-designated position. Make note of these labels
during component removal. See Figure 18
for label locations.
IMPORTANT The service ramp is used only with power module when the cabinet
is mounted directly to the floor. Do not use the ramp to remove LCL
filter modules from the cabinet. Review service ramp instructions
before using.
