Warning notes
For additional safety notes, refer to the Basic Documentation of the LMV5... sys-
tem (P7550)!
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
The LMV5... is a safety device! Do not open, interfere with or modify the unit.
Siemens will not assume responsibility for any damage resulting from unauthor-
ized interference!
• All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
• Before making any wiring changes in the connection area of the LMV5..., com-
pletely 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 and by securing the housing cover
• 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»
• 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
