3 Installation Instructions
Installation work of any kind of actuator may only be performed by qualified personnel.

3.1 Mechanical Connection

Make sure that the fitting flanges and the actuator flanges match each other, and that the borehole matches
the shaft or, in the case of actuator model "A"(threaded bushing), that the actuator and fitting threads match
each other.
Grease the spindle.
Clean all exposed parts which have been coated with anti-corrosive.
Thoroughly clean the bolting surfaces of the fittings.
Lightly grease the connecting joints between the actuator and the fittings.
Place the actuator on the fittings or the gear.
Tighten the fastening screws crosswise (torque acc. below table).

For output type A (unbored threaded bushing), you must sufficiently lubricate both needle bearings in
the output form after processing and cleaning the spindle nut.
For this purpose, use the optional SCHIEBEL grease lubricant or a grease lubricant according to our recom-
mendation (capter 7, page 13).

3.2 Electrical Connection

Electrical connections may only be carried out by qualified personnel.
Please observe all relevant national security requirements, guidelines, and regulations.
The equipment should be de-energized before working on electrical connections.
Furthermore, confirm the absence of electrostatic discharges during the connection.
First of all, connect the ground screw.
The line and short circuit protection must be done on the system side.
The ability to unlock the actuator is to be provided for maintenance purposes.
For the dimensioning the rated current is to be used (see Technical Data).
Check whether the power supply (voltage, frequency) is consistent with the connection data (see
name plate of the motor)
The connection of electrical wiring must follow the circuit diagram.
This can be found in the appendix of the documentation. The circuit diagram can be ordered from SCHIEBEL
by specifying the serial number.
The standard model can be ordered with the following connection options:
