Unpacking and Inspecting
Overview Before leaving the factory, the controller has been tested mechanically and
electrically.
Immediately upon receiving the controller, remove the packing and check
for possible shipping damage. Report any damage immediately to the
claims offi ce of the carrier.
After unpacking, check the items received against the Bill of Lading to
ensure that the nameplate description of each item agrees with the material
ordered. Inspect the controller for physical damage as stated in the Rockwell
Automation Conditions of Sale.
All claims for breakage and damage, whether concealed
Remove all packing material, wedges or braces from within the controller.

or obvious, must be made to the carrier by the customer
as soon as possible after receipt of the shipment. Rockwell
Automation will render reasonable assistance in the
securing of adjustment for such damage claims.
If any part of the equipment will not be installed when it is unpacked, it
should be stored in a clean dry place. The storage temperature must be between -20 °C (-4 °F) and 75 °C (167 °F) with a maximum humidity of 95%
non-condensing.

Transportation and Handling
Overview The controller sections are shipped on wooden skids bolted to the cabinetry.
Lifting angles are installed at the top of the cabinetry . The controller sections
must be maintained in the upright position during any handling.
Ensure that the load rating of all lifting equipment is
suffi cient to safely raise the controller sections. Refer to
the packing slip for shipping weights.
Round rollers can be used to assist in moving the equipment to the installation
site. Once at the fi nal site, rollers can be used to place the sections in their
desired position.
Care must be exercised when using either a forklift or the
pipe rolling technique for positioning purposes to ensure
that the equipment is not scratched, dented or damaged
in any manner. Always exercise care to stabilize the
controller during handling to guard against tipping and
injury to personnel.
It cannot be stressed how important it is that the customer
I M P O R T A N TI M P O R T A N T
installation duties are performed correctly. Any errors
will likely cause delays in commissioning or damage to
the equipment.

3-2 Transportation and Handling
Cabinet Handling Instructions When lifting the Bulletin 7712 OneGear™ cabinet, the lifting instructions
specifi ed below must be followed.
Overhead Lifting Method
1. Verify that the front/back lifting channels and the middle cosmetic
channels are all installed and that the connecting hardware is tightened
to the cabinet.
2. Verify that the four (4) lifting clips have corresponding internal lifting
clips installed and connected. Lifting clip holes are 30 mm.
3. Figure 3.1 is only for lifting demonstration purpose. The lifting parts
may be different depending on customers’ decision and availability
of the lifting hardware. Verify shipping weight and capacity of lifting
equipment.
4. As shown in Figure 3.1, the angle between the slings and horizontal
must be 45° or more (70° is ideal).
5. The centre to centre distance of the two lifting points of the lifting
angle or beam is to be 882 mm +/- 150 mm (34” +/- 6.0”).

Transportation and Handling 3-3
Rod or Pipe Rollers
This method is only suitable when there are no inclines and the controller
is being moved on level fl oor.
Boards 50 mm X 152 mm (2” x 6”) or equivalent and at least 300 mm
longer than the controller must be placed under the shipping skid, as shown
in Figure 3.2.
Carefully ease the shipping skid over the rollers until the equipment weight
is borne on the rollers.
The controller can be rolled to its desired location. Steady the load to prevent
tipping.
Minimum 50 mm x 152 mm (2 in. x 6 in.)

3-4 Transportation and Handling
Fork Lift Truck
A single fork lift truck may be used, extreme caution must be exercised.
1. Insert the forks into openings of the shipping skid from the rear of the
controller.
2. Carefully balance the controller on the forks and apply safety straps.
Shipping Skid Removal
Internal access is required to remove the wooden shipping skid from the
Motor Control Center cabinets. External angle brackets attached to the
enclosure are used to attach the enclosure to the wooden skid.
Remove the angle brackets and the associated hardware.
When the enclosure is lifted by overhead means the wooden skid can be
removed.
