Notes on product liability
AZL66 units may only be used in building services plant and only in compliance
with the applications described in this document.
Compliance with all requirements described in the following chapters is a
mandatory condition for using the AZL66.
Local safety regulations (installation, etc.) must be complied with.
It is not permitted to open AZL66 units. The warranty obligation shall become void
if this requirement is violated.
Caution
It is not permitted to open, interfere with, or modify the AZL66.
All activities (mounting, installation, service work, etc.) must be performed by
qualified staff
Before carrying out any wiring changes in the connection area, isolate the plant
from the power supply (all-pole disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. Failure to observe this
information poses a risk of electric shock
Take suitable measures to provide protection against accidental contact at the
electrical connections. Failure to observe this information poses a risk of electric
shock
On completion of every task (mounting, installation, service work, shutdown, etc.)
always check that the CAN interface is wired and connected correctly (RAST3.81
jack) in the AZL66 housing and that the parameter settings have been made
correctly. Failure to observe this information poses a risk of damaging the safety
functions and a risk of electric shock
These AZL66 units must not be put into operation following impact or shock; even if
they do not exhibit any visible damage, their safety functions may be impaired.
Failure to observe this information poses a risk of damaging the safety functions
and a risk of electric shock
The burner or boiler manufacturer must ensure degree of protection IP40 / IP54 for
the LMV6 and AZL66 as per DIN EN 60529. Failure to observe this information
poses a risk of damaging the safety functions and a risk of electric shock
Siemens does not assume responsibility for damage resulting from unauthorized
interventions.
Electromagnetic emissions must be checked on an application-specific basis!
Only
qualified personnel
are allowed to start up and operate the AZL66. Qualified
personnel in the context of the safety-related notes contained in this data sheet are
persons who are authorized to commission, ground, and tag units, systems, and
electrical circuits in compliance with established safety practices and standards.
Note the following:
The AZL66 may only be used for the applications described in the technical
documentation and only in connection with Siemens burner management systems.
The AZL66 can only function correctly and safely if shipped, stored, set up, and
installed correctly, and operated and maintained with care.
