3 Transport and storage

 Consider the weight of the electric cylinder with guide unit.

Depending on the version, the EPCO-KF weighs up to 8 kg.

4 Installation

4.1 Mechanical installation

Mount cylinder

 Do not modify the screws and threaded pins if not directly requested to do so in these operating

instructions.

 Make sure that the device is installed free of mechanical stress and deflection (evenness of the

bearing surface: ≤ 0.2 mm).

 Position the EPCO-KF so that all of the operating elements are accessible.

 Mount the EPCO using the mounting accessories.

 Tighten the mounting screws evenly.

Installation of the payload

Note

If pins strike against the yoke plate, the mechanical connection can be destroyed

 Push a metal plate between the yoke plate and the housing as a counterholder.

 Then press the required pins into the yoke plate.

 Place the centre of gravity of the payload as close as pos

sible to the centre of the yoke plate.

 Attach the payload to the yoke plate in the retracted end

position.

The piston/guide rods bend, depending on the payload

(èAppendix, Characteristic curves).
