4.1 Mechanical installation / mounting

For mounting and limitations on mounting (location / position), consulting the

mounting instruction M3544 ([2]) or M3545 ([4]) is mandatory.

The permissible ambient temperature and ambient humidity must be observed.

The actuator may only be manually operated when separated from power

supply.

If required, the angular rotation can be set by appropriate adjustment of the

adjusting screw.

When using the connecting cable with the 6- or 7-pin plug, attach the strain relief

strip at the cable to the VAV compact and modular controllers as shown in the

following illustration.
