To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not open, interfere with or modify the flame detector!
All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
Before making any wiring changes in the connection area, completely isolate the
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. If not observed, there is
a risk of electric shock hazard
Ensure protection against electric shock hazard by providing adequate protection
for the connection terminals. If this is not observed, there is a risk of electric shock
Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state.
risk of loss of safety functions and a risk of electric shock
Fall or shock can adversely affect the safety functions. Such flame detectors or
burner controls must not be put into operation, even if they do not exhibit any dam-
If this is not observed, there is a risk of loss of safety functions and a risk

of electric shock
Ensure that the relevant national safety regulations are complied with
The flame detector plugs into the burner (the detector's clamp engages on the
burner's light metal flange)
Always run the high-voltage ignition cables separate from the unit and other cables
while observing the greatest possible distances
It is important to achieve practically disturbance- 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 Type summary and Tech-
nical Data)
If this is not observed, there is a
