DNCE
For installation in a vertical or inclined position:
Warning
Uncontrolled moving masses can cause injury to
people or damage to property (squeezing).
If there is a spindle nut fracture inside the DNCE or
a toothed belt breaks
when using parallel kit EAMM-...-U (e. g. due to
wear), the work mass will fall down.
• Check whether additional external safety
measures against spindle nut fracture are
necessary (e.g. toothed latches or moving
bolts). In this way you can prevent the work
mass from sliding down.
• Examine the toothed belt of the parallel kit
regularly for wear
( Parallel kit assembly instructions).
Installing the effective load
• Place the centre of gravity of the work load if possible cent-
rically to the piston rod.
• Fasten the work load to the piston rod.
The wrench flat 8 can be used for counter holding.
The piston rod will bend depending on the effective load
( diagrams in the appendix "Characteristic curves").

Effective loads with their own guide (e. g. with FENG):
• Adjust the guide of the effective load and of the DNCE so
that they are exactly parallel. You will then avoid
overloading the guide (wear).
• Avoid collision between the guide and tubing of the
pressure compensation opening (only for DNCE-...-P5).
• If necessary, turn the motor unit MTR-DCI in the coupling
housing ( Motor mounting kit assembly instructions).
