Installation Instructions

PowerFlex® 750-Series Roll-Out Cart

ATTENTION: Because drive installations can vary, the PowerFlex

750-Series Roll-out Cart may require adjustment prior to use. Refer to the
PowerFlex 750-Series AC Drive Installation Instructions, publication
750-IN001 for detailed setup information. Familiarize yourself with all
hazards associated with using the Roll-out Cart before attempting to
remove the drive from the cabinet.

ATTENTION: The Roll-out Cart is used with a drive that has a high center
of gravity and a tip over hazard exists. To guard against death, serious
personal injury, and/or equipment damage, do not subject the drive to
high rates of acceleration or deceleration while transporting. Do not push
or pull above the points indicated on the drive.

ATTENTION: To avoid an electric shock hazard, verify that the voltage on
the bus capacitors has discharged completely before servicing. After
removing power to the drive, wait 5 minutes for the bus capacitors to
discharge. Measure the DC bus voltage at the DC+ and DC- TESTPOINT
sockets on the front of the power module. The voltage must be zero.

ATTENTION: HOT surfaces can cause severe burns. After disconnecting
power allow time for cooling.

ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive
parts and assemblies. Static control precautions are required when
installing, testing, servicing or repairing this assembly. Component
damage may result if ESD control procedures are not followed. If you are
not familiar with static control procedures, reference Guarding Against
Electrostatic Damage, publication 8000-4.5.2 or any other applicable ESD
protection handbook.

ATTENTION: Hazard of permanent eye damage exists when using optical
transmission equipment. This product emits intense light and invisible
radiation. Do not look into module ports or fiber optic cable connectors.

Finding Specific Information

IMPORTANT

Take precautions when using the Roll-out Cart to move the drive.

• Only use the Roll-out Cart to move the drive a short distance in order to

gain access to the cabinet interior.

• Do not attempt to move the drive on the Roll-out Cart with the handle

alone. The Roll-out Cart handle is designed for positioning the empty
cart.

• Only use the cart on a smooth and level surface.

• Ensure the path for the cart is clear of debris and obstacles.

• Avoid sloped and rough surfaces.

• Always move the drive slowly.

For detailed information on using the Roll-out Cart with the drive refer to the
PowerFlex 750-Series Installation Instructions, publication 750-IN001 available

Adjust Roll-Out Cart Height Using Threaded Studs and Nuts

The height of the Roll-out Cart deck can be adjusted using the threaded leveling
studs and nuts.

• Maximum height = 155.5 mm (6.1 in.)

• Minimum height = 116 mm (4.6 in.)

• Adjustment range = 30 mm (1.2 in.) up, 9.5 mm (0.4 in.) down from the

factory setting of 125.5 mm (4.9 in.)

1. Loosen and back off the top nuts on the four threaded leveling studs ➊.

125.5 +30.0/-9.5
(4.9 +1.2/-0.4)

2. Turn the bottom supporting nuts to raise or lower the cart deck ➋. Right

hand nut rotation lowers the deck. Left hand rotation raises the deck.

Make uniform half-turn adjustments to each of the four threaded studs in
an alternating pattern to help prevent binding and maintain a level
orientation.
