Using the "IP Ship Kit"
All standard configurations will pass IP20 specifications with the following exception:
All standard configurations can be configured to pass IP30 specifications by utilizing the “IP ship kit”
supplied with each unit as follows:
Using the supplied plugs, cover all counter-bored base mounting holes that are not covered by your mounting
surface. The plugs should be installed from the outside of the unit with the flange flush to the bottom surface.
The plugs are clear plastic. Depending on the travel length, some plugs will not be used.
Using the supplied set screws, plug all unused carriage mounting holes that are not covered by the load or
load plate. Note: Only insert the set screws until they are flush or slightly recessed from the mounting surface.
If they are inserted too deeply they will make contact with the extrusion or center cover and may cause failure.
Using the supplied set screws, plug all threaded base mounting holes that are not covered by your mounting
surface. Depending on the travel length, some set screws will not be used.
Using the supplied set screws, plug the exposed threaded holes on both end blocks of the unit. A few drops of
Loctite should be applied to the threads prior to insertion to ensure they do not come loose during normal
operation.
