1 Installation notes 4/21/2020
1 Installation notes
Always run the high-voltage ignition cables separately from the LMV6 and other
cables while observing the greatest possible distances
Do not mix up phase and neutral (midpoint) conductors
Install switches, fuses, and grounding in accordance with local regulations
The connection diagrams show the LMV6 with earthed neutral conductor. It is
essential to ensure that local regulations are complied with (e.g., protection against
electric shock)
Do not exceed the maximum permissible current rating of the connection terminals
Ensure that the electrical wiring inside the burner complies with national and local
regulations
Do not feed external mains voltage to the control outputs of the LMV6. When
checking the functions of the burner components controlled by the LMV6 (fuel
valves or similar), the LMV6 must not be connected to the burner components
Mains power may only be supplied via Land N. There must be no difference in
potential between the neutral conductor Nand protective earth PE
Circuit breakers should have a characteristic “C” when operated with the LMV6
Make certain that strain relief of the connected cables is in compliance with the
relevant standards (e.g., as per DIN EN 60730 and DIN EN 60335)
Ensure that spliced wires cannot come into contact with neighboring connections.
Use suitable ferrules. Failure to observe this information poses a risk of loss of
safety functions and a risk of electric shock
Unused connections on the LMV6 must be fitted with a corresponding AGG9
connector by the burner manufacturer
The AGG9 connectors on the connection cables for the LMV6 may only be removed
or replaced when the plant is shut down (all-pole disconnection)
The connection between the SQM4 and the controlling elements for fuel and
combustion air, as well as any additional controlling elements, must be form-fitted
The AZL66 must be used in a dry and clean environment
Check the connection cables for the supervision switch inputs (e.g., the air pressure
switch) for signs of a short circuit

1 Installation notes 4/21/2020
1.1 Electrical connection of the flame detectors
It is important to achieve practically disturbance-free and loss-free signal transmission:
Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
Observe the permissible detector cable lengths; refer to the Technical data
The mains-powered ionization probe does not offer protection against electric
shock hazards. Protection against accidental contact must be ensured. Failure to
observe this information poses a risk of electric shock
Position the ignition electrode and the ionization probe in such a way that the
ignition spark cannot arc over to the ionization probe (risk of electrical overloads)
and adversely affect the ionization supervision process
Insulation resistance
– Must be > 50 mbetween ionization probe and ground
– Soiled detector holders reduce the insulation resistance, thus supporting
creepage currents
Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not suffice
