Warnings
Do:
Ensure that the system is securely positioned prior to any work being undertaken.
If using the system with any electrical equipment, incorporate appropriate earthing and/or other safety circuitry
as required by national standards to protect the operator.
When lifting or moving components, ensure that the proper posture is maintained. Do not lift loads in excess of
nationally recognized safe working limits (25kg per operator in Europe). If in doubt use an appropriately designed
lifting device.
Before lifting the table top, ensure it is unpopulated.
Exercise particular caution if moving the system on a sloping surface.
Ensure all fixings are secure prior to use.
Ensure that proper airflow is maintained to any electrical equipment installed on the system.
Do not:
Use the system outdoors. The system is designed for indoor use only.
Get into any position where you can be trapped between a wall, door frame or other immovable object and the
system.
Go underneath the system when the unit is being moved.

Chapter 2 Installation
2.1 General Description
Thorlabs rigid nonisolating supports are designed for use in applications which do not warrant vibration isolation, such as an
ultra short pulse laser system. They provide an economical support structure for an optical table under heavy loading and
feature manual levelling adjustment on each support to compensate for uneven floors. Each nonisolating support has an
adjustment pad to level the optical table or adjust the table height over a +15 mm, -8 mm (+0.59", -0.31") range.
A choice of height allows any of the standard Thorlabs table tops to be mounted at a nominal working height of 910mm (36 in.)
above the floor.

2.2 Parts List
The following items are supplied as standard:
4 rigid supports
2 adjustment wrenches
2.2.1 Preparation
Ensure that the floor of the installation site is flat and horizontal to within 12 mm, (i.e. +/- 6.5 mm).
Height Adjustment Nut
Locking Nut
Support Pad

2.3 Installation
1) Position the supports in approximately the correct position for the table – see Fig. 2.2 for dimensions.
Fig. 2.2 Support positions
2.3.1 Mounting the Table on the Supports
1) Raise the table on a fork-lift truck, ensuring that the fork distance is set such that the forks can pass between the
supports when the table is lowered into position – See Fig. 2.3.
Fig. 2.3 Distance between forks
2) Manoeuvre the fork-lift truck until the table is over the supports. Carefully lower the table until it is around 20mm above
the supports.
3) Lower the table onto the supports.
4) When the table is resting on the supports, remove the fork-lift truck.
Note
During item 1, two people, one on each side, should be employed in positioning the supports.

Chapter 3 Joined Systems
The location and pneumatic connections for a joined system will depend on the configuration of the system. Some typical
examples are shown below. Please contact your local tech support office for more details.
3.1 Smaller Systems
Although single tables require four isolators, smaller joined systems may require only six rather than eight isolators. The
number of isolators required will depend upon the joiner configuration and the size of the tables. Contact tech support for
detmore details of a specific system attangement.

3.2 Larger Systems
Depending on the configuration of the joiner, larger systems may require eight or more isolators as shown below.
