 Each time work has been carried out (mounting, installation, service work, shut
down, etc.), check to ensure that wiring and catch mechanism of the BCI interface
(jack RJ11) into the AZL2... housing and parameterization is in an orderly state. If
this is not observed, there is a risk of loss of safety functions and a risk of electric
shock
 Fall or shock can adversely affect the safety functions. Such units must not be put
into operation, even if they do not exhibit any damage. If this is not observed, there
is a risk of loss of safety functions and a risk of electric shock
