Rotation of electric motor
Once the electrical connection of the burner is executed, remember to check the rotation
of the electrical motor (pump motor if any, and fan motor) . The motor should rotate accor-
ding to the “arrow” symbol on the body. In the event of wrong rotation, reverse the three-
phase supply and check again the rotation of the motor.
NOTE: the burners are supplied for three-phase 380/400/415/480 V supply, and in the case of three-phase 220/230/240 V sup-
ply it is necessary to modify the electrical connections into the terminal box of the electric motor and replace the overload
tripped relay.
Note on electrical supply
In the case where the power supply of the AUXILIARIES of the phase-phase burner (without a neutral), for the flame detection it is
necessary to connect the RC circuit Siemens between the terminal 2 (terminal X3-04-4 in case of LMV2x, LMV3x, LMV5x, LME7x) of
the base and the earth terminal, RC466890660. For LMV5 control box, please refer to the clabeling recommendations avaible on the
Siemens CD attached to the burner
Configuration with separate electrical panel (optional)
The length of the electrical cables must comply with the provisions in the technical sheets of the equipment or the advice the company
gives at the time of the offer/contract.
Provide sufficient protections for cables and connectors, taking into consideration positioning spaces and the panel-burner tracing sur-
faces. Always consult beforehand the electrical drawings supplied in relationship to the topography of the feeding systems.
ATTENTION: check the calibration of the thermal relay sensor (+5% ÷
+10% rated value).
DANGER! Incorrect motor rotation can seriously damage property and injure people.
