Warning notes

To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
The LME7... are safety devices! Do not open, interfere with or modify the unit.
Siemens does not assume responsibility for damage resulting from unauthorized
interference!
• 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 burner control's connection terminals (e. g. with dummy plug for not used inputs
and outputs). If not observed, there is a risk of electric shock hazard
• The space where the program module is located is defined as plugging space and
therefore back-off-hand-proof when the program module is not fitted
• Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring and parameterization is in an orderly state and make the
safety checks as described in «Commissioning notes». If not observed, there is a
risk of impairment from safety functions and of electric shock hazard
• If the housing or the area near the operating panel is damaged, the unit must imme-
diately be put out of operation. If not observed, there is a risk of electric shock haz-
ard
• Press the buttons on the operating panel only manually without using any tools or
pointed objects. If the film of the operating panel is damaged, there is a risk of elec-
tric shock hazard
• The data line for the AZL2... or other accessories, such as the OCI410... (plugs into
the BCI), must be connected or disconnected only when the burner control is dead
(all-polar disconnection), since the BCI does not ensure safe separation from mains
voltage. If not observed, there is a risk of electric shock hazard
• If the BCI (jack RJ11) is not used, protection against electric shock hazard must be
provided (jack must be covered up). If not observed, there is a risk of electric shock
hazard
• Fall or shock can adversely affect the safety functions. Such burner controls must
not be put into operation, even if they do not exhibit any damage. If not observed,
there is a risk of impairment from safety functions and of electric shock hazard
• To ensure protection against electric shock hazard, make certain that, prior to swit-
ching on power, the signal cable AGV50... is correctly connected to the AZL2...
• The mains-powered ionization probe is not protected against electric shock hazard.
Protection against accidental contact must be ensured. If not observed, there is a
risk of electric shock hazard
