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 750Series 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).
WARNI NG: 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
3. Insert the four tethered anchor pins. The four pins are inserted in the alpha character, which corresponds to the plate position.
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
ATTENTION: Before adjusting the height of the cart, remove the jackscrew locking
pin. Failure to remove this locking pin will result in equipment damage.
ATT EN TI ON : 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.

PowerFlex 750-Series Service Cart Frames 8…10 Conversion Kit
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).

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
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.
IMPORTANT The two safety clips must be raised when docking
IMPORTANT The four anchor pins must be removed after the

clips during power module removal. Before
changing the height and before transport begins,
release the safety clips from the control cabinet.
service cart is docked. Insert the anchor pins after
the power module is loaded and before transport
of the power module begins.
ATT EN TI ON : Avoid personal injury and equipment damage. Lock wheel casters before removing a power module.
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
• Pinch Point B: When lowering the service cart

Move the Power Module
This label, affixed to
the module chassis,
identifies the center
of gravity.
ATT EN TI ON : Avoid personal injury and equipment damage. Power modules have a
high center of gravity and a Tip-over Hazard exists. To guard against death, serious
personal injury, or equipment damage, do not subject the module to high rates of
Acceleration or Deceleration while transporting. Do not push or pull above the
points that are indicated on the module.
Avoid personal injury. Hazard of pinch point injury exists. Review all product labels
and familiarize yourself with the potential pinch point hazards before Handling
modules. Use caution when moving the modules between the service cart and the
Work stat ion .
IMPORTANT Take precautions when using the service cart to transport a module.
• Use the service cart to move a module a shor t distance to gain access to the
cabinet interior or to service the module.
• Lower the center of gravity by putting the service cart at the lowest level
possible.
• Use the service cart on smooth and level surfaces.
• Avoid sloped and rough surfaces.
