INSTALLATION
These actuators are designed for single-point mounting.
IMPORTANT
In order to prevent equipment damage, you must
remove power or set the rotation direction switch to
the "Service/Off" position before manual operation.
Mounting Instructions
All information and steps are included in the Installation
Instructions supplied with the actuator.
Mounting Position
The actuators can be mounted in any position (no IP54 if
mounted upside down; see Fig. 7). Choose a mounting posi-
tion permitting easy access to the actuator's cables and
controls.

Mounting Bracket and Screws
If the actuator is to be mounted directly on a damper shaft,
use the mounting bracket and screws included in the delivery
package.
Self-Centering Shaft Adapter
The self-centering shaft adapter can be used for shafts
having various diameters (3/8...1-1/16" [10...27 mm]) and
shapes (square or round).
In the case of short shafts, the shaft adapter may be
reversed and mounted on the duct side.
Stroke Limitation with Mechanical End Limits
The mechanical end limits (177 lb-in [20 Nm] models, only)
enable the stroke to be limited from 0...90° in increments of
3°.
Wiring
Connecting to the Power Supply
In order to comply with protection class II, the power source
of 24 V actuators must be reliably separated from the net-
work power supply circuits as per DIN VDE 0106, part 101.
Access Cover
To facilitate wiring the actuator to the controller, the access
cover can be detached from the actuator.
IMPORTANT
Remove power before detaching the access cover.
Once the access cover has been removed, please
take care to avoid damaging any of the parts now
accessible.
