PowerFlex 750-Series Service Cart Frames 8…10 Conversion Kit
Bulletin Numbers 20G and 21G
This publication provides basic information to disassemble the 20-750-MCART1 service cart and attach the 20-750-MPLT755T frame 8…10
conversion kit for use with PowerFlex 750-Series frame size 8…10 modules, bulletin numbers 20G and 21G.
The PowerFlex® 750-Series service cart was initially designed to handle and transport PowerFlex 755T modules that are used with PowerFlex 750-
Series products with TotalFORCE™ control. The frames 8…10 conversion kit allows the PowerFlex 750-Series service cart to be converted to a
service cart capable of removing the power modules in the PowerFlex 750-Series frame 8…10 product size.
To use the PowerFlex 750-Series frames 8…10 module conversion kit catalog number 20-750-MPLT755T, you must first follow the instructions to
unpack and stage the PowerFlex 750-Series service cart 20-750-MCART1. Some disassembly of the PowerFlex 750-Series service cart will be
required.

Install the Frames 8…10 Conversion Kit
To install the frames 8…10 conversion kit to the service cart, complete these steps.
1. Use the T45 hex bit to attach the six M10 bolts of the left and right side base extenders to the outside of the carriage assembly.
Torque the bolts to 19.8 N•m (175 lb•in).
2. Use the 13 mm socket to attach the six M8 nuts for the frames 8…10 bridge plate to the base extenders.
Torque the nuts to 10.2 N•m (90 lb•in).
3. Insert the four tethered anchor pins. The four pins are inserted in the alpha character, which corresponds to the plate position.
WARNING: If using position A, the two safety clips (one left and one right) need to be flipped up. This allows the bridge plate to
successfully mate with the base extenders.
TIP The bolts on the base extender are used to select positions A, B, or C for the frame 8…10 conversion plate.
For more information on which position is best suited for your application, see Adjust the Service Cart on page 9.
EXAMPLE The plate being in position A, results in the four anchor pins being inserted into the four position A locations.

Adjust the Service Cart
The height and reach of the service cart carriage assembly is adjustable.
Height
The jackscrew adjusts the height of the carriage assembly. Clockwise
rotation raises the carriage assembly and counterclockwise rotation
lowers the carriage assembly.
To make height adjustments quickly, use an electric hand drill fitted
with a 25 mm socket. An electric drill with a torque rating of 11.3 N•m
(100 lb•in) or higher is recommended. Height is from 0 mm (0 in.) to
137 mm (10.2 in.), where 0 mm (0 in.) is the lowest possible cart
position.
Reach
The frames 8…10 bridge plate sits on the base extenders. To adjust the
reach of the carriage assembly, remove the M8 nuts and the four
tethered anchor pins. Reposition the frames 8…10 bridge plate into an
available slot (A, B, or C).
The M8 nuts must be reattached and torqued to 10.2 N•m (90 lb•in)
when a position change is performed. After the nuts are torqued, the
four tethered anchor pins must be reinserted into the corresponding
slot (A, B, or C).
ATTENTION: Before adjusting the height of the cart, remove the jackscrew locking
pin. Failure to remove this locking pin will result in equipment damage.
ATTENTION: Avoid equipment damage. The left and right safety clips must be flipped up before the service cart is lowered. Failure to due so will result in
equipment damage. See Service Cart Requirements and Safety for Power Module Removal on page 10 for more information.

Service Cart Requirements and Safety for
Power Module Removal
The frames 8…10 service cart is fully adjustable to suit your
need. If adjustments are needed to the reach or height of the
bridge, see section Adjust the Service Cart on page 9 for more
information.
The converted frames 8…10 service cart is designed with two
additional safety features. First there are two safety clips used
during the removal of a power module that anchor the service
cart to the control cabinet. Second, it is equipped with four
anchor pins that secure the power module to the service cart
for transport. The image shows the location of these safety
features.
The addition of the frames 8…10 conversion kit to the
PowerFlex 750-Series Service Cart poses additional pinch
hazards. Be sure to familiarize yourself with the other pinch
hazards listed in the PowerFlex 750-Series Service Cart and
DCPC Module Lift, publication 750-IN105.
•Pinch Point A: When loading or unloading the
power module, keep this area clear for the power
module. The power module will make direct contact
with the service cart when full extracted.
•Pinch Point B: When lowering the service cart
bridge, keep this area clear. The bridge will make
direct contact with the carriage assembly when the
service cart is lowered.
IMPORTANT The two safety clips must be raised when docking
to the control cabinet. Lower and lock the safety
clips during power module removal. Before
changing the height and before transport begins,
release the safety clips from the control cabinet.
IMPORTANT The four anchor pins must be removed after the
service cart is docked. Insert the anchor pins after
the power module is loaded and before transport
of the power module begins.
ATTENTION: Avoid personal injury and equipment damage. Lock wheel casters before removing a power module.
ATTENTION: Avoid personal injury. Do not remove or
disable the touch guards. Pinch points exist between
the movable parts of the service cart. Review all
product labels and familiarize yourself with the
potential pinch-point hazards before you operate the
service cart.
