5 Product overview
5.1 Function
The electric cylinder converts the rotary motion of the mounted motor into a linear
motion of the nonrotating piston rod. The lead screw converts the torque of the
motor into a feed force. The linear movement of the piston rod is precisely guided
by the guide in the bearing cap. Sensors enable the monitoring of end positions,
reference position and intermediate position.

7 Mounting
7.1 Safety
WARNING!
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
7.2 Unpacking
1. Open the packaging.
2. Remove all transport materials (e.g.foils, caps, cardboard boxes).
3. Remove the product from the packaging and place it on the mounting surface.
4. Dispose of packaging and transport materials è 13 Disposal.
7.3 Mounting the Motor
Lateral Force on the Drive Shaft
When mounting the motor and motor mounting kit, do not exceed the max. lateral
force Fq of the drive shaft (forexample toothed belt tension when mounting the
parallel kit) è 14.2 Characteristic Curves.
