Mounting notes
∂ Ensure that the relevant national safety regulations and notes on standards are
complied with
∂ In the geographical areas where DIN regulations are in use, the requirements of
VDE must be complied with, especially DIN/VDE 0100, 0550 and DIN/VDE 0722
∂ Make certain that the actuator is not exposed to direct solar radiation
∂ Required tightening torques for the fixing screws of the
- housing cover: 3.5 Nm
- connecting cover: 2 Nm
∂ The connection between actuator drive shaft and controlling element must be
flexible but torsionally rigid couplings with free from backlash
Β
Note!
Possible connection with drive shaft or hub:
∂ Groove with Woodruff key
∂ Drive shaft with flat edge and matching counter piece
To avoid inadmissible loads and moments by mechanical overload, appropriate actions
must be taken at the mechanical coupling
Example: Metal bellows clutches as compensating clutches with no mechanical play
Only the specified cable may be used (refer to Basic Documentation P7550). The
cable’s shielding must be connected to the printed circuit board using the tab provided.
Warning!
Ensure that the actuator’s housing is connected to functional earth (FE) of the
system.
If necessary, remove isolating layers of paint from the fixing points on the
burner’s casing or run separate earth wires. For detailed information, refer to
«Installation Instructions for the LMV5… system» (J7550.1).

The working range is given on the type field and must be observed when mounting the
actuator. To ensure the actuator is accurately located on the burner, a positioning pin of
6 mm diameter must be fitted on the mounting surface.
